Question

Why are mosses and liverworts unable to complete their sexual mode of reproduction in dry condition?

Answer 1

because bryophytes mainly requires water for their fertilisation, but if there was dry so there will no chance of sexual reproduction..

Answer 2

Answer:

The sperms of mosses and liverworts need water to swim to eggs.

Explanation:

Liverworts and mosses are non-vascular plants and do not have completely developed transportation systems. They can only survive in water or marshy areas.

The water serves as a transport medium for flagellates (sperms of bryophytes) to swim towards the eggs. In dry condition, there will be no water to carry sperms to eggs, and these plants fail to reproduce sexually.
