Question

state in sequence four main steps of sexual reproduction and write two advantages of such reproduction

Answer 1

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.

Step-by-step 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.
