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?

The correct answer is - Two functions of carbohydrates are structural support and energy storage.

Explanation:

In plants there are normally two carbohydrates are produced are starch and cellulose that have similar molecular structures but their biological function is drastically different.

Cellulose is used as a structural unit of the plant cell wall, its production rates increase during the growth of the plant during spring. starch is a carbohydrate that stores energy reserve that builds up during a sunny time and is consumed during wintery or less sunny days.
