Cell Growth and Reproduction Mitosis and Meiosis

Cell Growth and Reproduction Mitosis and Meiosis. 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.

Mitosis

Mitosis

Mitosis. The Cell Cycle. Cells go through a continual process of growth, repair, and division, collectively called the cell cycle Mitosis is merely a small portion of the cell life-cycle Varies cell to cell, but most cells spend approximately 90% of their life in interphase. Interphase.
