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.
What are the mobile reproductive parts of all nonvascular seedless plants?
In nonvascular seedless plants, such as mosses and liverworts, the mobile reproductive parts are typically sperm cells. These sperm cells are released from specialized structures called antheridia and require water for mobility to reach the egg cells for fertilization.
Were the first plants that did not require water for transferring sperm to eggs.?
Gymnosperms
Seed plants do not require what for reproduction?
a film of water on the plant for the sperm to reach the egg
How tall are liverworts?
Liverworts can vary in height, with some species growing only a few millimeters tall, while others can reach up to 3-5 centimeters in height. They are small, non-vascular plants that typically grow close to the ground in moist environments.
Why do mosses need water for fertilization?
Mosses depend on water for fertilization because their sperm cells need a film of water to swim to the egg cells. This is necessary for successful fertilization to occur in their reproductive process. Without water, the sperm cells would not be able to reach and fertilize the egg cells.
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.
Why does fertilization in ferns require at least a thin film of water?
Fertilization in ferns requires at least a thin film of water because the sperm cells produced by the male gametophyte need to swim to reach the egg cell in the archegonium. This water allows for the sperm to move through, enhancing the chances of successful fertilization.
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.
What are the mobile reproductive parts of all nonvascular seedless plants?
In nonvascular seedless plants, such as mosses and liverworts, the mobile reproductive parts are typically sperm cells. These sperm cells are released from specialized structures called antheridia and require water for mobility to reach the egg cells for fertilization.

What produces sperm in nonvascular plants?
Nonvascular plants, such as mosses and liverworts, do not produce sperm. They rely on water for the movement of their sperm cells to reach the egg for fertilization.
How hot does steam get when it is produced?
Steam can reach temperatures of up to 212 degrees Fahrenheit (100 degrees Celsius) when it is produced.
How often is a run produced when the first batter reaches base?
Every run produced must have a runner reach first base.
How do you disconnect the ac lines on a 1996 Chrysler Concorde?
Most of them require ac line disconnect tools. The tools reach into the round part and release a spring.Most of them require ac line disconnect tools. The tools reach into the round part and release a spring.
How are sperm cells transported to the archegonia during the life cycle of mosses?
In mosses, sperm cells are transported to the archegonia by water. The sperm cells swim in a thin film of water towards the archegonia, where fertilization takes place. This method allows for the sperm cells to reach the egg cells for sexual reproduction to occur.
Which of the following is true of the life cycle of mosses?
a) The growing embryo gives rise to the gametophyte.b) The sporophyte generation is dominant.c)Spores are primarily distributed by water currents.d) The haploid generation grows on the sporophyte generation.e) Antheridia and archegonia are produced by gametophytes.
