What are the advantages of using insoluble substances such as starch for storage, rather than soluble substances such as glucose
|
|
They do not affect the water concentration inside cells
|
|
|
They do not move away from the storage areas in the plant
|
|
|
Both are correct
|
|
|
Neither are correct
|
Explanation:
Detailed explanation-1: -Plants store energy in the form of starch, instead of glucose, because starch is insoluble. This means that starch will not effect the water concentration inside cells and also it will not move away from the storage areas within the plant.
Detailed explanation-2: -Starch and glycogen are better storage products than glucose because they take up less space as less bulky, and can be hydrolyzed to glucose as needed.
Detailed explanation-3: -This is because glucose and sucrose are both water soluble, which means that they will interfere with the water concentration in cells by increasing the solute concentration. So these sugars have to be stored as insoluble molecules.
