Question

Plants contain the carbohydrates starch and cellulose. In the spring when stem growth is at its fastest rate, cellulose production rates are increased in some plants. In the months with less sunlight, the level of starch decreases in some plants. What does this information demonstrate? A. Carbohydrates are not necessary for plants to grow. B. Plants cannot produce carbohydrates when there is no sunlight. C. Two functions of carbohydrates are structural support and energy storage. D. Two functions of carbohydrates are structural support and transferring genetic information.

Answer 1

Explanation:

Although starch and cellulose are both carbohydrates (and with similar molecular structure), their biological function is drastically different. Cellulose is used by the plant to create the cell walls, is a structural carbohydrate (that is why its production rates increase when the plant is growing, the new cells need cellulose). On the other hand, starch acts as an energy reserve that builds up during sunny months and is consumed during wintery ones
