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.
B.
Two functions of carbohydrates are structural support and energy storage
Two functions of carbohydrates are structural support and transferring genetic information
C.
Plants cannot produce carbohydrates when there is no sunlight
D.
Carbohydrates are not necessary for plants to grow

Answer 1

Answer:

B. Two functions of carbohydrates are structural support and transferring genetic information

Explanation:

Carbohydrates are synthesized in green plants, thanks to photosynthesis, in which carbon dioxide (CO2) and water are converted into glycides, with energy provided by light. The energy stored in the glucose molecule during photosynthesis is released in the degradation (catabolism) of glucose, producing water and CO2.

From the point of view of metabolism, the main function of carbohydrates in plant organisms is to provide energy and provide structural support. This can be seen in the question above, because we can see that in spring, when stem growth is at its fastest pace, cellulose production rates increase in some plants, while in months with less sunlight, the level of starch decreases in some plants.
