Answer:

Hello!

Sexual Reproduction has slightly different stages in plants and animals. Sexual reproduction in plants has the following steps:

  1. Pollination
  2. Gamete germination
  3. Fertilization
  4. Zygote Formation

Sexual reproduction in animals has the following steps:

  1. Gamete formation
  2. Fertilization
  3. Zygote formation
  4. Zygote develops into embryo

Advantages:

  1. The embryo develops in a protective environment i.e. the ovary in plants and uterus in animals.
  2. Sexual reproduction produces genetic variations in the offspring that aid survival and incur resistance to diseases.

Explanation:

* Pre-fertilization stages include meiosis 1 and 2 that involve the formation of genetically different gametes.

* The stages, zygote formation and the development of the zygote into an embryo and later into an individual, are classed as post-fertilization stages.
