Are Antheridia present in conifers?
Yes, antheridia are present in conifers. They are the male reproductive structures that produce sperm cells. In conifers, antheridia are typically found within the male cones of the tree.
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.
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.
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.
What are the gametes produced in nonvascular plants?
These two other answers are straight cap. The correct answer is Antheridium for A+ people.
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.
Where do you Find antheridium?
Antheridia are found in non-flowering plants, particularly in bryophytes (like mosses and liverworts) and certain ferns. They are typically located on the male gametophyte, where they produce sperm cells. Antheridia can be found in moist environments, as they require water for sperm motility during reproduction.
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.
Gametophytes have gamete-producing organs called?
Angiosperms produce seeds in layers of tissue called fruit.
How does sexual reproduction take place in oedogonium?
female reproductive organ oogonia &male antheridia fertilized zygot meotically devid &produce zoospore they germinate new plant of oedogonium
What important structures do gametophytes produce?
Gametophytes typically produce gametes through the process of mitosis. These gametes are necessary for sexual reproduction as they unite to form a zygote, which develops into the sporophyte generation. Additionally, some gametophytes also produce specialized structures such as antheridia and archegonia that house and protect the gametes.
The sperm of a moss is produced within the structure called the?
