which organelle is present in the cells of a mouse but not
present in the cells of a bean plant?
a. cell wall
b.
chloroplast
c. cell membrane
d. centriole

Centriole

Explanation:

Centriole is the only cell organelle which is found in the animals cell but not in plant cell. The centriole is a cylindrical organelle which is composed mainly of the protein known as tubulin.

They are mostly found in the eukaryotic cells. It is absent in the plant cell.The centrioles are very important for the cell division and they produce microtubules which gets separated into two identical cells.

Hence, the correct answer is option D

The cell organelle that is present in the cells of a mouse but not in the cells of a bean plant would be the centriole. The correct option would be D.

Plant cells such as the ones in a bean plant have cell wall, chloroplast, and cell membrane. However, centrioles are only found in animals cells.

Centrioles in animal cells such as the one in a mouse functions as the basal bodies of spindle fiber, cilia, and flagella from which the spindle apparatus springs from during mitotic cell division. The spindle apparatus helps to organize microtubules during the mitotic process.

Plant cells have rigid cell walls that can organize microtubules during mitotic divisions. Hence, centrioles are not needed.
