Cell Growth

• Surface Area: the amount of 'covering' of the object.
• Volume: the amount of space inside the object.
• To find the surface area, you multiple the L * W * the number of sides.
• To find the volume, you multiply the L * W * H.
• The higher the surface area and the lower the volume is the faster the cell fills up.
• Cells are small because being big to too hard to live.
• Some cell growth limitations are information crisis and traffic problems.
• Information Crisis: too many demands placed on DNA.
• Traffic Problems: the volume grows too fast relative to surface area, moving nutrients and waste inefficient.
• Some large cells have unusual structures to maintain a high surface area to volume ratio.
