Give an illustration account of reproduction met in lichen
Answers
Answer:
Two forms of reproduction can be found amongst living organisms - sexual and asexual. It is by the mixing of genes from two individuals, via sexual reproduction, that genetic diversity is effected, whereas in asexual reproduction there is no such mixing of genes. Both sexual and asexual reproduction can be found amongst the lichens. When talking of plants (or lichens, which were once thought of as plants) asexual reproduction is commonly called vegetative reproduction. Though lichens, as a whole, may reproduce both sexually or vegetatively, there are species in which both types of reproduction may be common but also species where one type is rare or even unknown. In each form of reproduction propagules of some sort are produced and dispersed and there is a separate page dealing with PROPAGULE DISPERSAL. The SEXUAL VS. VEGETATIVE page gives some general comments about the two means of reproduction.
