ALL CELLS ARE NUCLEATED EXCEPT:
- A- LYMPH
- B- MONOCYTES
- C- RBCS***
- D- NEUTROPHIL.
The correct answer is C- RBCs (Red Blood Cells).
Here's why:
- Most cells in the body contain a nucleus, which houses the genetic material (DNA).
- However, red blood cells are an exception. They mature from nucleated cells but lose their nucleus in the final stages of development. This allows them to carry more oxygen by freeing up space for hemoglobin.
- All other options are examples of nucleated cells:
- Lymph:
It is a fluid that contains lymphocytes, monocytes, and other cells, all of which have nuclei.
- Monocytes:
These are white blood cells with large, single nuclei.
- Neutrophils:
These are also white blood cells with multi-lobed nuclei.
Therefore, only red blood cells are non-nucleated, making them the exception in this group.
