The correct answer is:
bryophytes
Bryophyta is a group of plants which have gametophytic haploid thalloid body. The motile male gametes are produced in special male reproductive structures called antheridia.
These gametes need thin film of water to swim and reach the female reproductive organ called archegonia. Pteridophytes, gymnosperm and monocots show higher level of organisation.
