Why do plants store food as starch instead of glucose?
Answers (1)
The plants convert excess glucose into starch for storage purposes due to the following reasons:
- Glucose is very soluble in water. Large levels of free glucose held by plants would cause water to rush into the cells (osmosis), therefore damaging or bursting them. Starch, on the other hand, is a huge, insoluble substance not cause this issue.
- Stability and Safety: Stored in great quantities, glucose is chemically active and may react chemically with other molecules within the cell. Long-term storage calls for starch as it is more inert and stable.
- Starch consists of numerous glucose units joined together as an energy reserve. Enzymes may break down the starch back into glucose when the plant requires energy. The plant therefore has a readily available reserve of energy when needed.
