Question

why does posterior contractile vacuole of paramecium pulsatile faster than anterior one ?

Answer 1

Answer:

Contractile vacuoles are responsible for osmoregulation, or the discharge of excess water from the cell, according to the authors of "Advanced Biology, 1st Ed." (Nelson, 2000). Depending on the species, water is fed into the contractile vacuoles via canals, or by smaller water-carrying vacuoles.
