Question

antheridium and archegonium are haploid sex organ s​

Answer 1

Answer:

True.

The female sex organ in non-flowering plants is the archegonium; archegonia is the plural form.

Explanation:

Archegonium

The female sex organ in non-flowering plants is the archegonium. The plant will usually have more than one archegonium, so we refer to them collectively as archegonia. You can identify the archegonia on a plant because it is shaped a lot like a flask. Let's make sure we know the type of flask we are talking about here. Archegonia are shaped like the flask you use in a laboratory and not the one from which you drink a beverage.

Archegonia are anchored to the gametophyte, from which they developed from by a foot. A gametophyte is the haploid gamete producing form of a plant. Above the foot, is a larger, wider area that looks like the bulb part of a flask. This is called the venter. The venter is the location where the female gamete or egg will be produced and developed. Leading up from the venter is the neck of the archegonium. The archegonium has to mature before the neck is ready to do its function. The neck starts out being full of cells, making it a solid structure. Once the archegonium matures, the cells in the inner portion of the neck will breakdown and form a passageway to the egg.

The archegonium also serves as the site of fertilization. After the egg is fertilized, the egg will remain in the archegonium until it develops into a sporophyte. A sporophyte is the spore producing form of the plant. The archegonium releases the sporophyte once it has fully developed.

Antheridium

The male sex organ in non-flowering plants is called an antheridium. The antheridium looks a lot like a short, thick, globular or cylindrical sac. The antheridium sac looks thick because it consists of several layers of sterile cells that act as a jacket surrounding the inner spermatogeneous tissue. Spermatogeneous tissue is tissue that contains numerous sperm-producing cells. The antheridium is also anchored down to the gametophyte just like the archegonium.
