How plants
use glucose
- For respiration
- Plants make glucose in their leaves
- They use some of the glucose for respiration.
- This releases energy which enables them to convert the
rest of the glucose into various other useful substances.
- Which they can use to build new cells and grow.
- 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.
- Plants make glucose in their leaves
- Making cell walls
- Glucose is converted into cellulose for making strong cell
walls, especially in a rapid growing plant like bamboo.

- Making proteins
- Glucose is combined with nitrate ions (absorbed from the
soil) to make amino acids which are then made into proteins.

- Stored in seeds
- Glucose is turned into lipids (fats
and oils) for storing in seeds.
- Sunflower seeds, for example contain a lot of oil
- we get cooking oil and margarine from them.
- Seeds also store starch.
- Glucose is turned into lipids (fats
and oils) for storing in seeds.
- Stored as starch
- Glucose is turned into starch and stored in roots, stems and leaves,
ready for use when photosynthesis isn't happening, like the winter.
- Starch is insoluble which makes it much better for
storing than glucose. A cell with lots of glucose in
it would draw in loads of water and swell up.
