What else can I help you with?
What are some examples of cells that contain flagella?
Bacterial cells, spermatozoa i.e. human sperm cell, green algae, ferns, mosses and some gymnosperms.
Do ferns have swimming sperm?
yes.
What is a structure in seedless plants that produces sperm?
Antheridia are structures in seedless plants that produce sperm. They are typically found on the gametophyte generation of plants like ferns and mosses. Within the antheridia, sperm cells are produced through a process of spermatogenesis.
Structure that holds antheridia and archegonia in ferns?
The structure that holds antheridia and archegonia in ferns is called the gametophyte. It is a small, heart-shaped structure that develops on the underside of the fern frond. Antheridia produce sperm cells, while archegonia produce egg cells for sexual reproduction in ferns.
Explain why ferns live in moist environments even though they have vascular tissue?
This is because the plants relese spores into their surroundings,where they grow into gametophytes. When the gametophtes produce egg cells and sperm cells,there must be enough water available for fertilization. hope my answes correct i too was searching for a long time to find the answer, but when i read again {looks like i found it} ;)
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.
Which groups of plants have flagellated sperm?
Ferns, mosses and some others
How do whisk ferns reproduce?
Whisk ferns reproduce asexually through spores that are produced in sporangia located in the axils of their leaves. The spores are released into the environment, where they can germinate and grow into new gametophytes. Whisk ferns can also reproduce sexually through the fusion of sperm and egg cells produced by specialized structures called antheridia and archegonia.
When does meiosis occur?
Meiosis typically occurs during the formation of reproductive cells (eggs and sperm) in organisms for sexual reproduction. In humans, meiosis happens during the formation of eggs (in females) and sperm (in males) during gametogenesis.
Why ferns live in moist environments?
Ferns live in moist environments to transport water to cells.
How are sperms transferred from the male to the female plantin mosses and in ferns?
In mosses, sperm is transferred from the male gametophyte to the female gametophyte via water, as sperm cells swim through moisture to reach the egg. In ferns, sperm is also motile and relies on water for movement; they swim from the male antheridia to the female archegonia during the process of fertilization. Both processes depend on water, highlighting the need for a moist environment for reproduction in these non-flowering plants.
Can Sertoli cells produce a sperm?
No, Sertoli cells do not produce sperm. They provide support and nourishment for developing sperm cells in the seminiferous tubules of the testes. Sperm cells are produced by germ cells through the process of spermatogenesis.
