Difference Between Root Hair and Stem Hair

The key difference between root hair and stem hair is that the root hair is a unicellular structure developed as an outgrowth of the epidermis, while the stem hair is a multicellular structure that is not an outgrowth of the epidermis. ... Stem exists above the surface of the soil while root exists inside the soil.

Complete answer:

What is the difference between root and stem?

The part of the plant which is present above the surface of the soil is called Stems, while Roots is the part of the plant which is present below the soil surface. Secondly stems arises from the plumule and roots from the radical of the embryo. Most importantly stems possess leaves, but roots do not.

What is special about root hair?

Root hair cells have a very large surface area due to them being very long and having hair like projections. They are also filled with many mitochondria so they are very well specialised for active transport of mineral ions from the soil and into the roots. ...

Why do stems have hairs?

Unlike animal hair, though, trichomes are often living cells. ... Trichomes can be insulating by keeping frost away from leaf cells. They can help reduce evaporation by protecting the plant from wind and heat. In many cases, trichomes protect plants from herbivorous insects that may want to feed on them.

What are the hairs on plants called?

Trichomes (/ˈtraɪkoʊmz/ or /ˈtrɪkoʊmz/), from the Greek τρίχωμα (trichōma) meaning "hair", are fine outgrowths or appendages on plants, algae, lichens, and certain protists. They are of diverse structure and function. Examples are hairs, glandular hairs, scales, and papillae.

What is root hair class9?

Root hairs are tubular extensions of the epidermis that greatly increase the surface area of the root. They are found only in the region of maturation of the root.

Is potato a root or stem?

Potatoes, grown in cooler climates or seasons around the world, are often thought of as roots because they usually grow in the ground. But technically they are starchy, enlarged modified stems called tubers, which grow on short branches called stolons from the lower parts of potato plants.

What are the function of stem and root?

The primary functions of the stem are to support the leaves; to conduct water and minerals to the leaves, where they can be converted into usable products by photosynthesis; and to transport these products from the leaves to other parts of the plant, including the roots.

What are the similarities between stem and root?

Similarity: Both stems and roots contain vascular tissues (xylem and phloem), the circulatory system of the plant. Difference: In herbaceous stems, the vascular tissues are contained in bundles; these bundles sit relatively near the surface of the stem.

Why are root hair cells long and thin?

b) Suggest why root hair cells are long and thin and not short and stubby? More membrane surface area so more water can be taken up by the plant.

What do healthy and unhealthy root systems look like?

What do healthy roots look like? Healthy roots should be white or tan, succulent, and numerous and long enough to hold the soil in the shape of the pot. If any root tips are visible, they should be white. If the roots are brown and crumbly, that means the plant is unhealthy.

Why is a root hair cell shaped like that?

Root hair cells have long projections that increase the surface area that the plant can use to absorb water and minerals.
