Question
Which of the following statement is correct?
- Ratio of surface area to volume controls the cell size.
- Ratio of length to height controls the cell size.
- Ratio of surface area to size controls the cell size.
- None of these
Hint:
Consider cell as a three dimensional unit.
The correct answer is: Ratio of surface area to volume controls the cell size.
- Cells are the structural and functional unit of life
- Cells are so small that cannot be seen with naked eyes
- Cell size is small to enhance the exchange of materials in and out of the cell easily
- Volume and surface volume determine the size of a cell
- Smaller cells are effective for proper exchange of materials and maintaining metabolism
- Large cells either contain larger nucleus to provide nourishment or grow protrusions to enhance the exchange of the necessary materials
