Question

Why do bryophytes plants grow in land but need water for fertilization because of which they are called amphibian plants?

Answer 1

Hint: The liverworts, hornworts, and mosses make up the hypothetical taxonomic division Bryophytes, which includes three non-vascular land plant groups: liverworts, hornworts, and mosses. They are typically small and prefer damp surroundings, however they can thrive in drier ones as well. About 20,000 plant species make up the bryophytes.

Complete answer:
Because flagellated sperm must swim to the non-motile egg to fertilize it, bryophytes require water for sexual reproduction. It would also require water to swim.

The plant kingdom's bryophytes are commonly referred to as amphibians. Amphibians are organisms that can live on both land and water.
Although bryophytes grow in soil, they require water for sexual reproduction. Bryophyte sperm are flagellated, but their eggs are not. There are two flagella on each sperm. As a result, water must be delivered to sperm in order to fertilise them. So that sperm can swim to the egg and fertilise it by whipping their flagella in the water.

Amphibians are organisms that can live on land as well as in water. Plants called bryophytes are nicknamed frogs of the plant kingdom because they live in soil yet need water to reproduce asexually.

They are primarily found in marshy and wetlands areas, where they have adapted to thrive on both water and soil nutrients. In bryophytes, asexual reproduction is the most common way of reproduction.

It happens as a result of the creation of spores. Despite the fact that bryophytes live on land, they require water to fertilise. With the help of their flagella, bryophyte sperm swim through water to the eggs. As a result, bryophytes are classified as plant amphibians.

Note:-
Hornworts reproduce sexually by transferring sperm from the male sex organ (antheridium) to the female sex organ through water (archegonium). A fertilised egg develops into an elongate sporangium in the female sex organ, which splits lengthwise as it grows, releasing the spores that have grown within it.
