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.

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.
How sexuall reproduction occur in bryophytes?
In bryophytes, sexual reproduction occurs through the release of sperm and eggs. The sperm swims through a film of water to reach and fertilize the egg, forming a zygote. This zygote then develops into a new sporophyte generation.
What process characterizes sexual repoduction?
Sexual reproduction involves the fusion of genetic material from two individuals to produce offspring with genetic variation. It typically includes meiosis, the formation of gametes (sperm and egg cells), fertilization, and the development of a new organism. This process promotes genetic diversity within a population.
What are the differences between species that require sexual reproduction and species that require asexual reproduction?
ones a hore and the others not
Do single-celled organisms reproduce by sexual repoduction?
no
What advantage might asexual repoduction by fission have over sexual reproduction?
C
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 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?

What are the reproductive structures of bryophytes called?
The reproductive structures of bryophytes are called gametangia. These structures produce the gametes (sperm and egg) necessary for sexual reproduction in bryophytes. Gametangia are typically found at the tips of the gametophyte plant.

Can environment influence sexual orientation?
not the orientation but the behavior
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 to sexual reproduction?
the offspring will have the ability to survive in the environment
