Use & Storage of Carbohydrates: Extended

Extended Tier Only

• The carbohydrates produced by plants during photosynthesis are used in various ways, e.g.

  • Converted into starch molecules for energy storage inside cells

  • Converted into cellulose to build cell walls

  • Glucose can be used in respiration to release energy

  • Converted to sucrose for transport in the phloem

  • During production of nectar to attract insects for pollination

• Plants can also convert carbohydrates into lipids and amino acids
