The upcoming discussion will update you about the difference between passive absorption and active absorption.
Difference # Passive Absorption:
1. This processes physical driving force, which is non-metallic.
2. This type of absorption of ions and molecules is spontaneous and proceeds towards equilibrium.
3. Such absorption of a-substance occurs across a protoplasmic membrane from its higher to lower chemical potential.
4. In passive absorption, the energy yielding metabolic processes are not involved.
5. The passive transport takes place through the protoplasmic layer in between the cell wall and the vacuole.
Difference # Active Absorption:
1. Here, the driving force is energy derived from metabolic processes.
2. This type of absorption is not spontaneous and does not proceed towards equilibrium.
3. The active absorption of a substance occurs across a protoplasmic membrane from its lower to higher chemical potential, i.e., against concentration gradient.
4. When energy yielding metabolic processes are weakened, active transport system is also checked.
5. The active transport takes place across the protoplasmic membrane (i.e., plasme membrane, tonoplast, etc.).
