Question

why are root hairs called ephemeral?​

Answer 1

Answer:

Ephemeral, in botany, any short-lived plant, usually one that has one or more generations per year, growing only during favourable periods (as when adequate moisture is available) and passing the unfavourable periods in the form of seeds.

Answer 2

Roots hairs are called ephemeral because they are short-lived.

• The root hairs are formed by the process of elongation. The cells that undergo elongation are epidermis cells.

• The roots hairs appear more like a long tubular structure that grows outside the main root and due to the presence of these hairs, the surface area is increased.

• Root hairs are important for plants because it helps in the process of absorption of water and minerals from the soil.

• Through these root hairs, plants can form symbiotic relationships with microbes.
