Gymnosperms
a film of water on the plant for the sperm to reach the egg
Seedless plants require liquid water for reproduction because they depend on the movement of sperm to reach the egg for fertilization. In the absence of seeds, water helps to disperse the sperm to reach the egg for fertilization to occur, as these plants do not rely on pollination by wind or animals.
if your using Plato then the answer is D. the movement of sperm between plants.
In nonvascular seedless plants, such as mosses and liverworts, the mobile reproductive parts are typically sperm cells. These sperm cells are released from specialized structures called antheridia and require water for mobility to reach the egg cells for fertilization.

In the absence of seeds, water helps to disperse the sperm to reach the egg for fertilization to occur, as these plants do not rely on pollination by wind or animals.
Fertilization in most seed plants does not require swimming sperm, as they are transported within pollen grains and delivered directly to the plant ovule for fertilization to occur. This eliminates the need for water as a medium for fertilization, unlike in non-seed plants or aquatic plants where swimming sperm are necessary to reach the egg.
Seedless plants require the liquid water because the sperm has to swim to reach the egg. This is in contrast to most seed plants, that fertilize using pollen transferred by wind or insects.

They require moisture for fertilization to occur. Their sperm are flagellated.
In nonvascular seedless plants, such as mosses and liverworts, the mobile reproductive parts are typically sperm cells. These sperm cells are released from specialized structures called antheridia and require water for mobility to reach the egg cells for fertilization.
plants do not produce sperm, they produce pollen
Nonvascular plants, such as mosses and liverworts, do not produce sperm. They rely on water for the movement of their sperm cells to reach the egg for fertilization.
