There are many differences between photosynthesis and cellular respiration. Photosynthesis requires energy as photons. Cellular respiration supplies energy in the form of ATP. In photosynthesis‚ electron transport occurs in the membranes of chloroplasts or thylakoid discs. Cellular respiration takes place in the membranes of mitochondria. In photosynthesis‚ water breaks down to supply 2 electrons and 2 Hydrogen ions and release ½ O at the beginning of the chain. In cellular respiration‚ 2 electrons

are large cytoplasmic organelles. Plastids are major organelles found in the cells of plants and algae. Plastids are the site of manufacture and storage of important chemical compounds used by the cell. Plastids often contain pigments used in photosynthesis‚ and the types of pigments present can change or determine the cell’s colour. The term plastid was derived from the Greek word plastikas meaning formed or moulded. This term was coined by Schimper in 1885. In plants‚ plastids may differentiate

sustainable energy source? One process is photosynthesis. In plants‚ cells called chloroplasts collect energy from the sun and use water and carbon dioxide (photosynthesis) to make sugars.1 Light energy (called photons) hit single chlorophyll pigments in the cells of the plant leaves. 2 Photoautotrophs is the term used for plants that create energy out of sunlight. Plants that do not use the sun’s energy are called chemoautotrophs.3 For photosynthesis to begin a few conditions must be met; enough

organisms need to survive. Carbon is the basic building block of all living things. It moves through an ecosystem in a cycle called the carbon cycle. In this cycle carbon in the atmosphere is known as carbon dioxide. Plants use it to perform photosynthesis and make food. Animals then eat the plants that contained the carbon. Carnivores then eat the other animals thus releasing carbon in animals. Both plants and animals respire. Carbon dioxide is returned to the atmosphere through respiration and

Photosynthetic saturation is the maximum rate of photosynthesis. What was the value for photosynthetic saturation in tomato leaves? Answer Light quality does not effect the rate of photosynthesis. Answer Based on what you know about photosynthesis‚ provide possible reasons for what causes photosynthetic saturation (these cannot be determined from the graph). Answer Which color of visible light was least effective for photosynthesis? Answer What is the relationship
Premium Color Light Photosynthesis
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
