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.
What types of plants produces seeds inside of a protective cone?
The ovule present on the ovuleferous scale of the cone produces the seed.
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.
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.
Do conifers seed or fruit?
Conifers produce seeds, not fruits. The seeds of conifers are typically contained within cones, which are the reproductive structures of these plants. The cones protect and disperse the seeds when they are mature.

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 the traits of conifers?
It is a non flowering plant.Conifers are also known as EVERGREEN PLANTS because they remain green throughout the whole year.Conifers are found in colder regions and hilly areas.Conifers have prominent roots and stem.there leaves are long,narrow and needle like.These plants produce seeds but these are not enclosed in fruits i.e., they are naked.Seeds of conifers are present in the form of cone.Vascular tissues i.e.Xylem and Phloem are present in conifers.These are some of the traits of the conifers.

Are conifers 1 celled plants?
yes they are
In oomycetes sexual reproduction takes place in the?
In oomycetes, sexual reproduction typically takes place in specialized structures called oogonia and antheridia. Oogonia produce female gametes called eggs, while antheridia produce male gametes called sperm. Fertilization occurs when sperm from antheridia fertilize eggs in oogonia, leading to the formation of zygotes.

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.
In what way are trees and conifers different?

What is a true statement about conifers?
