Question

The following models show one large cell (A) and four small cells (B) Which of the following states why one of the models is better for moving more nutrients in and out of the cell?
A. A has many more pores per volume than
B. A has a bigger volume than B.
C. B has a total volume bigger than A.
D. B has smaller cells but more surface area than A.​

Answer 1

Answer:

D). B has smaller cells but more surface area than A.​

Explanation:

The movement of nutrients in the cells of model B would be better as compared to the cell of model A and the key reason is that 'model B has more  surface area than A despite having smaller cells.' As we know, the surface area of the cell plays a vital role in determining its efficacy in transporting the nutrients through indirect processes like diffusion as it helps in transporting the nutrients without using energy. But if the surface area is less, the flow of nutrients require more direct and active which may consume energy. Since, model B has more surface area, it will transport effectively. Hence, option D is the correct answer.
