Cell Growth and Reproduction

Cell Growth and Reproduction. Surface area to Volume Ratio. A cell is 2mm x 2mm x 2mm What is its surface area? What is its volume?. Surface area: 2*2*6= 24mm2. Volume 2*2*2= 8mm3. Surface area :Volume Ratio 24:8 = 3:1. What happens to the ratio of SA:V as the cell gets larger?.

Mitosis

Mitosis. The cell cycle. Mitosis is only one section of the life cycle of a cell. Interphase is the main part of the cell cycle. This is where DNA is replicated (a copy is made) to prepare for mitosis. Overview of mitosis. Interphase. Most of the cell cycle is spent in interphase.
