Gametangia: The Importance of Reproductive Structures for Sexual Reproduction in Plants and Fungi

What are gametangia?

The haploid cells at the tips of hyphae, created during mitosis

Gametangia are specialized structures found in some groups of plants, such as mosses, liverworts, ferns, and fungi. They are the organs that produce and contain gametes, which are male and female reproductive cells necessary for sexual reproduction.

Gametangia have protective structures that prevent the gametes from drying out or being washed away. In mosses and liverworts, male gametangia are referred to as antheridia and produce motile sperm while female gametangia are called archegonia and produce an egg. In ferns, both male and female gametangia are grouped together in structures called sporangia. The male gametangia produce small, multiflagellate sperm while the female gametangia produce an egg.

In fungi, gametangia may be formed by individual hyphal cells that differentiate into male or female structures known as “gametangia,” or sexual organs. The fusion of these structures leads to the formation of a zygote, which develops into a new individual.

Overall, gametangia are important reproductive structures that facilitate sexual reproduction in many groups of plants and fungi.
