Question

डिस्क्राइब द स्ट्रक्चर ऑफ रूट हेयर ​

Answer 1

Answer:

A root hair, or absorbent hair, the rhizoid of a vascular plant, is a tubular outgrowth of a trichoblast, a hair-forming cell on the epidermis of a plant root. They are lateral extensions of a single cell and are only rarely branched. They are visible to the naked eye and the light microscope. They are found only in the region of maturation of the root. Just prior to and during root hair cell development, there is elevated phosphorylase activity.[2] Plants absorb water from the soil by osmosis. Root hair cells are adapted for this by having a large surface area to speed up osmosis. Another adaptation is that, they have a large permanent vacuole.

Answer 2

The structure of root hair is quite suitable for absorbing water from the soil.

1. The root hair represents a large surface area in contact with the soil particle.

2. The minute root hair can penetrate between soil particles and when it comes in contact with soil water, the cell membrane allows efficient entry of water into the root.

3. The cytoplasm and the vacuoles also help in water absorption by osmosis
