What organelle allows a cell to exceed normal cell size limitations, and how does it accomplish this?
The central vacuole enlarge as the vacuole absorbs water, enabling the cell to become larger with a minimal investment in new cytoplasm
What is the effect of cell growth on the surface area/ volume ratio (what is the relationship between these two?
As a cell grows in size, its surface area grows proportionally less than its volume.
Do cells maintain a HIGH or LOW surface area/ volume ration?
Smaller cell= higher surface to volume ratio. The surface area to volume ratio gets smaller as the cell gets larger.
How is surface area calculated and how is volume calculated?
Surface Area: A=4x3.14r^2 Volume: V=4/3x3.14r^3
