Prokaryotic cells do not have a nuclear membrane bound around the nucleus

Answer

### Step-by-Step Solution:

1. **Understanding Cell Types**: Begin by recognizing that there are two main types of cells: prokaryotic and eukaryotic.

2. **Characteristics of Eukaryotic Cells**: Eukaryotic cells are characterized by having a well-defined nucleus that is enclosed by a nuclear membrane. They also contain various membrane-bound organelles such as mitochondria, chloroplasts, Golgi apparatus, and endoplasmic reticulum.

3. **Characteristics of Prokaryotic Cells**: In contrast, prokaryotic cells (such as bacteria) lack a defined nucleus. Instead of a nuclear membrane, their genetic material is located in a region called the nucleoid, which is not enclosed by a membrane.

4. **Nuclear Membrane in Prokaryotes**: Since prokaryotic cells do not have a true nucleus, they also do not have a nuclear membrane. Therefore, the statement "Prokaryotic cells do not have a nuclear membrane bound around the nucleus" is accurate.

5. **Conclusion**: The statement is true because prokaryotic cells do not possess a nuclear membrane, as they do not have a nucleus in the same way that eukaryotic cells do.
