By swimming in watery fluid through the neck of archegonium the sperm reaches to the egg in seedless plants.
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.
Seed plants produce seeds to overcome the adverse environmental conditions whereas seedless plants overcome the adverse environmental conditions by vegetative parts such as tubers, gemma cups or even spores. Since formation of seed involves genetic advance seed formation for reproduction is more successful in nature.
In pea plants, the eggs are fertilized by pollen. Pollen contains the male gametes (sperm cells) that fertilize the female gametes (egg cells) in the ovule of the flower. This process leads to seed development in pea plants.
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.
A seed is formed when a pollen grain lands on the stigma of the flower, and sends down a pollen tube which releases a sperm cell into the ovule. This fertilization or joining of the sperm cell and ovule forms a cell called a zygote. The zygote then develops into an embryo. The embryo along with the food storage organs, cotyledons and/or endosperm, and the seed coat or testa make up what is called the seed.

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.
In plants, fertilization occurs when one sperm cell from a pollen grain fuses with an egg cell to form a seed. Therefore, only one sperm cell is needed to fertilize one egg cell and produce a seed.
The mobile sexual reproductive parts of seedless plants are sperm cells. These sperm cells are typically flagellated, allowing them to swim through water to reach the egg for fertilization. Seedless plants rely on water for the transfer of sperm to the egg, unlike seed plants which have pollen to transport sperm to the egg.

sperm
After a sperm cell joins with an egg cell in apple trees, a fertilized egg is formed which develops into a seed. This seed contains the genetic material from both the sperm and egg, and when planted, can potentially grow into a new apple tree.
Motile sperm are crucial for the fertilization of egg cells in land plants. They enable the sperm to swim to the egg cell, thereby enhancing the chances of successful fertilization and seed production. This mobility allows for efficient sexual reproduction in land plants, promoting genetic diversity and adaptation.
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.
in almost every female plant there is an ovary chamber that the male flower sperm enters and finds eggs to fertilize. after the egg is fertilized it becomes a seed and the flower "plants" the seed.
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.
