What is produced inside archegonia?
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 is found inside archegonia?
The archegonium is the female reproductive organ of bryophytes, ferns and gymnosperms, in which an egg cell is produced, fertilization occurs and the proembryo develops. These plants keep the fertilized egg within the archegonium to protect the sporophyte embryo during its development (Niklas and Kutschera 2010).Jan 8, 2016
What does the archegonia produce?
The gametophyte produces structures known as antheridia and archegonia, which produce the male and female gametes respectively.
What will form inside the archegonia when the sperm fertilizes the egg?
In moss fertilization, when the egg (archegonia) and sperm (antheridia) unite, the result is a cell called the zygote.
What cell is produced in the archegonium?
What cell is produced in the archegonium? The archegonium matures to produce one egg at the base of the venter cells.
What type of cell is produced by an archegonium?
The archegonia are the female gametophyte and will produce egg cells (female gametes). The archegonium will produce one egg at maturity.Mar 10, 2022
Is the cell produced by archegonium haploid or diploid?
The male and female sex organs, the antheridia and the archegonia respectively, are produced on the gametophytic plants. Haploid sperm are released from the antheridia and when a haploid sperm reaches a haploid egg in an archegonium the egg is fertilized to produce a diploid cell.
Is the cell produced by the antheridium haploid or diploid?
An antheridium is a haploid structure or organ producing and containing male gametes (called antherozoids or sperm). The plural form is antheridia, and a structure containing one or more antheridia is called an androecium.
Are the archegonia and antheridia haploid or diploid?
Archegonia is the female sex organ present in the gametophyte which is produced at the leafy apex in sexual reproduction. Antheridia is the male sex organ present in the gametophyte which is also produced at the apex. These are haploid structures.
What cells are produced inside the antheridium?
The sperm-producing organ, the antheridium, consists of a jacket of sterile cells with sperm-producing cells inside. Antheridia may be sunken (as in the families Ophioglossaceae and Marattiaceae) or protruding. They vary in size from those with hundreds of sperm to those with only 12 or so.
