...A STORY OF HONESTY A successful business man was growing old and knew it was time to choose a successor to take over the business. Instead of choosing one of his directors or his children, he decided to do something different. He called all the young executives in his company together. “It is time for me to step down and choose the next CEO,” he said.”I have decided to choose one of you.” The young executives were shocked, but the boss continued. “I am going to give each one of you a seed today – a very special seed. I want you plant the seed, water it, and come back here one year from today with what you have grown from the seed I have given you. I will then judge the plants that you bring, and the one I choose will be the next CEO.” One man, named Jim, was there that day and he, like the others, received a seed. He went home and excitedly, told his wife the story. She helped him get a pot, soil and compost and he planted the seed.Every day, he would water it and watch to see if it had grown.After about three weeks, some of the other executives began to talk about their seeds and the plants that were beginning to grow. Jim kept checking his seed, but nothing ever grew.Three weeks, four weeks, five weeks went by, still nothing. By now,others were talking about their plants, but Jim didn’t have a plant and he felt like a failure.Six months went by – still nothing in Jim’s pot. He just knew he had killed his seed. Everyone else had trees and tall plants, but he had nothing...

...what are the advances in complexity of bryophytes over algae regarding their morphology, habitat,asexual reproduction and sexual reproduction. Bryophytes: are plants that lack vascular tissue and require environmental water to reproduce. General characteristics of this group include: a waxy cuticle to slow down water loss and gametangia that protect developing gametes. The male gamatangium is called the antheridium which produces flagellated sperm. The female archegonium produces a single egg. Bryophytes need water to reproduce. They do not contain any vascular tissue for up right support. These plants usually form mats of horizontally growing tissue. The plant grips the ground with elongated cells called rhizoids. Photosynthesis occurs in the stem-like structures above the matted plant bodies. They undergo an alternation of generations with the haploid generation being the dominant form of this cycle. The sporophytes are generally smaller and depend on the gametophyte for water and protection. Algae The term algae embraces all photosynthetic protists. It refers to an aquatic, photosynthetic way of life, not an evolutionary kinship. Most algae live in water, but some are terrestrial. Most algae live near the surface of the water producing 30 to 50 percent of the earth's oxygen. Algae are classified on the basis of conservative characteristics such as the type of cell wall, flagella, photosynthetic pigments, and the form in which food is stored. They are single celled or live...

...How to grow your own Moss Graffiti http://www.permaculture.co.uk/readers-solutions/how-grow-your-own-moss-graffiti Rozie Apps | Friday, 26th April 2013 Art and creativity can be used in powerful ways. They can cause happiness and sadness, anger and joy. But best of all they can unite communities and rejuvenate old or forgotten areas of cities and towns. Graffiti tends to have a negative impact on communities. Many people do not see it as art, but vandalism to their towns, cities and society. It can cost councils a huge amount of money to remove graffiti and this money could be much better spent. A new style of graffiti has been spreading through the cities of the world, turning brown, white or dull brick walls into greener, brighter and more beautiful spaces for people to see. It is called Moss Graffiti. Also known as Eco-Graffiti or Green-Graffiti, it can be seen as a new style of guerrilla gardening. Instead of using harmful toxic chemicals to make art, moss can be used to make beautiful and harmless pieces of art. It is ecologically sound and can be easily removed by spraying lime juice on the design, which kills the moss spores. A moss zebra If you have a wall at home you'd like to brighten up, or permission from the council to rejuvenate an area in your community, follow this recipe to create some green art. You will need: 1 or 2 clumps (small handful) of moss 2 cups of buttermilk, or you can use yogurt (even vegan yogurt) 2 cups of water Half a teaspoon...

