- When cell grow up, its volume increases much more quickly than the surface area.
- All of the above
Hint:
Cell size and metabolism are interrelated.
The correct answer is: All of the above
- Cell size is determined by surface area and volume
- Typical cell size is less than 100 micrometers
- The small size of cell is required for effective transportation of metabolites and wastes in and out of the cell
- Aging causes the contents of the cells to increase
- The contents of the cell starts to increase from the time a cell has mitotically divided sue to metabolism
