Explanation

(a) Saprotrophic Fungi are multicellular organisms whose mode of nutrition is saprotrophic, or saprobic. They absorb nutrients from dead plant and animal matter, excreta, etc. By releasing digestive enzymes in them.
Some fungi are parasitic and cause diseases. Ringworm is a skin infection caused by a fungus, while smut is a fungal crop disease. Some fungi, are mutualistic or symbiotic. They absorb nutrients from their partners and help them too, e.g., certain fungi associated with algae. (lichens).
(b) Chitin Fungi are achlorophyllous, heterotrophic and eukaryotic organisms. Their cell wall is made up of rough, complex sugar called chitin, or fungal cellulose.
(c ) Lichens Some fungal species live in permanent mutually dependent relationship with blue-green algae (or cynobacteria). Such relationships are called symbiotic and these symbiotic life forms includes lichens.
(d) Carbohydrate Chitin is a modified polysaccharide that contains nitrogen. Chitin may be described as cellulose with one hydroxyl group on each monomer, chemically known as N-acetyl glucose mine.
Species A species is one of the basic units of biological classification and a taxonomic rank. It includes minimum number of organisms with maximum number of similar characters.
(f) Thallophyta Plants without well differentiated stem, root and leaf are kept in Thallophyta.
(g) Bryophytes Bryophytes are called amphibians of plant kingdom as they can survive on both land and water.
