Question

Bryophytes are dependent on water because
(a) water is essential for fertilization for their
homosporous nature
(b) water is essential for their vegetative
propagation
(c) the sperms can easily reach upto egg in the
archegonium
(d) archegonium has to remain filled with water
for fertilization

Answer 1

Bryophytes are dependent on water because the sperms can easily reach up to egg in the archegonium.

• Option (c) is correct.
• Bryophytes require water for their reproductive phase, as the water is used in maturation and dehiscence of sex organs in bryophytes.  
• Hence the water plays an important role in completing the lifecycle of bryophytes.
• Thus, they are called amphibians of the plant kingdom.

Answer 2

Bryophytes are dependent on water because  the sperms can easily reach up to egg in the  archegonium.

Option (C) is correct.

Explanation:

• The method of reproduction in Bryophytes plants is sexual mode of reproduction.
• The female reproductive organ is called archegonium and male reproductive organ is antheridium.
• The sperms that are formed in male antheridium reach the female archegonium for the process of fertilisation to take place.

Thus Bryophytes are dependent on water because  the sperms can easily reach up to egg in the  archegonium.
