In cold or dry conditions a plant may convert glucose into osmoprotectants to help cells tolerate stress.
When plants need quick energy for active transport or growth, they break down glucose by respiration.
Starch is the typical form in which many plants store glucose in leaves and roots.
Excess glucose in seeds and fruits is often stored in a form that is high in energy for the seedling.
If a plant converts glucose into amino acids it needs to absorb another mineral from the soil.
To test whether a leaf has stored glucose as starch, students use iodine solution which turns starch blue-black.
Glucose is stored in plant cells so it is available when photosynthesis is not happening.
During germination, a seed uses stored glucose to supply energy for growth before it can photosynthesise.
When light or CO2 is in short supply, plants may convert excess glucose into starch to save it for later when conditions improve.
If a plant transports glucose as sucrose, it can deliver both carbon and energy to growing roots and shoots.
Glucose is used to make lipids in plants; these lipids are especially important in seeds as energy reserves.
