Mosses (Group 1)

Key characteristics of mosses:
  • Can be classified according to tissue structure (Non Vascular)
  • Can be classified according to seed structure
  • Can be classified according to stature



  1. -Mosses have only a single set of chromosomes and are haploid。
    -In some mosses, green vegetative structures called gemmae are produced on leaves or branches, which can break off and form new plants without the need to go through the cycle of fertilization. This are means of asexual reproduction.
    -Mosses are found chiefly in areas of dampness and low light.

  2. 1) They commonly grow close together in clumps or mats in damp or shady locations.

    2) They do not have flowers or seeds, and their simple leaves cover the thin wiry stems.

    3) At certain times mosses produce spore capsules which may appear as beak-like capsules borne aloft on thin stalks.
