True or False statements

The surface area of a cell is determined by the surface area of the plasma membrane, the selective boundary through which materials enter and exit the cell. Blank
target 1 of 5
As a cell increases in size, the surface area increases proportionately more than the volume. Blank
target 2 of 5
A cell's growth is limited by its surface area to volume ratio. Blank
target 3 of 5
A small surface area to volume ratio is desirable for the cell to transport enough nutrients and waste across the plasma membrane to meet its metabolic needs. Blanktarget 4 of 5
Multicellularity in large organisms results in more, smaller cells and thus a higher surface area to volume ratio. Blank

Answer 1

Here are the answers to your True or False statements:

1. **The surface area of a cell is determined by the surface area of the plasma membrane, the selective boundary through which materials enter and exit the cell.**
**True**

2. **As a cell increases in size, the surface area increases proportionately more than the volume.**
**False**
(As a cell increases in size, the volume increases at a faster rate than the surface area, leading to a decrease in the surface area to volume ratio.)

3. **A cell's growth is limited by its surface area to volume ratio.**
**True**
(A low surface area to volume ratio means that a cell may not be able to transport enough materials to meet its metabolic needs as it grows larger.)

4. **A small surface area to volume ratio is desirable for the cell to transport enough nutrients and waste across the plasma membrane to meet its metabolic needs.**
**False**
(A large surface area to volume ratio is desirable because it allows for more efficient transport of nutrients and waste.)

5. **Multicellularity in large organisms results in more, smaller cells and thus a higher surface area to volume ratio.**
**True**
(Multicellular organisms consist of many smaller cells, which collectively provide a higher surface area to volume ratio compared to a single large cell.)
