answer

hi i think its because glucose is soluble so it would affect the water balance of cells but starch is insoluble so it doesn't affect the water balace of the cells

Glucose will be difficult to

Glucose will be difficult to be stored in the plant cells as it is soluble in water or in the cytoplasm. The more concentration of glucose in the cytoplasm will imbalance the osmotic pressure of the cytoplasm. Starch is insoluble in water so it can be stored in the cells.
Glucose is the source of energy which gives energy for all cell functions.
Respiration provides plant with energy to carry on all other living activities
hope i helped you xx

Because glucose is soluble in water and would therefore affect the way water moves into and out of the cells. Lots of glucose stored in plant cells could affect the water balance of the whole plant.

Starch is insoluble in water. It will have no effect on the water balance of the plant.This means plants can store large amounts of starch in their cells.
