Question:

In which form do plants store energy?

a. starch

b. glycogen

c. chitin

d. cellulose

Expert Verified Solution:

The correct answer is a. starch.

Plants primarily store energy in the form of starch. Starch is a complex carbohydrate that plants synthesize through photosynthesis. It serves as a way for plants to store excess glucose, which can be broken down and used for energy when needed.

Here’s a brief overview of the options:

Starch (a): This is the correct answer. Starch is a polysaccharide made up of glucose units and is used by plants to store energy.

Glycogen (b): This is the primary energy storage form in animals, not plants. It is also a polysaccharide made of glucose, but it is stored mainly in the liver and muscles.

Chitin (c): This is a structural polysaccharide found in the exoskeletons of arthropods and insects, not used for energy storage in plants.

Cellulose (d): This is a major component of plant cell walls, providing structural support. It is not used for energy storage.
