pioneer species are photosynthetic‚ there are a few limiting factors that affect the rate of photosynthesis: 1. Light Intensity: As light intensity increases‚ the rate of light-dependent reactions that take place during photosynthesis‚ and therefore photosynthesis‚ generally increases proportionately. However‚ as the light intensity is increased‚ another factor will eventually limit the rate of photosynthesis 2. Carbon Dioxide Concentration: An increase in the carbon dioxide concentration increases
Premium Water Photosynthesis Plant physiology
Plant Cells and Solar Cells Photosynthesis is the process of producing and releasing oxygen in the air. It needs sunlight‚ carbon dioxide and water. During the process of photosynthesis‚ the plants decompose the molecules of hydrogen and carbon-dioxide into hydrogen; carbon and oxygen produce glucose which forms the source of their energy‚ growth and food. Few years ago we knew that the only source of energy is photosynthesis which is used by plants to harness solar energy. Nowadays

creating high hydrogen ion concentration. Photosynthesis: • What is the overall goal of photosynthesis? The overall goal of photosynthesis is to chemically change light into energy. • Because photosynthesis only occurs in plants‚ why is it essential to animal life? It is essential to animal life not only for nutrients from the plants but also because of the byproduct oxygen that is put out from the plants from the photosynthesis process. • What is the role

(CO2) and water (H2O); the process of photosynthesis is a complex series of chemical reactions resulting in the production of glucose and oxygen (O2). Glucose is a simple sugar‚ which is further processed into fructose and sucrose‚ and any sugars not required immediately to be metabolized for their energy are converted into starches: complex carbohydrates used to store these essential sources of energy for when they are required. The process of photosynthesis is summarized in a series of reactions

smaller ones with energy being released‚ and anabolic reactions e.g. photosynthesis are where smaller molecules are built up into larger ones which require energy. Catabolism provides the energy for organisms to synthesise larger molecules in its anabolic reactions. To release energy‚ ATP is hydrolysed into ADP and Pi (an inorganic phosphate) which releases energy that can be used for energy requiring reactions such as photosynthesis. However to maintain the organisms anabolic reactions‚ ATP must be

Plants that have been previously grown in the dark are incapable of photosynthesis since they lack chlorophyll and many polypeptides needed for light harvesting. But once they have been exposed to light‚ over time‚ reorganization of the plastid membranes occur and all the required enzymes and proteins needed for photosynthesis appear. So undetectable levels of these proteins suddenly appear and become

respiration and oxygenic photosynthesis are two cellular processes that have evolved in similar ways. Cellular respiration is responsible for the process of ATP‚ meanwhile oxygenic photosynthesis is the process of turning light energy into food. It is evident that both of these processes have their own reactants‚ products‚ and biochemical pathways. Both of these processes have evolved from their primitive original state‚ but it is important to understand that oxygenic photosynthesis evolved before aerobic

Introduction: Photosynthesis can be defined as light energy being converted into chemical energy‚ which is a very important process for plants and other organisms. Light can be described in terms of light quantity and light quality. Both of these have an affect on photosynthesis. The more light a plant absorbs the more the plant is able to photosynthesize. This light is absorbed though pigments which have specific interactions with certain light waves (colors). The goal of my first experiment

The rate of these processes increases with an increase in temperature responses is different with different crops. The extent of growth and yield responses of plants to elevated CO2 depends on the photosynthetic pathway. Crops with C3 photosynthesis will respond markedly to increasing CO2 concentrations. Common C3 crops are
