Photosynthesis

• Photosynthesis can be defined as the process by which plants manufacture carbohydrates from raw materials using energy from light
• Glucose and oxygen are produced as products of photosynthesis
• Algae and some bacteria are also photosynthetic
• Glucose


  The food produced by plants through photosynthesis
• Food produced by plants through photosynthesis is important for other organisms that feed on the plants
• Algae


  A group of organisms that photosynthesise but lack the complex range of cell types and organs found in land plants
• Biomass


  The dry mass of an organism, which will increase as a result of photosynthesis
• Photosynthesis


  Carbon dioxide + water ---> glucose + oxygen
• Carbon dioxide

  A gaseous compound of carbon and oxygen, which is a by-product of respiration, and which is needed by plants for photosynthesis
• Endothermic


  Reaction in which energy is taken in
• Chlorophyll


  The green chemical inside the chloroplasts of plant cells that enables photosynthesis to take place
• Chloroplast


  Contains the green pigment chlorophyll; the site of photosynthesis
• Cell


  Basic unit of life
• Organ


  A group of different tissues that work together to carry out a particular function
• Stomata


  Tiny holes in the epidermis (skin) of a leaf that control gas exchange
• Xylem is responsible for the transport of water and minerals in plant
• Respiration


  The chemical change that takes place inside living cells, which uses glucose and oxygen to release the energy that organisms need to live
• • Photosynthesis can be defined as the process by which plants manufacture carbohydrates from raw materials using energy from light
• The chemical equation of photosynthesis is 6CO2 + 6H20 --------- C6H12O6 + 6O2
• what does xylem transport

  water and mineral ions
