Solution
The correct option is A Centrioles
Vacuoles are storage bubbles found in animal and plant cells, but bigger in plant cells. These are used for storage of food or water.
The cell wall is a protective outer covering of the cell. It is mostly present in plant cells. It supports the contents of the cell and protects from pathogen attack and wear and tear. It is made of cellulose, lignin.
The nucleus of the cell contains a majority of the cell's genetic material, i.e., DNA in the form of DNA-protein complex, called as chromatin. It is present in both animal and plant cells.
Animal cells contain centrioles, cylindrical organelles that help in cell division and absent in plant cells. Thus, the correct answer is option D.
