Fern Matagenesis: Definition & Process

The definition of ferns is equipped with characteristics and we will describe its metagenesis in a simple way so that you can easily understand it. For further discussion, please see the explanation below.

fern plant metagenesis

Metagenesis is the alternation of the life cycle between a generation that reproduces sexually and another generation that reproduces asexually.

However, in general, these two generations have different morphologies from each other. To clarify and increase our insight, let’s look at the following review of the metagenesis of ferns.

Definition

The definition of ferns is a group of plants that have a true vascular system (Tracheophyta), although these plants never produce seeds to reproduce. Ferns are also known as ferns or ferns. In English this plant is known as ‘fern’.

This plant can live all over the world, this plant can not live in snow. Although reproduction does not use fruit or spread flowers, plants can live only by buds.

There are about 12,000 species of this plant in Indonesia and Malaysia. There are so many species that are scattered and can grow in various regions. If you visit the forest or travel to the forest, you will find a lot of this plant. Although in the forest but this plant is not dangerous.

Characteristics of Nail Plants

  • Has good transport vessels in roots, stems, and leaves.
  • Generally, ferns are known for their leaves that grow, from curled shoots and have fine hairs.
  • Uses spores to reproduce, and does not produce flowers and fruit.
  • Able to reproduce vegetatively by forming gemsand reproduce sexually by the fusion of male and female gametes.
  • The body shape of this plant can be like a tree that is usually unbranched, a shrub, an epiphyte, floating in water, vines, hydrophyte or it can be a herb with rhizomes that spread on the ground or humus.
  • Generally, most of the ferns live in the wet tropics.

fern plant metagenesis

Based on the metagenesis chart above, we can draw conclusions about the metagenesis that occurred in this plant, including:

  • Metagenesis in ferns begins with spores, then forms a prothallus or prothallium (gametophyte in large numbers).
  • After that in the next stage the gametophyte will be divided into two, namely the archegonia which will then become the egg cell, and the antheridium which will then become the spermatozoid.
  • Then the egg and spermatozoa will form several zygotes in a number that can be considered quite large.
  • The next stage is to become a sporophyte and then will form sporangium in numbers that can be considered large as well.
  • The last is the spore stage, which in the metagenesis cycle the nail will rotate as in the schematic diagram above.
