The terms 'nucleolus' was coined by

Options

A. Bowman
B. Fontana
C. Flemming
D. Leeuwenhoeck

Answer

**Step-by-Step Solution:**

1. **Understanding the Nucleolus**:
The nucleolus is a small, dense, spherical structure found within the nucleus of a cell. It plays a crucial role in the production of ribosomes and is visible during the interphase of cell division under a microscope.

**Hint**: Remember that the nucleolus is not just any structure; it is specifically involved in ribosome production.

2. **Composition of the Nucleolus**:
The nucleolus is dense due to the presence of DNA, RNA, and proteins. These components are derived from specific chromosomal regions known as nuclear organizing regions.

**Hint**: Focus on the materials that make up the nucleolus and their origin.

3. **Historical Context**:
The term "nucleolus" was coined by a scientist named Baumann. However, it is important to note that the structure was first described by another scientist, Fontana, in the year 1781.

**Hint**: Distinguish between who coined the term and who first described the structure.

4. **Final Answer**:
The term "nucleolus" was coined by Baumann, while Fontana first described it in 1781.

**Hint**: Keep in mind the difference between coining a term and describing a discovery.
