Large Sized And More Lysosomes Are Present In :

A: Erythrocytes
B: Kupffer's Cells
C: Endocrine Gland Cells
D: Epithelial Cells

The answer is: B

Explanation

B: Kupffer's cells are the cells with the largest size and the most abundant lysosomes. Kupffer cells are a type of macrophage found in the liver that play a critical role in removing foreign substances and pathogens from the blood. These cells have a high phagocytic activity and are responsible for breaking down red blood cells, bacteria, and other debris that they encounter. The high concentration of lysosomes in Kupffer cells is necessary to facilitate this function.

A: Erythrocytes (red blood cells) do not have lysosomes at all.

C: Endocrine gland cells are not typically associated with large lysosomes.

D: Epithelial cells may have lysosomes, but the size and abundance of these lysosomes are not typically as significant as those found in Kupffer cells.
