Answer 1

Answer:

Explanation:

Osmotic pressure:-

• Osmotic pressure is the minimum pressure that must be exerted to prevent the passage of the pure solvent into the solution when the two are separated by a semipermeable membrane.

Active transport:-

• Active transport is the passage of  a substance from its lower to higher concentration, using energy from the cell, through a living cell membrane.

Root pressure:-

• It is the pressure developed in the roots due to continued inward movement of water through cell to cell osmosis which helps in the ascent of sap upward direction through xylem vessels.

Answer 2

Answer:

Osmotic pressure can be defined as the minimum pressure that must be applied to a solution to halt the flow of solvent molecules through a semipermeable membrane (osmosis).

Formula:-

• π = iCRT

where,

• π is the osmotic pressure
• i is the van’t Hoff factor
• C is the molar concentration of the solute in the solution
• R is the universal gas constant
• T is the temperature
