Question

What are antheridia and archegonia?

Answer 1

Antheridia:

1. The male sex organ, Antheridia, is a haploid structure that produces male gametes known as antherozoids or sperms.
2. A sterile jacket surrounds a high number of cubic spermatozoic sperm mother cells in an antheridium.
3. Cryptogams male gametes, also known as sperms, are motile, which means they need water to fertilize.

Archegonia:

1. The female sex organ, archegonia, produces female gametes primarily in cryptogams.
2. It is in charge of producing female gametes, which are egg cells or ova.
3. A flask-shaped structure on a short stalk is known as an archegonium.
4. It is divided into two sections: A venter canal cell and an egg cell are enclosed by the venter.
5. The neck is made up of six vertical rows of neck cells that surround the neck canal cells.
6. The ovum is usually not motile at all.
7. To enter the archegonia, motile male gametes typically swim through water films.
