Question

E explain briefly the common mode of reproduction in Angiosperms

Answer 1

In angiosperms or flowering plants, there are several modes of reproduction. Generally, they are arranged in two large groups of reproduction:

(i) Asexual or Vegetative

(ii) Sexual types

a) In Asexual or Vegetative Reproduction, the offspring are produced from the somatic cells, while in sexual reproduction there is fusion of male and female gametes.

In the case of vegetative reproduction, any part of the plant, like stem, root or leaf, is capable of growing into a new plant, in addition to performing its sexual functions. Sometimes, in certain plants, buds and bulbils are developed, which develop into new plants.

b) In Sexual Reproduction, the gametes from male and female organs of the flower are fused to produce a zygote. In angiosperms, these organs are generally called, androecium and gynoecium, respectively.

c) In some plants, certain special modes of reproduction are found, which are commonly known as parthenogenesis, sporophytic budding, polyembryony, apomixis, apospory, and micro- propagation. The production of synthetic or artificial seeds is also possible through Tissue Culture.
