Question

Mummy has put some gram in a tumbler and poured some water on it in the night. In the morning she saw
that gram seeds has swollen up. Can you say why this has happened?
A)O because of osmosis
B)O because of turgor pressure
C) because of diffusion
D) because of transpiration

Answer 1

Answer:

option c easy next reason it was in night

Answer 2

The correct answer is Option A, Osmosis.

• When grams are placed in a tumbler containing water overnight, they absorb water and swell up by a process known as Osmosis.
• Osmosis is the diffusion of water molecules through a semipermeable membrane from a region of higher water concentration to a lower concentration.
• The peas swell up until they become turgid.
• It is the movement of "free" water molecules'.
• It is a colligative property i.e depends only on the concentration of the solute and is independent of the composition and chemical identity of the solute.
• It is a vital process in all biological systems because of the semipermeable nature of the biological membranes and water as the major solvent in these systems.
