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.
What else can I help you with?
Do bryophytes need water for fertilization?
Yes, bryophytes, like mosses and liverworts, require water for fertilization. This is because they rely on water to transport sperm from the male gametophyte to the female gametophyte for fertilization to occur.
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.
Were the first plants that did not require water for transferring sperm to eggs.?
Gymnosperms
Why must be bryophytes live in places where there is standing water for at least part of the year?
Bryophytes, which include mosses, liverworts, and hornworts, require standing water for reproduction because their sperm must swim through water to reach the eggs for fertilization. Additionally, their tissues lack true vascular systems, making them dependent on moisture in their environment for hydration and nutrient uptake. Living in areas with standing water ensures that they remain hydrated and can successfully complete their life cycle.

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 are bryophytes considered incompletely adapted to the terrestrial environment when compared with other plants?
They require moisture for fertilization to occur. Their sperm are flagellated.
Were the first plants that did not require water for transferring sperm to eggs.?
Gymnosperms
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.
Why r bryophytes called the amphibians of the plant kingdom?
Bryophytes are often referred to as the amphibians of the plant kingdom because they thrive in moist environments and require water for reproduction, similar to amphibians that depend on water for their life cycles. They possess characteristics of both terrestrial and aquatic plants, as they can live on land but need moisture for their gametes to swim during fertilization. Additionally, bryophytes lack true roots, stems, and leaves, resembling early land plants that adapted to terrestrial habitats while still maintaining some dependence on water.
What are the differences between bryophytes and spermatophytes?
differentiate between spermatophytes and bryophytes
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.

How is the mechanism for spore dispersal in ferns similar to that of bryophytes?
Both ferns and bryophytes rely on water for spore dispersal, though the mechanisms differ slightly. In ferns, mature spores are released from sporangia, often aided by wind or raindrops, while in bryophytes, spores are typically released from capsules that can open when wet, allowing for dispersal when conditions are right. Both groups produce lightweight spores that can be carried by air or water to suitable habitats for germination. Additionally, both rely on moist environments for successful reproduction, as their gametes require water for fertilization.
