Uses of Photosynthetic Carbohydrate
What is Uses of Photosynthetic Carbohydrate?
The glucose made in photosynthesis has four required fates in a plant: it is used in respiration to release energy, converted to starch for storage, converted to cellulose to build cell walls, and converted to sucrose for transport in the phloem. Starch is the storage form because it is insoluble and so does not affect the water potential of the cell.
This definition is part of the Plant Nutrition chapter in Cambridge O Level Biology.
