Mendel was an Austrian monk whose researches laid the foundation of genetics. The experiments conducted by Mendel led him to the foundation of two laws which are named as the law of segregation and law of independent assortment.

Answer:
The cellular process of diffusion does not require cellular energy to reach equilibrium.
Osmosis uses a selectively permeable membrane to reach equilibrium.
Explanation:
The process of diffusion in which energy is not required is called passive transport.
Osmosis is also a type of diffusion in which materials pass through a semi-permeable membrane in the cell. Semi-permeable membrane allows certain solutes to pass through such as salts and nutrients etc.
