Plants store extra sugar as
A
starch
B
cellulose
C
glycogen
D
glucose
Explanation: 

Detailed explanation-1: -Glucose is easily soluble in water, therefore, plants store glucose in the form of insoluble starch in leaves, root tubers, fruits, etc. Plants utilise this stored starch as a source of energy for life activities and prepare substances that are required for their growth.

Detailed explanation-2: -Plants store glucose in the form of starch. Starch is made up of many glucose molecules all linked together. Plants build starch using their excess glucose, and then they store it to be used later.

Detailed explanation-3: -Animals store excess sugar in the form of glycogen. Plants store excess sugar in the form of starch.

Detailed explanation-4: -In plants, glucose is stored in the form of starch, which can be broken down back into glucose via cellular respiration in order to supply ATP.

Detailed explanation-5: -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.
