NEET BIOLOGY

Detailed explanation-1: -Essentially all of the water used by land plants is absorbed from the soil by roots. A root system consists of a complex network of individual roots that vary in age along their length. Roots grow from their tips and initially produce thin and non-woody fine roots.

Detailed explanation-2: -While plants can absorb water through their leaves, it is not a very efficient way for plants to take up water. If water condenses on the leaf during high humidity, such as fog, then plants can take in some of that surface water. The bulk of water uptake by most plants is via the roots.

Detailed explanation-3: -All plants absorb moisture from the air, but some are incredibly efficient in doing that. Plants like moist soil thrive in high humidity and are most effective at absorbing water vapor from their surroundings. However, plants that are originally from dry areas that receive little rainfall can also extract moisture.

Detailed explanation-4: -Water and solutes are transported by the xylem from the roots to the leaves, and food is transported from the leaves to the rest of the plant by the phloem. The process by which water evaporates from the leaves and draws more water from the roots is called ‘transpiration’.

Detailed explanation-5: -With the help of the xylem, plants conduct water from the roots to multiple regions of the plant via the ascent of the sap process. Ascent of sap: The ascent of sap and the upward movement of water and minerals from the roots to the top of the plants via xylem are well known.
