Explain how cell size and shape affect the overall rate of nutrient intake and the rate of waste elimination.
Smaller cells have a better rate of nutrient intake and elimination waste. [For more details, see ‘Surface Area to Volume Ratios’ and ‘SA:V and its Impact’] A spherical shape has better overall rate of nutrient intake/ waste elimination as compared to that of a cubical shaped cell, because the distance from the surface to the center of a sphere is uniform overall whereas it is not for a cube.
