The amount of nutrients needed is determined by ____
|
|
The cell’s volume
|
|
|
The cell’s surface area
|
|
|
The cell’s Rough ER

|
|
The cell’s Smooth ER
|
Explanation:
Detailed explanation-1: -Cell size is limited by the surface area to volume ratio of the cell. As the volume of a cell increases, it becomes harder to efficiently transport materials in and out of the cell.
Detailed explanation-2: -The cytoplasm represents a cell’s volume.
Detailed explanation-3: -The smaller the cell, the more favorable the ratio of volume to surface area for material exchange with the atmosphere is done by diffusion. Although surface area determines the rate at which nutrients are taken in or excreted, the volume determines how much enters and leaves the cell.
