Inside the archegonium
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.
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.
Cross-Fertilization!
An egg in a plant does not pass through a pollen tube. In plant reproduction, the egg cell is located in the ovule within the ovary of the flower. The pollen tube allows the sperm cells to travel from the pollen to the egg for fertilization to occur.
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.
If fertilization does not occur, the egg will detach itself and pass through and you will get a normal period.

When pollen is transferred from one plant to fertilize the egg cell of a different plant, it results in cross-fertilization. This process increases genetic diversity and leads to the formation of seeds with different traits. Cross-fertilization can occur through various mechanisms such as wind, insects, birds, or other animals.
