  • How plants use glucose
    • For respiration
      • Plants manufacture glucose in their leaves
      • They then use some of the glucose for repiration
      • Engery release enables them to convert the rest of the glucose into various other useful substances, which they can use to build new cells and grow
      • To produce some other substances they also need to gather a few minerals from the soil
    • Making cell walls
      • Glucose is converted into cellulose for making strong cell walls
    • Making proteins
      • Glucose is combined with nitrate ions to make amino acids which are made into proteins
    • Stored in seeds
      • Glucose is turned into lipids for storing in seeds
      • Seeds also store a lot of starch
    • Stored as starch
      • Glucose is turned into starch and stored in roots, stems and leaves, and used for when photosynthesis isn't happening
      • Starch is insoluble which makes it much better for storing than glusoce
