Use & Storage of Carbohydrates (Cambridge O Level Biology)

• The carbohydrates produced by plants during photosynthesis can be used or stored as follows:
  • Converted into starch molecules; these are an energy store for plant cells
  • Converted into cellulose to build cell walls
  • Glucose can be used in respiration, which releases energy for cell activities
  • Glucose can be converted to sucrose for transport in the phloem
• Plants can also convert the carbohydrates that they produce into lipids and amino acids

Glucose can be used immediately in respiration, or converted into other molecules
