Question

why are cells generally so small? select all of the answers that apply
a. as they grow, their volume increases faster than their surface area.

b. as they grow, their surface area increases faster than their volume.

c. moving nutrients across their cell membranes is more efficient.

d. moving waste materials across their cell membranes is more efficient.

Explanation:

Cells rely on their cell membrane to exchange nutrients and waste with the environment. As a cell grows, its volume increases much faster than its surface area, which limits the membrane's ability to support the larger internal volume. Small cell size ensures a high surface area to volume ratio, making nutrient uptake and waste removal more efficient.

Answer:

A. As they grow, their volume increases faster than their surface area.
C. Moving nutrients across their cell membranes is more efficient.
D. Moving waste materials across their cell membranes is more efficient.
