What cell does archegonium produce?

What cell does archegonium produce?

What cell is produced in the archegonium? The archegonium matures to produce one egg at the base of the venter cells.

What cell does the antheridium produce?

The antheridium is the male gametophyte and produces sperm cells (male gametes). The antheridium will produce numerous sperm for fertilization. The archegonia are the female gametophyte and will produce egg cells (female gametes). The archegonium will produce one egg at maturity.Mar 10, 2022

What do the archegonia produce?

An archegonium (pl: archegonia), from the ancient Greek ἀρχή ("beginning") and γόνος ("offspring"), is a multicellular structure or organ of the gametophyte phase of certain plants, producing and containing the ovum or female gamete. The corresponding male organ is called the antheridium.

What does the archegonium do?

An archegonium (pl: archegonia), from the ancient Greek ἀρχή ("beginning") and γόνος ("offspring"), is a multicellular structure or organ of the gametophyte phase of certain plants, producing and containing the ovum or female gamete.

Where is archegonium produced?

archegonium, the female reproductive organ in ferns and mosses. An archegonium also occurs in some gymnosperms, e.g., cycads and conifers.

How is archegonium produced?

Neck-canal cells, located above the egg, disappear as the archegonium matures, thus producing a passage for entry of the sperm. The sperm are produced in the corresponding male reproductive organ, the antheridium.

Is the egg in each archegonium produced by mitosis or meiosis?

Each archegonium produces a single egg cell by mitosis. Within each antheridium, mitosis produces many biflagellate (two flagella) sperm.Dec 11, 2015

Where is antheridium produced?

produced in globose structures (antheridia) that are either stalked or sunken in the gametophyte. The antherozoids, always many in number, develop from mother cells enclosed in the jacket of the antheridium.

How is antheridium produced?

Each antheridium produces numerous sperm. The eggs are produced in tiny, typically somewhat flask-like structures called archegonia. Each archegonium holds one egg (in a swollen section called the venter) and the sperm enter through the channel in the narrower, tubular section (or neck).Sep 12, 2012

What cell does antheridium produce?

The antheridium is the male gametophyte and produces sperm cells (male gametes). The antheridium will produce numerous sperm for fertilization. The archegonia are the female gametophyte and will produce egg cells (female gametes). The archegonium will produce one egg at maturity.Mar 10, 2022

Where do the archegonia and antheridia grow?

The archegonia are always found at the arch of the heart, and the antheridia are tucked away among the tiny rhizoids at the other end. The sperm swims to the egg to fuse into a diploid zygote. The new sporophyte grows directly out of the top of the gametophyte.
