Amoeba proteus is a unicellular organism that inhabits freshwater ponds and streams. At its largest size, Amoeba proteus can be visible to the naked eye.
State how the surface area to volume ratio changes as the Amoeba proteus grows.
Gaseous exchange allows the Amoeba to carry out aerobic respiration.
State which aspect of the surface area to volume ratio has the greater effect on the rate of gaseous exchange.
The contractile vacuole of the Amoeba helps to maintain its osmotic equilibrium by excreting excess water from the cell.
State which aspect of the surface area to volume ratio would depend on this organelle.
