Question

which are ephemeral structures in the roots​

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

The ephemeral structure is something that has a very short life expectancy or lasts for a very short period of time. An example of ephemeral is a plant blossom that only lasts for one single day.

In botany, an ephemeral plant structure can be characterized as one that has at least one or more generations every year, growing only in favorable periods and passing the ominous periods as seeds. A few species' seed coats contain a development inhibitor that could only be washed away by a lot of water, stopping germination after a short shower.
