Mention the difference between spermiogenesis and spermiation.

Explanation

### Step-by-Step Solution

1. **Definition of Spermiogenesis**:
- Spermiogenesis is the process in which spermatids, which are immature male gametes, undergo transformation to become spermatozoa (mature sperm). This transformation involves morphological changes that result in the development of a flagellum, condensation of the nucleus, and shedding of excess cytoplasm.

2. **Stage of Spermatogenesis**:
- Spermiogenesis is considered the final stage of spermatogenesis. Spermatogenesis is the entire process of sperm production, which includes several stages: spermatogonia (stem cells), primary spermatocytes, secondary spermatocytes, spermatids, and finally spermatozoa.
