(ii) In seed plants, pollen grains are the carriers of male gametes and ovule have the egg. (iii) Events in sexual reproduction before the formation of zygote are called post-fertilisation events. (iv) Sexual reproduction involves the formation and fusion of gametes, (v) Animals are categorised into oviparous and viviparous based on whether the development of the zygote takes place outside the body of the female parent or inside.
