What do bryophytes need a film of water for?
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.
Where does fertilization take place 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.
Does bryophytes require water fertilization?
No, angiosperms do not need water to reproduce. Bryophytes, or mosses, need water to reproduce-the sperm cells swim to the egg by following a trail of chemicals in the water. Thus, mosses reproduce in wet, rainy seasons of the year. Angiosperms, on the other hand, do not require water because the stamen releases male gametophytes, pollen grains, that are carried by the wind to the egg in the carpel.
Were the first plants that did not require water for transferring sperm to eggs.?
Gymnosperms
Is the gametophyte not free living in bryophytes?
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.

How do droplets of water relate to bryophyte reproduction?
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 need standing water to do what?
reproduce
Why are bryophytes are called as amphibious plants?
Mosses belong to the division Bryophyta. Bryophytes are generally terrestrial plants but they need water in order to reproduce. As moss is a bryophyte even it is a terrestrial plant which needs abundant moisture for growth and reproduction. So mosses (Bryophytes) are called the amphibians of the Plant Kingdom.
What group of plants require water for sexual reproduction to occur?
Strictly speaking all plants, for without water plants die! However algae, bryophytes (mosses and liverworts) and pteridophytes (ferns) all have motile male gametes which require free water to swim through to the female gamete.
Why water must be present for the bryophytes to complete the sexual portion of the life cycle?
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.
What are the differences between bryophytes and spermatophytes?
differentiate between spermatophytes and bryophytes

Why do gymnosperms do not need water for fertilization?
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.
