Fertilization in Funaria occurs in water only
Funaria is a type of moss that requires water for its reproduction. The reason for this is that fertilization in Funaria occurs in water only. Let us understand this in detail:
Gametophyte stage: Funaria has a haploid gametophyte stage, which is the dominant stage of its life cycle. The gametophyte stage produces male and female sex organs called antheridia and archegonia respectively.
Antheridia: The antheridia produce haploid sperm cells, which are released into the surrounding water.
Archegonia: The archegonia produce haploid egg cells, which are retained within the archegonia.
Fertilization: The sperm cells swim through the water and reach the archegonia, where they fuse with the egg cells to form a diploid zygote. This process of fusion of male and female gametes is called fertilization.
Water requirement: The water is necessary for the movement of sperm cells from antheridia to archegonia. Without water, the sperm cells cannot move, and fertilization cannot occur.
Thus, Funaria requires water for fertilization because its sperm cells are motile, and they need water to move from antheridia to archegonia for fertilization to occur.

Fertilization of Funaria occurs in water. The antherozoids are released into water where they swim and reach archegonium. An antherozoid fuses with the egg to produce the zygote. Thus an external layer of water is essential for the swimming of male gametes to the archegonia.
