Grow larger
|
|
|
Divide into smaller pieces
|
|
|
Either A or B
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -Answer and Explanation: The correct answer is the option: A. A cell’s surface area can be increased by dividing the cell into two smaller pieces.
Detailed explanation-2: -As the radius of a cell increases, its surface area increases as the square of its radius, but its volume increases as the cube of its radius (much more rapidly). Therefore, as a cell increases in size, its surface area-to-volume ratio decreases.
Detailed explanation-3: -Explanation: Prokaryotic cells have internal folding of the cell membrane which are responsible for certain functions like respiration. These foldings increase the surface area.
