Natasha put a plant cell and an animal cell of similar size in two similar dishes containing the same amount of water overnight. The next day, she observed the cells under the microscope and noticed that the animal cell has burst and the plant cell looked more bloated. She drew the following conclusions:
(i) The animal cell has only a thin layer of cell membrane. When too much water enters it, it bursts.
(ii) Plant cell has cell wall made up of cellulose which is very strong material and prevents the cell from bursting.
(iii) The plant cell contains vacuole and therefore can absorb more water.
(iv) The animal cell does not possess vacuole.
Which of the above given conclusions are correct?

A(i) and (ii)
B(iii) and (iv)
C(i), (ii) and (iii)
DAll of these
