archegonia's Usage Examples:

An archegonium (pl: archegonia), from the ancient Greek ἀρχή ("beginning") and γόνος ("offspring"), is a multicellular structure or organ of the gametophyte.

archegonia occur on the same plant and those in which they occur on different plants.

The term monoicous may be used where antheridia and archegonia occur.

gametophyte complete with female sex organs, or archegonia.

The oocytes were fertilized in the archegonia by free-swimming flagellate sperm produced by.

They are found between clusters of archegonia and antheridia.

bearer of the sex organs (gametangia), the female archegonia and the male antheridia.

If both the archegonia and antheridia are arranged at the same plant.

female (producing archegonia and hence egg cells).

Monoicous: each individual gametophyte produces both antheridia and archegonia and can function both.

(singular antheridium) and the egg-producing ones archegonia (singular archegonium).

Antheridia and archegonia occur on the same gametophyte, which is then.

The term gynoecium is also used by botanists to refer to a cluster of archegonia and any associated modified leaves or stems present on a gametophyte shoot.

Antheridia and archegonia are often clustered.

A cluster of antheridia is called an androecium while a cluster of archegonia is called a gynoecium.

gametangia are most commonly called archegonia.

Eventually, plants with archegonia were found, which resembled the archegonia found in mosses.

asexual; it can also reproduce sexually (see illustration) with four archegonia arranged in a cross-shaped head (hence the specific name cruciata) bearing.

produced in antheridia and archegonia by mitosis.

The sperm released from the antheridia respond to chemicals released by ripe archegonia and swim to them in.

Megagametophytes produce archegonia (lost in some groups such as flowering plants), which produce egg cells.

antheridia (male) and archegonia (female) by mitosis.

The sperm released from the antheridia respond to chemicals released by ripe archegonia and swim to them.

individual plants producing either antheridia or archegonia, but never both.

The female plants (with archegonia) are typically ten times the size of the male.

end in a cup-shaped structure bearing gametangia, both antheridia and archegonia, but little structural information is preserved at the cellular level.

Plants are usually monoicous, and sexual reproduction is by antheridia and archegonia.

Eggs develop in archegonia and sperm in antheridia.
