Question

What two conditions are necessary for osmosis to take place

Answer 1

Answer:

conditions required for osmosis are:

• presence of a concentration gradient ,the solution separated by a semi permieable membrane should have different concentration.
• presence of a semi permeable membrane.

Answer 2

Answer:

The conditions required for osmosis are:

Two solutions having different solute concentration.

A semi-permeable membrane.

Explanation:

• When two solutions having different concentration of solutes is separated by a semi-permeable membrane, the solvent moves from the region of high concentration of solvent ( low concentration of solute) to the region of low concentration of solvent (high concentration of solute). This phenomenon is known as Osmosis.
• This phenomenon happens because molecules tend to move from a region where its concentration is high to a region where its concentration is low.
• This is how root hairs take in water from the soil.
