Question : What is the need for plants to have both sexual and asexual means of reproductions? |
Answer» Solution :1] Asexual Reproduction: By asexual reproduction a large number of plants can be produced by a SMALL vegetative part in a short span of time. 2] Genetically identical plants can be obtained by asexual reproduction. 3] Vegetative parts of plants can withstand adverse CLIMATIC conditions and can germinate into a new plant on RETURN of FAVOURABLE conditions. 4] Reproduction through sexual means is uncertain hence asexual means is important. 1] Sexual Reproduction: By sexual methods, plants will have genetic variations which results in higher yields as the plant adapts against all odds. 2] The primary advantage of sexual reproduction is that itencourages the survival of a species. 3] Sexual reproduction creates genetic diversity within a species. 4] In sexual reproduction there is a natural level of disease resistance throughout the species. 5] Genetic VARIATION can lead to evolutionary advancements. |
