Question

The phenomenon of absorption of water that depends on water loss from aerial parts of plants (Transpiration) is
A.Active absorption
B.Passive absorption
C.Both passive and active absorption
D.None of the above

Answer 1

Transpiration is the misfortune of water from a plant within the shape of water vapour. Water is ingested by roots from the soil and transported as a fluid to the leaves through xylem. Within the takes off, little pores allow water to elude as a vapour.

Complete answer:
Transpiration is the method of water development through a plant and its dissipation from airborne parts, such as clears out stems and blooms. Water is fundamental for plants but as it were a little sum of water taken up by the roots is utilized for development and digestion system. The remaining 97–99.5% is misplaced by transpiration and guttation. Passive assimilation is characterized as the assimilation of water without the coordinate consumption of metabolic vitality. Transpiration, the vanishing of water, primarily, through stomata, comes about in the creation of water holes that are filled by detached retention of water by the roots, too alluded to as transpirational pull.

The three major sorts of transpiration are
(1) Stomatal Transpiration
(2) Lenticular Transpiration and
(3) Cuticular Transpiration.
Transpiration primarily takes place through the surface of take off. Transpiration happens through youthful or developed stem is called Cauline transpiration.

Hence, the correct answer is option (B)

Note: Transpiration has two primary capacities: cooling the plant and pumping water and minerals to the clears out for photosynthesis. Plants have to cool themselves for a few reasons. The stomata (pores) must open to require in carbon dioxide for photosynthesis (particularly critical on mornings of sunny days).
