    the two main contributing factors to photosynthesis rate. So in theory as temperature increases and light increases so will the photosynthesis rate. This is because reactions occur when the plant enzymes collide and bind with a substrate. The increase in temperature would mean an increase in the kinetic energy of the plant enzymes meaning they would move faster, and therefore collide more frequently with the substrates, so as a result an increase of photosynthesis occurs. However when a system reaches

  • Elodea Photosynthesis Essay

    981 Words  | 4 Pages

    ________________________________________ Abstract: The process of photosynthesis is the most essential chemical processes that occurs on the planet. Most terrestrial organisms require oxygen to survive and much of the oxygen in the atmosphere is produced by photosynthesis. Plants are the organisms that carry out this chemical reaction and so it is crucial to understand what impacts this process in both terrestrial and aquatic environments. This experiment considers the photosynthesis of aquatic plants and how various concentrations

  • Light Energy In Photosynthesis

    840 Words  | 4 Pages

    In photosynthesis, carbon dioxide and water are used to produce glucose and the by-product oxygen, and there is an intake of energy. In respiration, on the other hand, glucose and oxygen are broken down into carbon dioxide and water, and there is a release of energy. Basically, the products of one serve as the reactants of the other, and vice versa. As the name suggests, light-independent reactions do not need the presence of light to function. The process occurs in the stroma and it produces G3P

    2543 Words  | 11 Pages

    Photosynthesis is the process the energy from sun lights to produce ATP which is used to make sugar such as glucose, sucrose, cellulose, and starch. Photosynthesis involves two different processes, which are light dependent reaction and light independent reaction. Light dependent reaction requires light energy to split water molecules (photolysis) into hydrogen ions (H^+), oxygen (O_2) and electrons to make ATP and the light dependent reaction allows plants to grow and make a waste product (oxygen)

  • Environmental Factors That Affect Photosynthesis

    1205 Words  | 5 Pages

    factors that can affect photosynthesis. Since water is used in photosynthesis, even a slight change in the amount of water can change the amount of oxygen and carbon dioxide release from a plant. This causes their stomata to close. Since the amount of water used in photosynthesis is very small, it acts as a limiting factor indirectly. It can maintain the turgor of assimilatory cells. When the turgor is lost, the stomata closes and photosynthesis decreases. Photosynthesis is affected by water since

    the effect of light intensity on the rate of photosynthesis. Hypothesis Light intensity is directly proportional to the rate of photosynthesis. When the light isn’t intense, not many oxygen bubbles will be produced and thus observed. This indicates that the plant will not have enough derived energy from the sun to activate photosynthesis. Whereas, when the light intensity is great, the rate of photosynthesis will be high. Introduction Photosynthesis is the process of converting energy from sunlight
