How plants use glucose
HOW PLANTS USE GLUCOSE
1) FOR RESPIRATION
Plants manafacture glucose in their leaves. They use some of the glucose for respiration. This realeases energy which enables them to convert the resr of the glucose into various other useful substances which they can use to build new cells and grow. To produce some of these substances they also need to gather a few minerals from the soil.
2) MAKING CELL WALLS
Glucose is converted into cellulose for making strong cell walls especially in a rapidly growing plant/
3) MAKING PROTEINS
Glucose is combined with nitrate ions, which are absorbed from the soil, to make an amino acids, which are then made into proteins.
4) STORED IN SEEDS
Glucose is turned into lipids for storing in seeds.
5) STORED AS STARCH
Glucose is turned into starch and stored in roots, stems and leaves, ready for use when photosynthesis isn't happening, like in the winter. Starch is insoluble which makes it much better for storing than glucose - a cell with lots of glucose would draw in loads of water and swell up.
