Question

The water available to plant from Hollard is called
A. Chresard
B. Echard
C. Gravitational water
D. Hygroscopic water

Answer 1

Hint: Hollard is the amount of water present in the field it measures the moisture of the plant.

Complete answer: The water available to plants for consumption which is capillary water is known chresard.
Echard is the water that is not available for consumption to the plant.
Whereas gravitational water is the water that presents in a thin film surrounding the soil particles. To stay alive all living organisms need to transport materials like food, water, and oxygen to various parts of the body.
Food and oxygen are transported to all the cells in the body for respiration and growth.
Waste products are transported from the cells to organs that excrete them.
There are various methods by which materials are transported in plants and animals.
Water and mineral salts dissolved in water enter the plant through the thin root hair present in the roots.
Root hair is outgrowths from the layer of outer cells of the root.
The root hair increases the surface area of the root for the absorption of water and mineral.

So the correct option is ( A )

Note: Types of soil water
1. Gravitational water: free water moving down due to gravity
2. Hygroscopic water: water held tightly by soil particles
3. Capillary water: water held by capillary forces
4. Combined water: water chemically bond to soil water
