Bryophyta: Features, Classification and Economic Importance.
General characters of Bryophytes. Bryophytes are primitive land plants that grow on moist shady places. They prefer moist, cool and shady places to grow. Few of them grow in water and others in bogs, moist walls, rocks and tree trunks. Though they started land life, they require presence of water to complete their life cycle for movement of motile male gametes (antherozoids). They are.
Bryophytes are generally small (less than 5 cm) but some can grow up to a length. of 70 cm (e.g. Polytrichum, Dawsonia). In contrast to vascular plants, they rarely grow. as single stems but in.

Economic Importance of Bryophyta. Ecological Importance. Bryophytes are of great ecological importance. They usually grow densely and hence act as soil binders. Such vegetation also checks soil erosion by reducing the impact of rain drops and wind. Liverworts and mosses, growing on rocks, add organic matter to the substratum after their death.
In some Bryophytes, male and female sex organs are borne on separate gametophytes. Such species are said to be dioecious. In contrast, when a single plant carries both male and female sex organs the species is said to be monoecious. The sex organs are typically borne in clusters, often surrounded by sterile hairs. These may also be borne in a head on a stalk in some species. At maturity, the.
Problems in the Origin and Classification of Bryophytes with Particular Reference to Liverworts ELLA O. CAMPBELL Department of Botany and Zoology. Massey University. Palmerston North (Received 3 August 1970) SUMMARY The origin of bryophytes remains a problem. Special features which are of importance in classification of the group are the clonal.
Bryophytes Bryophytes are terrestrial plants. They mostly grow in moist and cold habitats. Some species can grow in dry places. But they depend on moisture for the reproductive stage. Bryophytes have world wide in distribution. They are found in t.
