Uses of Glucose
The glucose produced by photosynthesis is mainly used for respiration in plants. However, it can also be converted into other products:
Starch
- Starch is insoluble (cannot be dissolved) and is stored in stems, leaves or roots.
Cellulose
- Cellulose is used to strengthen cell walls. It is particularly important for fast-growing plants.
Fats and oils
- Fats and oils are stored in structures such as seeds.
- For example, sunflower seeds are a key ingredient in cooking oils.
Proteins
- Proteins are needed for cell growth and repair.
- A source of nitrogen is also needed for glucose to be converted into proteins.
- Plants get this nitrogen by absorbing nitrate ions (minerals) from soil.
