Question

question 2 (mandatory) (2 points)
the size of a cell is limited by the

a) lack of building materials
b) size of the organism
c) relationship between the volume of the cell and its surface area
d) job it does
e) materials it has to exchange

question 3 (mandatory) (2 points)
cell shape is reinforced by

a) phospholipids
b) dna

Explanation:

For Question 2, as a cell grows, its volume increases faster than its surface - area. The surface - area to volume ratio affects the cell's ability to exchange materials with the environment, thus limiting cell size. For Question 3, the cell shape is reinforced by the cytoskeleton, but among the given options, phospholipids form the cell membrane and contribute to cell structure and shape to some extent.

Answer:

Question 2: C. relationship between the volume of the cell and its surface area
Question 3: a. phospholipids
