Question
Below are 4 types of cells (not displayed to scale). Which cell has the largest NC ratio?
- Cheek cell
- Cardiac muscle cell
- Fat cell
- Kidney cell
Solution
To answer this question, we first need to understand what the NC ratio is. The NC ratio refers to the Nucleus-Cytoplasm ratio, which is the size of the nucleus of a cell compared to the size of the cytoplasm.
-
Cheek Cell: These are squamous epithelial cells, and they have a relatively small nucleus compared to the size of the cell, so the NC ratio is low.
-
Cardiac Muscle Cell: These cells are larger and have a single, centrally located nucleus. However, due to the large amount of cytoplasm required for their function, the NC ratio is also low.
-
Fat Cell: Fat cells, or adipocytes, have a small, eccentrically located nucleus. The majority of the cell's volume is taken up by a large lipid droplet, so the NC ratio is very low.
-
Kidney Cell: Kidney cells, or renal cells, have a large, spherical nucleus taking up a significant portion of the cell's volume, so the NC ratio is high.
Therefore, the kidney cell has the largest NC ratio among the four types of cells mentioned.
