Column A Column B (a) Zygote (v) Embryo The zygote is a diploid cell formed by the fusion of male and female gametes. It undergoes mitotic division to form the embryo. Column A Column B (b) Bird Pollination (iii) Red silk cotton The transfer of pollen grains from the anther to the stigma of the pistil of the flower is called pollination. In most of the plants, pollination takes place with the help of pollinating agents. In red silk cotton, pollination takes place with the help of birds. Column A Column B (c) Clone (ii) Genetically identical offspring The clones are the product of asexual reproduction. These are morphologically and genetically similar to their parent. Column A Column B (d) Isogamy (i) Monocystis Isogamy is the fusion of morphologically similar gametes. This type of fusion takes place in a protozoan, Monocystis. Column A Column B (e) Bisexual animal (v) Earthworm In some animals, both male and fema le sex organs a re present in the same individual. This type animal is called bisexual animal or hermaphrodite animal. Earthworm is an example of such type of animals. It can produce both male and female gametes by a single parent.
