Osmoregulation occurs in Amoeba an Paramoecium through

Q. Assertion :Amoeba contains a contractile vacuole. Reason: It helps in both digestion and osmoregulation.

Q. Osmoregulation is essential to all organisms as it maintains homeostasis of the organism's water content.
Osmoregulation in unicellular freshwater organisms like amoebas and paramecia involves an organelle called the contractile vacuole, which collects excess water as it accumulates in the cell and pumps it out. The graphs above plot contraction rate in contractile vacuoles vs. surrounding solution concentrations.
Which of the graphs correctly illustrates the results obtained when Paramoecium is placed in increasingly hypertonic solutions?

Q. The vacuole which helps in osmoregulation is found in_________.

Q. In protozoa, like Amoeba and Paramecium, an organ is found for osmoregulation, which is
