photosythesis

• Photosynthesis


  A chemical reaction that occurs in the chloroplasts of plants in which the energy in light is stored in glucose
• Photosynthesis


  • Occurs in the leaves of a plant
  • Needs chlorophyll and light energy
• Photosynthesis


  Carbon dioxide and water converted into oxygen and glucose
• Chlorophyll


  Green pigment found within chloroplast that enables the process of photosynthesis to occur
• Product


  Made in a chemical reaction when atoms separate from each other, rearrange and join together differently
• Glucose


  Acts as a vital source of food for the plant
• Carbon dioxide, water and light are all needed for photosynthesis to take place
• Plants and algae can only carry out photosynthesis in the light
• The oxygen produced is released into the air from the leaves
• The glucose produced can be turned into other substances, such as starch and plant oils, which are used as an energy store
• Respiration


  A chemical reaction that occurs in the mitochondria of cells in which glucose and oxygen react to produce carbon dioxide and water, releasing energy
• Derby County FC uses artificial lighting to overcome shade issues and induce photosynthesis in their grass pitch
• Qualities of a healthy, durable grass pitch


  • Moisture
  • Length of the grass
  • Hardness of the surface
• Without photosynthesis, life as we know it would come to an end, as almost every food chain depends on it either directly or indirectly
• Producer


  The first organism in a food chain. Usually a green plant or alga which stores energy from sunlight as glucose during photosynthesis
• Photosynthesis brings about a balance in the ecosystem as it decreases the concentration of carbon dioxide in the atmosphere
• Without photosynthesis we wouldn't have fossil fuels such as coal and petroleum, as these were formed from photosynthetic processes
• Symbiotic


  Two things working together
• Plants need the carbon dioxide released by respiration and decomposition, whereas animals need the oxygen released by plants from photosynthesis
• The golden jellyfish have a symbiotic relationship with photosynthetic algae, where the algae provide glucose to the jellyfish
• Glucose can be used to make carbohydrates, cellulose, starch, fats, oils and amino acids
• Cellulose is the main component found in plant cell walls and gives plants strength and support
• Starch is a storage form of energy for plants
• Glucose produced in photosynthesis can be used to help make amino acids, which are then used to synthesise proteins
