Uses of Glucose
Respiration
Plants use the glucose from photosynthesis for respiration, which occurs in the mitochondria of the cells
The chemical reaction releases energy which converts the rest of the glucose into other substances which can be used to build new cells and grow
To produce some of the substances, the plant also absorbs minerals from the soil.
Storage
Since glucose is soluble, it is converted to insoluble starch for storage. That starch can be sored in the roots, leaves and stems - they can be used when photosynthesis is not ocurring during winter.
Potato and carrot plants store starch underground during the winter - we eat the swollen storage fruit.
Protein Synthesis
Nitrates combined with glucose make up amino acids, which are then turned into proteins.
-
Enzymes are made of proteins which make up parts of plants. Even organelles within cells are made up of proteins.
Nuts and seeds also contain large amounts of protein so that it can sustain the plant's first few days of life

Cellulose
Cell walls in plant cells are made of converted glucose called cellulose. The cell wall is the tough layer that surrounds the plant cell.
The cell wall is located outside the cell membrane and it provides structural support and protection.
-
Another important function of the cell wall is to act as a pressure vessel to prevent the plant from over-expanding when water enters the cell during osmosis.
