Question

The process by which water enters the root hair cell is _____

Answer 1

Hint: 1) Root hairs, also known as absorbent hairs, are tubular outgrowths of a trichoblast, a hair-forming cell on a plant root's epidermis.
2) These structures are only seldom branched and are lateral branches of a single cell.
3) They are located in the maturation area, also known as the zone of differentiation of the root.

Complete answer
Root hairs, also classified as absorbent hairs, are tubular outgrowths of a trichoblast, a hair-forming cell found on the epidermis of a plant root. These systems are lateral extensions of a single cell and are rarely branched. They are found in the root's maturation region, also known as the zone of differentiation.Osmosis is the process by which plants extract water from the soil. Root hair cells are designed for this by providing a wide surface area to facilitate osmosis. Water is consumed and transferred from the roots to the rest of the plant, where it is used for a variety of purposes: It is a chemical that is used in photosynthesis. Plants can only absorb minerals that are soluble (those that can dissolve in water). From their root hair cells, they ingest minerals dissolved in solution from the soil.

Solution
The process by which water enters the root hair cell is called osmosis. The water reaches root hair through osmosis due to its semipermeability and low potential.

Note
1) Root hair cells range in size from 15 to 17 micrometers in diameter and from 80 to 1,500 micrometers in total.
2) They are only present in the maturation zone, not the elongation zone, presumably because any root hairs that emerge are sheared off as the root elongates and passes through the soil.
3) Root hairs expand at a rate of at least 1m/min, making them especially useful for cell expansion study.
