Mention the differences between spermiogenesis and spermiation.

Explanation

### Step-by-Step Solution:

1. **Definition of Spermiogenesis**:
- Spermiogenesis is the process in which spermatids (immature sperm cells) undergo transformation into mature spermatozoa (sperm cells). This is the final stage of spermatogenesis, which is the overall process of sperm formation.

2. **Process of Spermiogenesis**:
- During spermiogenesis, spermatids undergo morphological changes, including the development of a tail (flagellum), condensation of the nucleus, and formation of the acrosome, which is essential for fertilization. This process results in the formation of motile sperm.
