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.

Which generation of mosses are the photosynthetic?
The first generation of mosses starts with germination of spores to develop into gametophyte. The male and female gametophytes produce anthridia and archegonia. Motile antherozoids are released from anthridia and make their way to archegonia through water. The egg inside archegonium is fertilized to form the zygote. The zygote develops into a sporophyte, which remain dependent on the gametophyte.
What do gametophytes produce?
Gametophytes go through mitosis to create gametes (pollen in male gametophyte and egg in female gametophyte)
What do gametophyte produce during a plant life cycle?
The gametophyte produces gametes.
How does the gametophyte generation of a plant differ from the sporophyte generation?
In most plants, the sporophyte generation is dominant. In fern, for example, the fern itself is the sporophyte. This organism produces spores that fall to the substrate below and grow into a separate organism called a gametophyte. The gametophyte produces sperm and eggs in order to produce a new sporophyte which grows out of the gametophyte's body, destroying it. It is important to note that the gametophyte is haploid and the sporophyte is dploid.
In what stage does the plant produce spores?
Plants produce spores during the gametophyte, or haploid, stages. Spores are the sex cells for the plant. The spores will then germinate and produce new plants.
What is the function of an Antheridia?
It produce and contains the male gametes called antherozoids.it is present in the gametophyte phase of a lower plants.

What advance characteristic of sub-phylum Filicinophyta?
One advanced characteristic of the sub-phylum Filicinophyta is the presence of well-developed vascular tissues that allow for efficient transport of water, nutrients, and sugars throughout the plant. Another characteristic is the presence of megaphylls, which are large, flattened leaves with a complex vascular system. Additionally, Filicinophytes exhibit homosporous or heterosporous reproduction, with most species producing spores for reproduction.
What important structures do gametophytes produce?
Anthredia and archegonia
True about the life cycle of mosses?
The life cycle of moss is as follows:Sperm and egg are fertilized and form a zygote. The zygote transforms into a gametophyte and then a sporophyte. It undergoes meiosis and grows to form moss.
What do antheridia produce?
In seedless plants, fungi, and algae it produces sperm
What stage does the plants produce spores?
The gametophyte stage
Spores divide in mitosis to produce what?
Gametophyte generation
The spores that plants produce develop into what?
gametophyte stage
What do gametophytes produce?
Gametophytes go through mitosis to create gametes (pollen in male gametophyte and egg in female gametophyte)
What do gametophyte produce during a plant life cycle?
The gametophyte produces gametes.
Has a water resistant covering and gametophyte parts that can produce sperm?
Pollen grainÊ has a water resistant covering and contains a male gametophyte part that can produce sperm. Sperms are carried as part of the pollen grain by gravity.
