use of glucose from photosynthesis

Cards (7)

  • What is the glucose produced in photosynthesis used for?
    Respiration by all living cells
    Converted into starch, fats/oils, cellulose and amino acids.
  • Why do plants store glucose as starch?
    Starch is insoluble, so doesn't affect osmosis. Also it is more compact, so easier to store large amounts. The starch is used by cells as a source of glucose for respiration when it is dark.
  • Why do plants convert some glucose to oils?
    Seeds have oils stored in them as the energy supply for the new plant to start to grow (germinate).
  • Why do plants convert some glucose to cellulose?

    Cell walls are made of cellulose. It is strong and helps to support the plant. All plant cells have cell walls.
  • Why do plants convert some glucose to amino acids?
    Amino acids are the building blocks of protein (for growth and repair). Plants need amino acids for protein synthesis. (Plants are responsible for producing many of the amino acids that we rely on too)
  • What else do plants need to turn glucose into amino acids?
    Glucose just contains the elements CHO. Amino acids contain CHON. Plants need to get nitrate ions from the soil to make amino acids.
  • what is the starch stored by plants used for
    respiration after dark
