1. From this experiment, you can conclude that the stomata are typically found on the lower epidermis of the leaf. In this experiment we observed on average 67 stomata on the monocot lower surface, versus 32 stomata on the upper epidermis. In the dicot there was even a greater margin, with 2 stomata in the upper epidermis, and 51 stomata in the lower epidermis. In addition you could see how the dicot and monocot stomata differed: the dicot stomata were arranged in an irregular pattern, while the

In 2010 there was a proposal to get rid of these plants that covered the floor of the reservoir. These plants were called Hydrilla. The Hydrilla had overgrown so much that they expanded from 730 acres that April to 840 acres in December. The reason that this plant was growing to be such an issue, was that it was getting caught up in the propellers of the electric motors on boats and it also kept swimmers at bay. There were multiple ideas to have the hydrilla removed such as dredging, lake draining

The effects of light intensity on oxygen release of Elodea. Light is a necessity in the functions of life. Without light, phototrophs like Protista, Fungi and Monera will simply not respire. Photosynthesis will not occur and therefore plant-life will perish resulting in Earth’s atmosphere having an insufficient amount of oxygen. This deficiency of light will affect how all organisms conduct respiration. Additionally, the conversion of light intensity to glucose, water and oxygen is regarded as a

Abstract In the lab we examined the effects of tobacco smoke on mollusc gill cilia. To conduct this lab a cigarette with a filter was used and a cigarette without a filter was used to determine which ones affected the mollusc gill cilia in a negative way. It was hypothesized that the cigarette without the filter would slow the movement of the cilia down and we could determine this by counting the BPM (beats per minute). While we did use filtered and non-filtered cigarettes we also had a control

1. Make a hypothesis about which color in the visible spectrum causes the most plant growth and which color in the visible spectrum causes the least plant growth? If the different light colors affect the plants' growth then the most absorbed colors result in the most growth and the least absorbed ones will cause the least plant growth. 2. How did you test your hypothesis? Which variables did you control in your experiment and which variable did you change in order to compare your growth results

What’s the difference? The main difference between these two food webs is in the one on the right, there will be more of the species that the Lynx eats because less are being eaten by the lynx, and there would be less of the predators of the Lynx because there would be less food for the predators to eat. What is their ecosystem like? The Lynx like to be in a wet environment. Their ecosystem is mainly in dense forests or sometimes environments with rocky outcroppings. The Lynx lives

TITLE - How does plant growth get affected when it’s provided a different type of water? Independent Variable - Weeks Dependent Variable - Plant’s growth in Meters PURPOSE - The purpose of the lab was to test plant’s growth level when it was given different sources of water for 3 weeks. BACKGROUND INFORMATION - Water is affecting our nature, humans, all living organisms because water can sometimes be toxic to anyone and mostly to plants. Plants need sufficient water that is good quality and

about photosynthesis. Green plants create the food and oxygen that all animals need to survive which is through photosynthesis. It is fueled by the green pigment inside the plant cells called chlorophyll which absorbs the energy from sunlight. The plant’s leaves draw water molecules from the earth and absorbs carbon dioxide from the air and then recombine the water’s hydrogen with carbon and oxygen to make food releasing new oxygen. Plants manufacture their own food through photosynthesis. Plants

Ecosystem Structure, Function, and Change SCI/256 October 30, 2013 Edward Chargualaf Ecosystem Structure, Function, and Change In San Diego, California there is a beach area known as “The Jewel” or La Jolla. The children’s pool, La Jolla shores, and La Jolla cove make up this mile long crescent of a prime sandy beach. The children’s pool is a small cove protected by a concrete wall originally built to make a safe swimming area for children. Now the area has turned into a place for seals

Carbon Dioxide in Organisms and Ecosystems. Carbon forms the backbone of all organic molecules that make up the bodies of organisms; including carbohydrates, lipids and proteins. The carbon atoms that make up each organism have got there as a result of being part of another organism. Carbon isn’t just in animals, carbon is a fundamental atom found in every ecosystem. An ecosystem consists of abiotic and biotic features in a given area at a given time. The Carbon Cycle shows how carbon is passed