...Pterophyta division. The root like structures, rhizomes, which indicates that this organism has vascular tissue, were sticking out of the gametophytes. All these characteristics correspond to plants in the Pterophyta and Bryophyta division. In the thirds observation, heart shaped gametophytes are visible, verifying the conclusion that this organism is a fern, which is part of the Pterophyta division. The fern gametophyte has circular and the occasional heart shaped leaf. This is a clear indication that this gametophyte is a fern, since the moss gametophyte has long, skinny leaves. Under 10x magnification, scale like cells are visible on the gametophytes. Under the microscope, multiple leaves are growing, layered on top of each other. Ferns and mosses have similar characteristics, but are very different in many ways. Ferns have a vascular system, xylem, and phloem enabling it to transport food and water throughout the leaves, while moss plants lack these structures. Both also alternate their generation, changing from gametophyte to a sporophyte. With a life cycle similar to that of the...

...The Tundra About a fifth of the land surface of the earth is tundra. The tundra is found next to the icy zones in the arctic. The temperatures on the tundra are below freezing and can drop to as low as -70 degrees F. There are winds that can blow up to 100 miles an hour. Temperatures are so cold, the water in the ground freezes, up to a depth of 2000 feet or more. It can reach temperatures of up to 50 degrees F on a warm summer day. There are a few places where only a few inches on the top layer of ground will thaw. This part of the thawed ground is called the active layer. This active layer is always wet because the water from the melted ice cannot drain. The frozen ground that never thaws is called the permafrost layer. The tundra may get less than five inches of precipitation a year, but it is still very wet in the summer. The water that comes from the melting ice has nowhere to go. During the summer, the tundra is one big open, rolling area of ground, covered with many small lakes and ponds. During the summer, days are close to 24 hours long. This is when there is light for the little plants that grow. The plants in the tundra are only about four inches high, many being perennials. The plants consist of grasses, sedges, mosses, little flowering plants, and tiny dwarf willow bushes. They grow in dense round cushions or mats that hug the ground. Hugging the ground helps protect them from the cold and drying winds. In the rocky area, lichens grow on the rocks...

...Colonisation of a wasteland is the plant succession which occurs in an urban area which has been abandoned or untouched for 5 years. This form of colonisation is a form a secondary succession. Plant succession is the process in which one plant species replaces another over time which may be influenced by changes in the environment. The first plants to develop are the pioneer plants. They are able to exist in areas where there is little water, obtaining nutrients by photosynthesis and grow in places with very little soil, like concrete. Some examples of pioneer plants are lichens and mosses. When these plants die they provide a mat of organic matter which, mixed with the weather mineral matter produces a protosoil that other plants can root into. Stage two of the colonisation of the wasteland is when the Oxford ragwort starts to grow. It grows in the cracks in the surface because they provide sheltered places where seeds can germinate and retain moisture. During this stage, plant succession is rapid. As these higher plants die off, they produce a thicker and more nutrient-rich soil. Taller plants can then become established. One of the most common is rosebay willow herb, which spreads initially by seeds and then by rhizomes which can extend up to 1m a year. A rhizome is an elongated horizontal underground plant stem producing shoots above and below the ground. These plants gradually shade out the lower plants stopping them from growing as they can’t photosynthesise. The...

...C Fern Lab Report July 15, 2009 The life cycle of land plants is characterized by an alteration between two phases or generation that is morphologically and functionally different. The gametophytes generation is the sexual phase of the life cycle. C-Ferns have independent haploid and diploid generations, distinct sexual types within the gametophyte generation, and they rapidly develop to full sexual maturity within two weeks. They also possess a variety of distinct visual phenotypes that can be used to perform genetic crosses (Hickok and Warne 1998). A C-Fern sporophyte is a regular diploid plant. This plant undergoes meiosis on special cells on the underside of leaves, resulting in 1N (haploid) spores. The spores undergo mitosis to produce gametophytes, of which there are two separate genders. One gender is the hermaphrodite, which is rather large and heart-shaped, and produces both eggs and a small amount of sperm. The other gametophyte gender is a very small, club-shaped male, which produces sperm only. There are no female-only gametophytes (Hickok and Warne 1998). Germination occurs three to four days and full sexual maturity is attained within six days after germination. At maturity, the gametophyte consists of a small, simple essentially flat thallus with rhizoids, vegetative cells and sexual organs (archegonia and antheridia). Archegonia are female organs that contain one egg each that lies at the base of a small neck that sticks out from the surface...

