Some plants have mobile gametes: mosses, liverworts, ferns, and these can travel through moist soil under their own power. Most plants however require some active agent to carry their pollen for them. In the case of conifers and grasses this agent is the wind. Most angiosperms use insects: mites, flies, bees, beetles and such. A few use hummingbirds, bats, and honey bears.
What else can I help you with?
Were the first plants that did not require water for transferring sperm to eggs.?
Gymnosperms
What life cycle components appear only in mosses and ferns?
The gametophyte generation is more prominent and independent in mosses and ferns compared to seed plants. Also, the sporophyte generation in mosses and ferns is not as prominent or long-lived as in seed plants. Finally, mosses and ferns rely on water for fertilization, a characteristic not seen in seed plants.
Why do seedless plants require liquid water for reproduction?
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.
What are the mobile sexual reproductive part of all seedless plants?
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.
How does pollen help a seed plant reproduce without water?
Pollen is the male reproductive structure of seed plants. It contains the sperm cells necessary for fertilization. When pollen is transferred from the male reproductive structure to the female reproductive structure (such as by wind or pollinators), it can reach the ovule without the need for water, allowing for fertilization and seed formation to occur.
What does fertilization not require in most seed 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.

How is fertilization in seed plants differ fertilization in seedless plants?
i dont think this question is appropriate for the answer
How does fertilization in a seed plants differ from fertilization in seedless plants?
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.
Why do seedless plants require liquid water for reproduction?
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.
What you call seed producing plant?
It is called a seed plant, not to be confused with ferns and mosses whose gametes require water for fertilization. Seed plants can be either gymnosperms or angiosperms.Spermatophyte

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.
Why don't gametophytes or gametes of seed plants need standing water to function?
Gametophytes of seed plants do not need standing water to function because they produce male and female gametes within protective structures (pollen grains and ovules) that are transferred by wind, insects, or other means for fertilization. This adaptation allows seed plants to reproduce successfully in a variety of environments, not relying on standing water for the fertilization process.
What are characteristics of seed plants?
Seed plants are characterized by the presence of ovules and pollen grains and after pollination and fertilization produce seeds from their ovules.
What is the reaction of ferns when pollen stays on it?
Ferns do not produce pollen; instead, they reproduce via spores. When spores land on a suitable environment, they can germinate and develop into a gametophyte, which eventually leads to the formation of new fern plants. If pollen from seed plants accidentally lands on a fern, it has no effect, as ferns and seed plants reproduce through entirely different mechanisms. Ferns rely on water for fertilization, specifically for sperm to swim to the egg cell, while pollen is a feature of seed-producing plants.
How do plants produce seed pods?
All leguminous plants produce seed pods form their ovaries after pollination and fertilization of egg inside ovules.
