Minute cells are found in mycoplasma. Mycoplasma is:

Options

A. Virus
B. Fungi
C. Bacteria
D. Green algae

Answer

To answer the question about mycoplasma, we will break down the information step by step.

### Step-by-Step Solution:

1. **Definition of Mycoplasma**:
Mycoplasma refers to a genus of bacteria that are characterized by their small size and lack of a cell wall. They are among the smallest living cells known.

**Hint**: Remember that mycoplasma are unique because they lack a cell wall, which distinguishes them from many other bacteria.

2. **Classification**:
Mycoplasma are classified as bacteria. They are not viruses, fungi, or algae. Specifically, they belong to the class of bacteria known as "Mollicutes."

**Hint**: Focus on the characteristics that define mycoplasma as bacteria, particularly their lack of a cell wall.

3. **Shape and Size**:
Mycoplasma are typically rod-shaped and are known for being minute in size, which is why they are often referred to as "minute cells."

**Hint**: Recall that their small size contributes to their classification and their ability to evade certain types of antibiotics that target cell walls.

4. **Pathogenic Nature**:
Some species of mycoplasma are pathogenic, meaning they can cause diseases in humans and animals. For example, Mycoplasma pneumoniae is known to cause respiratory infections.

**Hint**: Consider how their pathogenicity relates to their structure and function as bacteria.

5. **Cell Structure**:
Mycoplasma have a complex cell membrane but lack a true nucleus. Their genetic material is present in the form of DNA, and they contain ribosomes for protein synthesis.

**Hint**: Pay attention to the structural differences between mycoplasma and other bacteria, particularly regarding their genetic material.

### Final Answer:
Mycoplasma is a genus of bacteria that are characterized by their minute size, lack of a cell wall, and pathogenic potential. They are classified as bacteria and are known to cause various diseases.
