Starch and Cellulose

The video explains how plants convert glucose into starch for energy storage, primarily in organelles called amyloplasts. Starch is a key energy source for cellular respiration. The video also highlights the structural role of cellulose, which is formed by a slight variation in glucose binding, making it unavailable for energy but essential for plant cell walls.

What is the primary role of starch in plants?

• To provide structural support

• To store energy for future use

• To transport nutrients

• To absorb water
