Differentiate between gametogenesis and embryogenesis.

Explanation

### Step-by-Step Solution:

1. **Definition**:
- **Gametogenesis**: This is the process of formation and development of gametes (sperm and eggs). The term "gameto" refers to gametes, and "genesis" means formation.
- **Embryogenesis**: This refers to the development of an embryo from a fertilized egg (zygote). The term "embryo" indicates the early stage of development, and "genesis" again means formation.

2. **Origin**:
- **Gametogenesis**: Gametes are produced from diploid cells known as meiocytes (or germ cells).
