Question

The process by which molecules distribute themselves evenly within the spaces they occupy

Answer 1

Diffusion:

• When molecules move randomly along the concentration gradient from an area of higher concentration to an area of lower concentration is called diffusion.
• Diffusion involves the movement of all types of matter namely solids, liquids, and gases.

Significance of diffusion in plants:

• It helps in the absorption and release of gases and other molecules in various chemical processes such as photosynthesis and respiration.
• It helps in the absorption of gases and other molecules from the soil to the roots.

Final answer:

Hence, diffusion is the process by which molecules distribute themselves evenly within the spaces they occupy.
