What are the differences between passive and active absorption?

Question

Accepted Answer

Basis of differentiation

Passive absorption

Active absorption

Definition

Is the absorption regulated by transportation without the activity of root hair

Is the absorption of water via the activity of plant root hairs

Energy

Does not require energy

Energy is required

Rate of absorption

Absorption rate is faster

Is relatively slower

Structures involved

Involves the apoplast and transmembrane pathway

Involves the symplast and transmembrane pathway

Transpiration

Is dependent on transpiration

Is not dependent on transpiration

Water level

Typically occurs when the water level is low in the soil

Typically occurs when the water level is high in the soil

Types

No such classification

Two types:

Active osmostic water absorption
Active non-osmotic water absorption
