Question

Suppose you plant a seed and observe that a tree of large mass grows from it. The tree achieves a final mass that changes very little for years afterward. Which of the following is true about the tree?

A. Both anabolic and catabolic reactions took place in the seed and tree when it was young and growing, but then all reactions stopped when the tree reached a stable mass.
B. Both anabolic and catabolic reactions took place in the seed and tree when it was young and growing, and both continue now even though the tree reached a stable mass.
C. Only anabolic reactions took place in the seed and tree when it was young and growing, and only catabolic reactions continue now that the tree reached a stable mass.
D. Only catabolic reactions took place in the seed and tree when it was young and growing, and only anabolic reactions continue now that the tree reached a stable mass.

Answer 1

both anabolic and catabolic reactions took place in the seed and tree when it was young and growing, and both continue now even though the tree reached a stable mass.

Answer 2

The correct answer is statement B.

Step-by-step explanation:

Food gets dissociated due to an array of reactions known as catabolism. The catabolic reactions or catabolism refers to an array of metabolic pathways, which breaks down food molecules into basic units, which are either used in other anabolic reactions or get oxidized to discharge energy. On the other hand, the anabolic reactions or anabolism refers to an array of metabolic pathways, which produces molecules from smaller units. In the given case, both the catabolic and anabolic reactions occurred in the seed and tree at the time of its development, and both persist in the similar manner even when the tree has attained a stable mass.
