Morphology (out-look)

  • Fern consists of feathery leaves.
  • The plant body is differentiated into roots, stem and leaves. The roots and stem are underground and only the leaves are aerial.
  • Fern plant is classified under Pteridophyta division because they contain feathery leaves.
  • Roots are generally called rhizoid. They absorb water and mineral from thesoil.
  • The stem is underground. It is covered by brown-hairy structures. These structures are called raiment (young leafs).
  • The leaves are called fronds. Each leaf contains thelarge number of dark-brown structures under the surface. These are called sori (singular: sorus).

The leaves which contain sori are called sporophyll and the leaves which do not contain sori are called tropophyll.



  • Fern belongs to the division Pteridophyta because they have the feathery leaf.
  • Ferns grow in cool places where shade is predominant.

Very Short Questions

During the gametophytic generation, antheridia produce antherozoids. The archegonia produce ova. Archegonia release mallic acid that attracts antherozoids. This movement of antherozoids due to the release of chemical mallic acid by archegonia is called chemo taxis.

Classification of fern plant:
Kingdom : Plant
Sub-kingdom: Cryptogams
Division : Pteridophyta

The leaves of fern plant bear feathers. So, it is kept under pteridophyta. The word 'Pterido' means feather and 'Phyta' means plant. The leaf of fern plant looks like feathers.

Nowadays fern is classified at Tracheophyta due to the presence of well-developed vascular bundle i.e. Xylem and phloem. It means, the transportation of water and minerals absorbed by the root is done by xylem and the food prepared by the leaves is carried away by the well-developed phloem. Besides they have well-developed roots, stem and leaves.

In the life cycle of the fern plant, the plant itself is the sporophyte, which produces spores. On the other hand, the prothallus is the gametophyte, which bears the male and female gametes, antheridia and archegonia respectively.

In fern, sporangium is found at the back of the leaf.

The spores are found on the backside of the leaf of fern plant.
