Surface Area to Volume of a Cell

What is the primary function of the cell membrane?

• Storing genetic material

• Regulating the movement of molecules into and out of the cell

• Producing energy for the cell

• Providing structural support to the cell

How does the surface area to volume ratio change as a cell increases in size?

• It increases

• It decreases

• It remains constant

• It fluctuates unpredictably

What is an advantage for a small cell having a large surface area to volume ratio?

• It requires more molecules for metabolic processes.

• Molecules have a shorter distance to diffuse within the cell.

• It produces more waste products.

• It has less cell membrane relative to its volume.

Which of the following is an adaptation cells use to increase their surface area to volume ratio?

• Becoming perfectly spherical

• Developing long extensions

• Increasing their overall volume significantly

• Forming a thick, rigid cell wall
