- How Plants Use Glucose
- For Respiration
- 1) Plants manufacture glucose in their leaves.
- 2) They can then use some of the glucose for respiration.
- 3) 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.
- 4) To produce some of these substances they also need to gather a few minerals from the soil.
- Making Cell Walls
- Glucose is converted into cellulose for making strong cell walls especially in fast growing oplants
- Making Proteins
- Glucose is combined with nitrate ions (absorbed from the soil) to make amino acids which are then made into proteins
- Stored As Starch
- Glucose is turned into starch and stored in the roots, stems and leaves ready for use when photosynthesis isnt happening.
- Starch is insoluble which makes it easier to store than glucose a cell with lots of glucose would draw in lots of water and make the cell swell up.
- Potato and parsnip plants store a lot of starch underground over the winter so a new plant can grow from it the following spring. we eat the swollen storage organs.
- Stored In Seeds
- Glucose is turned into lipids for storing in seeds.
- For example: sunflower seeds contain a lot of oil we get cooking oil and margarine from them.
