A cell will swell up if
The concentration of water molecules in the cell is higher than the concentration of water molecules in the surrounding medium.
The concentration of water molecules in the surrounding medium is higher than the concentration of water molecules in the cell.
The concentration of water molecules is same in the cell and in the surrounding medium
The concentration of water molecules does not matter.
Which of the following statement marks as a difference between plant cell and animal cell?
Plant cells have cell wall which animal cells do not.
Plant cells do not have vacuole while animal cells do have.
Plant cells have only cell membrane while animal cells have both cell wall as well as cell membrane.
Plant cells have more plastids while animal cells have few plastids.
The process of plasmolysis in plant cell is defined as:
Breakdown of plasma membrane in hypotonic solution.
Shrinkage of cytoplasm in hypertonic medium.
Shrinkage of Nucleoplasm.
None of These
Rahul’s mother was going to make pickle. For this she cut the vegetables into small pieces and put them in the sun for few hours. Rahul was observing all her activities very curiously and asked his mother if why she had put the salted vegetables in the sun. among the following what might be the most appropriate answer for his question?
So that the pickle may get extra flavour.
So that the cut vegetables may absorb the vitamin d as a nutrient from the sun rays.
So that the vegetables may lose all the water by diffusion and evaporation and become dry.
So that the salt may get evenly and properly absorbed by the vegetables.

Movement of solvent molecules from its higher concentration to lower concentration.
Movement of solvent molecules from higher concentration to lower of solution through a permeable membrane.
Movement of solute molecules from lower concentration to higher concentration of solution through a semipermeable membrane.
Anjali wanted to eat rice and kidney bean (rajmah). She requested her mother to cook the same on next day. At night her mother took a cup of kidney beans and put them in a container having some water and the kept the container covered overnight.

(ii) Diffusion
(iii) Endosmosis
(iv) Exosmosis
Only (iii)
Both (i) and (iii)
Both (i) and (iv)
Only (i)
