  • A cell will swell up if (a) The concentration of water molecules in the cell is higher than the concentration of water molecules in surrounding medium

A cell will swell up if

(a) The concentration of water molecules in the cell is higher than the concentration of water molecules in the surrounding medium

(b) The concentration of water molecules in the surrounding medium is higher than the water molecules concentration in the cell

(c) The concentration of water molecules is the same in the cell and the surrounding medium

(d) Concentration of water molecules does not matter

Answers (1)

Osmosis is the movement of water from a higher concentration to a lower concentration when separated by a semipermeable membrane like a plasma membrane.

The behaviour of a cell in hypertonic solution:

A hypertonic solution is a solution whose water concentration is less compared to the solution inside the cell (cytoplasm). Due to osmosis, water moves out of the cell leading to the shrinking of the cell.

The behaviour of cells in hypotonic solution:

A hypotonic solution is a solution whose water concentration is high compared to the solution inside the cell (cytoplasm). Due to osmosis, water moves into the cell leading to the bulging of the cell.

The behavior of cells in Isotonic Solution

An isotonic solution is a solution whose water concentration is the same compared to the solution inside the cell (cytoplasm). So, the cell stays stable (No change in shape).

Therefore, option (b) is correct.