When the air is humid the elaters coil around the spore so that buoyancy decreases and the spore drops--with luck onto moist soil where it can germinate. 5. a. The leaves are delicate, thin and flat and only one cell thick except at the midrib.A few mosses such as Polytrichum have extra rows of cells, making the leaves harder, drought-resistant and more difficult for chemicals to penetrate 1-2 Cells thick b.

...Question Describe the evolutionary developments that enabled the successful colonisation of terrestrial habitat by the early plant? Plants evolved from an aquatic algal ancestor during the Devonian period. The transition from water to land had some useful advantages. Land provided a good substrate with nutrient rich soils and there were no predators in form of herbivores and microbes. Carbon dioxide concentration in air was very high and readily diffuses in plants than when dissolved in water. Sunlight levels in air were very high and these conditions favoured photosynthesis (Raven et al, 1992). However life on land presented challenges that led to morphological adaptations and to the subsequent evolution of present day plants. Life on earth presented problems of acquisition and distribution of nutrients, preservation of water support and reproduction. The earliest evolutionary adaptation was multicellularity, differentiation and specialisation of structures. The plants evolved an aerial structure that is photosynthetic and functions in gaseous exchange. They also developed an anchorage to the substratum, soil. Meristems evolved and provided the much needed cells that differentiated and specialised into useful structures (Campbell and Reece, 2005). In bryophytes the cells differentiated into rhizoids, antheridia and archegonia, setae and capsule. In Pteridophytes they developed into xylem and phloem, fronds, roots and root hairs (Solomon et al, 2012). This differentiation...

...home after the previous governess died. Douglas begins to read from the written record, and the story shifts to the governess’s point of view as she narrates her strange experience. The governess begins her story with her first day at Bly, the country home, where she meets Flora and a maid named Mrs. Grose. The governess is nervous but feels relieved by Flora’s beauty and charm. The next day she receives a letter from her employer, which contains a letter from Miles’s headmaster saying that Miles cannot return to school. The letter does not specify what Miles has done to deserve expulsion, and, alarmed, the governess questions Mrs. Grose about it. Mrs. Grose admits that Miles has on occasion been bad, but only in the ways boys ought to be. The governess is reassured as she drives to meet Miles. One evening, as the governess strolls around the grounds, she sees a strange man in a tower of the house and exchanges an intense stare with him. She says nothing to Mrs. Grose. Later, she catches the same man glaring into the dining-room window, and she rushes outside to investigate. The man is gone, and the governess looks into the window from outside. Her image in the window frightens Mrs. Grose, who has just walked into the room....

...character? To what extent is her final protest justified? How do the other characters portray themselves by their attitudes toward the ritual? Mrs. Tess Hutchinson stands out right from the start: she arrives at the lottery late. She explains to Mr. Summers that she was doing her dishes and forgot what day it was. The town treats her lateness lightly, but several people comment on it, “in voices just loud enough to be heard across the crowd, ‘Here comes your Missus, Hutchinson,’ and ‘ Bill, she made it after all.’” (Jackson 501). It is ironic that she is the one who wins the lottery, and is fated to be stoned. So Tess Hutchinson has already been noticed by people as one who is not entirely part of the group. Before the drawing she is friendly with the other women, pretending to be pleased to be present. The very moment that she sees is her family that draws the black dot, though, her egotism is evident. “You didn’t give him time enough to take any paper he wanted. I saw you. It wasn’t fair!” (Jackson 504). She continues to scream about the unfairness of the ritual up until her stoning. Mrs. Hutchinson knew the lottery was wrong, but she never did anything about it. She pretends as much as she could to enjoy it, when she truly hated it all along. Maybe Jackson is suggesting that the more hypocritical one is, the more of a target they are. Mrs. Hutchinson was clearly the target of her fears. I think sometimes we have no problem remarking on people’s adultery until it is ourselves that...
