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.


What are moss egg cells produced by?

Moss egg cells are produced by the female reproductive organs called archegonia in moss plants. The archegonia are responsible for producing and releasing the egg cells, which are then fertilized by sperm cells to form a zygote.


What plants have a prothallus that forms archegonia and antheridia and has a dominant sporophyte?

Ferns are plants that have a prothallus with archegonia and antheridia. In ferns, the sporophyte generation is dominant, meaning it is the more visible and long-lived stage of the plant's life cycle compared to the gametophyte stage.


Where are the moss egg cells produced?

Moss egg cells, also known as archegonia, are produced in the reproductive structures called gametangia, which are located at the tips of the gametophyte plant body. These gametangia develop on the female moss plants, and each gametangium contains an egg cell.


Where are the females gametes produced in nonvascular plants?

Female gametes in nonvascular plants are typically produced in structures called archegonia, which are located on the female gametophyte (the haploid stage of the plant). Archegonia contain the egg cell and are designed to receive and nurture the male gametes for fertilization to occur.

What are Female gametangia called?

Archegonia


Are archegonia haploid or diploid?

Archegonia are haploid structures found in plants. They are part of the female reproductive structure and are responsible for producing the egg cells.

Archegonia


Where are moss eggs cells produced?

archegonia


Why is it advantageous for the antheridia and archegonia to be located on the underside of the prothallus?

Having antheridia and archegonia on the underside of the prothallus protects them from desiccation and mechanical damage, as they are closer to the substrate. This positioning also aids in the dispersal of sperm towards the eggs when water is present, as water carries the sperm to the archegonia.

The female reproductive structure of nonvascular plant is called?

archegonia.


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.


What is the difference between antheridia and archegonia?

Antheridia are male reproductive structures that produce sperm cells, while archegonia are female reproductive structures that house egg cells. Antheridia are typically smaller and simpler in structure compared to archegonia. Both structures are commonly found in plants like mosses and ferns.


Which of the following plants has a prothallus that forms archegonia and antheridia and has a dominant sporophyte?

Flowering Plants.


Do vascular plants produce antheridia and archegonia on the same gametophyte?

Only in those cases where spores are not differentiated into micro- & megaspores for developing the gametophytes. Thus homosporous vascular plants produce archegonia and antheridia on same gametophyte.
