Protozoans are actually

Options

A. Cellular
B. Acellular
C. Unicellular
D. Multicellular.

Answer

**Step-by-Step Solution:**

1. **Understanding Protozoans**: Protozoans are classified as eukaryotic organisms that belong to the kingdom Protista. They are primarily single-celled organisms.

2. **Cell Structure**: According to the cell theory, a cell is defined as the functional and structural unit of life. For protozoans, their entire body is made up of a single cell.

3. **Classification of Protozoans**: Even though protozoans are made up of one cell, they do not fit the traditional definition of unicellular organisms. This is because the single cell of a protozoan constitutes its whole body, making it more complex than just a simple unicellular organism.

4. **Terminology**: The term "a cellular" is used to describe protozoans because they do not have multiple cells. Instead, they exist as a single, complete unit that performs all necessary life functions.

5. **Conclusion**: Therefore, the correct classification for protozoans is "a cellular," as they are not considered unicellular in the strictest sense, nor are they multicellular.

**Final Answer**: Protozoans are actually a cellular.
