Detailed explanation-3: -To reproduce sexually, pollen from the male part is transferred to the female part by air or other flying animals, where fertilization occurs to form a seed. This seed will germinate and grow to become a new plant. There are two types of pollination namely: Self-Pollination – This fertilization is with the same flower.

Detailed explanation-4: -When a male gamete and a female gamete are involved in reproduction, this method is referred to as sexual reproduction. Here the male and female gametes fuse during fertilization to produce a single-celled zygote. The zygote subsequently develops into an embryo which further develops into a new individual.
