Background. Plants require light to grow. Plants store energy in their cells which in turn generate food and help them grow. The aim of this experiment is to show the importance of light as an important part of plant life. Light leads to the development of chlorophyll. This is used by plants to store energy during daylight. This is the energy that the plant will use to make food. Hypothesis. Plants need light in order for them to make food. It is important to grow plants in conditions that expose

Plant-Based Diets Erik van der Lee Saddleback College People ask me why I don't eat meat. Some arguments for not eating it include health, longevity, performance, environment and ethics. Each of these arguments could stand alone and be strong enough by themselves, but if you combine them together the argument is overwhelming. Surely if you currently eat meat at least one of these arguments must appeal to you, if not why not? I think I should be asking the question, "Why do you eat meat?"

used to aeration of lawns) * Light sources * Water Drying oven or blotting paper and plant press for drying of plant material * Aluminum foil * Spoons or indoor garden spades to remove plants * String or other marking method to mark plot boundaries * Other supplies to vary growth conditions as desired Procedure 1. Take 5 Complete Plants from the soil. 2. Place the plants on an open container made from aluminum foil, and let dry in a high temperature(Microwave)

distance moved by the pigment from its original position B= distance moved by solvent from the same position. *Round Rf values to 2 decimal places CONCLUSION: We used paper chromatography to separate the pigments found in spinach. Since plants use several different pigments to capture light energy for the light dependent reaction in photosynthesis, we expected that we would see several different bands of pigments on our chromatography paper. As the data in Table 1 indicates, we obtained

Exercise 28 1. Rhizoids serve to anchor the plant to the substrate and absorb water and minerals. Also, the rhizoid attaches the gametophyte to the substratum and facilitates the absorption of minerals and water. Anchorage + absorption. Rhizoids are nonphotosynthetic and anchor the protonema to the substratum. 2. Each pore leads into an air chamber containing columns of photosynthetic cells and facilitates in gas exchange. Unlike the stomata of vascular plants which close in dry weather, the air pores

Gardening was a part of daily life. Hence, it becomes vital I let you know a few of the numerous importance of gardening to man and his environment. A garden is a planned space, usually outdoors, set aside for the display, cultivation, and enjoyment of plants and other forms of nature. Gardening is the activity of growing and maintaining the garden. Ask any gardener today why they garden and you will get a variety of reasons why it’s important to them. The daily reports of food-borne illnesses emanating

unicellular genera such as Chlorella and the diatoms to multicellular forms such as the giant kelp, a large brown alga that may grow up to 50 meters in length. Most are autotrophic and lack many of the distinct cell and tissue types found in land plants such as stomata, xylem and phloem. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the Charophyta, a division of algae that includes Spirogyra and the stoneworts. There is no generally accepted

conditions for growing healthy, dense turf. Algae are unicellular or multicellular threadlike green plants that form a thin dense green scum over the soil surface. This scum forms a tough black crust when dry which acts as a barrier impeding the entrance of water and nutrients into the soil. Algae are competitive in compacted, waterlogged soils and during warm, sunny, humid conditions. Mosses are green plants with leaves arising from all sides of a central axis. Mosses may grow erect or prostrate. They
