Introduction: The rate of photosynthesis varies greatly with changes in wavelengths of light. Light’s colour is determined by its wavelength of light‚ and thus it is possible to devise an experiment to determine which wavelengths of light are most productive for photosynthesis than others. In this experiment I use a plant called Elodea (pond weed). Elodea is native to North America and it is also widely used as aquarium vegetation. The basic structure of these plants are whirls of leaves around

Photosynthesis Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration‚ or converted into starch and stored. Oxygen is produced as a by-product. The equation for photosynthesis: Carbon Dioxide + Water (+ Light Energy) → Glucose + Oxygen Symbol equation: 6CO2 + 6H2O ------> C6H12O6 + 6O2 (http://www.bbc.co.uk/schools/gcsebitesize/science/add_aqa_pre_2011/plants/plants1

Adenosine Triphosphate‚ also known as ATP‚ is the molecule responsible for the energy that we‚ and all other organisms‚ need to survive. It is produced primarily in the processes of aerobic and anaerobic respiration by oxidative and substrate phosphorylation. 4 molecules of ATP are produced from 4 ADP and 4 inorganic phosphates in glycolysis in the cytoplasm of every cell‚ by the oxidation of a triose phosphate into two molecules of pyruvate. In anaerobic respiration these are the only 4 ATP

wildlife? We must make a conscious effort to conserve the world’s plants and animals. Plants are essential for our own survival. Plants use the sun’s energy to make food—a process called photosynthesis. Therefore plants are the first important link in the food chain of which humans also form a part. During photosynthesis‚ oxygen is released and oxygen is vital for the existence of life itself. Animals need plants in order to survive‚ but plants also need animals. Animals and plants are therefore

A. C4 and CAM plants are plants that use certain special compounds to gather carbon dioxide (CO 2 ) during photosynthesis. Using these compounds allows these plants to extract more CO 2 from a given amount of air‚ helping them prevent water loss in dry climates. CAM and C4 plants are similar with the exception that CAM only opens up the stomata’s at night. They both photosynthesis at the same rate for the majority at a time and are tolerate to heat. Plus C4 closes their stomata’s during hot

DISCUSSION Photosynthesis is a process of converting light energy into chemical energy and storing in the bonds of sugar. Photosynthesis takes place in the plant leaves. In the leaves‚ there are mesophyll cells that have chloroplasts‚ where the photosynthesis occurs. During experiment‚ two leaves were tested for the presence and localization of starch. One leaf was a light-grown plant with mask‚ and the other was a dark-grown plant with mask. Both leaves were soaked in iodine solution and then

called photosynthesis. This process assists in nourishing plants and keeping them alive. For example‚ trees grow very tall in the rainforest where there is an abundance of water in order to reach as much light as they can. For this reason‚ in order to survive the chloroplast in plants must capture light energy from the sun and convert it into chemical energy that is stored in sugar and other organic molecules (Photosynthesis‚ 2014‚ p. 185). In plants that contain chlorophyll‚ the photosynthesis process

For each type‚ describe its role in determining protein structure. Different types of bonds/interactions in proteins lead to different kinds of structures. Three of the most commonly known chemical bonds in proteins include the hydrogen bond‚ the covalent bond‚ and the ionic bond. In hydrogen bonds‚ hydrogen interacts with
