Question

Diffusion occurs readily in _____.

(liquids/solids)

Answer 1

Diffusion:

• It is a process in which the molecules of gases, liquids, and solids move freely from a region of higher concentration to a region of lower concentration.
• Diffusion is responsible for the exchange of gases during various processes like photosynthesis, respiration, etc. in plants.
• It also helps in the exchange of nutrients and other chemicals through the cell membrane of the plant cell.

Liquids:

• The molecules of the liquid are loosely packed in comparison to that of solids.
• The higher the space between the molecules the higher the kinetic energy.
• Therefore, due to greater kinetic energy molecules of liquid travel at a higher speed than solids hence, passes quickly through the membranes of plant cells.

Final answer:

Diffusion occurs readily in liquids.
