What is the difference between active absorption and passive absorption?

Open in App

Solution

Active absorption & Passive absorption:
The symplast route, which is the transfer of water from cell to cell through the plasmodesmata of the cell, is used for active absorption.

Passive absorption occurs when the root cells are not actively involved in the absorption process and instead rely on the pull of transpiration.
Active Absorption Passive Absorption
Active absorption refers to the absorption of water by roots with the help of adenosine triphosphate, generated by the root respiration: as the root cells actively take part in the process.
The sort of absorption that occurs through the transpiration pull is known as passive absorption.
2. Rate of absorption depends on diffusion pressure deficit (DPD). 2. Tension (force) is created by the transpiration pull, which aids in the upward passage of water into the xylem sap.
3. Energy is required 3. Energy isn't required.
4. The rate of absorption is slow. 4. The faster the rate of transpiration, the greater the water absorption.
5. Absorbed through the symplast pathway and transmembrane pathway. 5. Water passes through the apoplast pathway, symplast pathway and transmembrane pathway.
6. Absorption due to the activity of root hair cells. 6. Absorption due to the activity of the leaves
