Bryophytes, such as mosses and liverworts, need a film of water for reproduction. The sperm of bryophytes require water to swim to the egg for fertilization, as they do not have specialized structures for pollen transfer like flowering plants. Additionally, water helps in the dispersal of spores for reproduction in bryophytes.
In bryophytes, fertilization typically takes place in the archegonium, which is the female reproductive structure. The sperm swims through water to reach the egg inside the archegonium, where fertilization occurs.
Yes, bryophytes require water for fertilization as they rely on water for sperm to swim to eggs for fertilization to occur. Water is essential for this process in bryophytes because it helps in transporting the sperm to the egg.
Gymnosperms
In bryophytes, the gametophyte is the dominant, free-living stage of the life cycle. It is the structure responsible for producing gametes and supporting fertilization. The gametophyte in bryophytes usually grows independently from the sporophyte, which is dependent on the gametophyte for nutrition and support.

Droplets of water are essential for bryophyte reproduction as they help in the dispersal of sperm to reach the egg for fertilization. In some bryophytes, water droplets can also aid in the dispersal of spores for reproduction. This dependency on water for reproduction is a key characteristic of bryophytes due to their need for a moist environment.

Bryophytes are called amphibious plants because they can survive in both aquatic and terrestrial environments. They can grow in moist habitats like bogs, streams, and wetlands, but also adapt to drier conditions by going dormant until moisture returns. This dual ability to thrive in both land and water gives them the amphibious characteristic.
Nonvascular plants, such as mosses and liverworts, require water for sexual reproduction to occur. This is because they produce sperm cells that need to swim through water to reach the egg cells for fertilization.
Water is needed for bryophytes to complete the sexual portion of their life cycle because it allows the motile sperm to swim to the egg for fertilization. This process requires a water medium for effective sperm movement to reach the egg.
Gymnosperms
Oh, dude, like bryophytes are like the OG plants, you know, they're the mosses and liverworts, they don't have seeds or vascular tissue, they're like the hipsters of the plant world. Spermatophytes, on the other hand, are like the popular kids with seeds and all, they're the gymnosperms and angiosperms, they're all about that vascular tissue and reproduction game. So, yeah, the main difference is like bryophytes are the old school cool and spermatophytes are the new kids on the block with all the fancy features.
In bryophytes, the gametophyte is the dominant, free-living stage of the life cycle. It is the structure responsible for producing gametes and supporting fertilization. The gametophyte in bryophytes usually grows independently from the sporophyte, which is dependent on the gametophyte for nutrition and support.
Gymnosperms do not need water for fertilization because their male gametes are carried by pollen grains, which can be transported by the wind. This allows for fertilization to occur without the need for water.
