This text outlines the stages of the cell cycle: Interphase (G1, S, G2) where cells grow, synthesize DNA, and prepare for division. Mitosis and cytokinesis are also discussed as critical processes for cell division. Additionally, it includes volume and surface area calculations for cubic cells, with examples showing how to compute these properties and their ratios. These calculations demonstrate the relationship between surface area and volume, highlighting their importance in cellular processes and function.

Cell Cycle G1 - growth and cell does job Interphase S - DNA is synthesized G2 - growth of organelles needed to replicate cell Mitosis Cytokinesis
1 cm3 • Volume calculation= l x w x h 1 x 1x 1 = 1cm3 • Surface area calculation= • Area x number of sides (l x w ) x 6 1 x 1 x 6 = 6 cm2 • Ratio Surface area: volume 6 cm2 : 1 cm3 = 6/1 = 6
2 cm3 • Volume calculation= l x w x h 2 x 2x 2 = 8 cm3 • Surface area calculation= • Area x number of sides (l x w ) x 6 2 x 2 x 6 = 24 cm2 • Ratio Surface area: volume 24 cm2 : 8 cm3 = 24/8 = 3
3 cm3 • Volume calculation= l x w x h 3 x 3 x 3 = 27 cm3 • Surface area calculation= • Area x number of sides (l x w ) x 6 3 x 3 x 6 = 54 cm2 • Ratio Surface area: volume 54 cm2 : 27 cm3 = 54/27 = 2
