Why do bryophytes require a moist environment for sexual repoduction?
Wiki User
∙ 8y ago
when the fern spore falls to the ground, it doesn't begin to grow fronds right away. Instead, the spore grows into a tiny heart - shaped plant called a prothallium. The prothallium does not look like a fern frond at all. If you observe closely, you may find prothallia growing in damp, shady places where there are ferns.

∙ 13y agoferns must live in moist areas, because they have vascular tissues. Vascular tissues give support to fern and transport water through out the whole entire body.
Wiki User
∙ 13y agoYes and no. Ferns need to live in a moist environment in order for the sperm to be able to swim to the egg and fertilize it.
Wiki User
∙ 13y agoBecause they reproduce by spores; water is an important to the development of germinated spore

∙ 12y agoThey need water to reproduce so the sperm is able to swim and fertilize the egg.

What process characterizes sexual repoduction?
Meiosis I and Meiosis II
What advantage might asexual repoduction by fission have over sexual reproduction?
C
Is the hippo able to pass on variation to offspring?
Yes, any animal that undergoes sexual repoduction can pass on variation to their offspring, provided that variation is contained in the gametes, or germinative cells.
What are the differences between species that require sexual reproduction and species that require asexual reproduction?
ones a hore and the others not
What is an advantage of sexual repoduction?
Sexual reproduction creates variaty that asexual reproduction cannot provide. If we were all asexual, that means that there are very little variaty(the little part is caused by mutation) and that we would all look alike and be alike. The problem with this is that if a disease spreads in the population that is lethal to one person, then it will be lethal to everyone in that population(unless there was a mutation). Our being able to reproduce sexually has made it easy to not die by a disease that might be lethal to one person.
Do single-celled organisms reproduce by sexual repoduction?
no
What process characterizes sexual repoduction?
Meiosis I and Meiosis II
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?
The male sex cells,androcytes of bryophytes are motile and require a medium to swim in to reach the female sex organ for fertilisation.Hence water is essential as it becomes the medium for the androcyte to swim.
What is the purpose of sexual repoduction?
Well to make babies and the babies grow up to adults and make more babies to become adults and so on. that's how you were born.
Is the hippo able to pass on variation to offspring?
Yes, any animal that undergoes sexual repoduction can pass on variation to their offspring, provided that variation is contained in the gametes, or germinative cells.
Can environment influence sexual orientation?
not the orientation but the behavior
What is repoduction?
A reproduction, such as a painting, is an attempt to create an exact or near exact copy of the original.
What is an advantage to sexual reproduction?
the offspring will have the ability to survive in the environment
What are the differences between species that require sexual reproduction and species that require asexual reproduction?
ones a hore and the others not
Why do people get sexual confuse?
People do get sexually confused because of the environment they live in and the environment surrounding their early childhood.
