Explanation:
Animal cells and plant cells are the two main types of eukaryotic cells. While they have many similarities, there are also some key differences between them. One of the main differences is the presence or absence of certain organelles and structures. In this case, the correct answer is option D - all of these are not present in animal cells.
Plastids:
Plastids are specialized organelles found in plant cells. They are responsible for various functions such as photosynthesis, storage, and the synthesis of pigments. Plastids include chloroplasts, which contain chlorophyll and are involved in photosynthesis. Animal cells do not have plastids, so option A is correct.
Large vacuoles:
Vacuoles are membrane-bound organelles found in both plant and animal cells. However, plant cells typically have larger central vacuoles that occupy a significant portion of the cell volume. These large vacuoles in plant cells serve various functions including storage of water, ions, and other molecules, as well as maintaining turgor pressure. Animal cells, on the other hand, have smaller and more numerous vacuoles, and they do not have a central vacuole like plant cells. Therefore, option B is also correct.
Cell wall:
The cell wall is a rigid structure that surrounds the cell membrane in plant cells, bacteria, fungi, and some protists. It provides support and protection to the cell. Animal cells, however, do not have a cell wall. Instead, they have a flexible cell membrane that allows for greater movement and flexibility. Therefore, option C is also correct.
Conclusion:
In conclusion, animal cells do not possess plastids, large vacuoles, or a cell wall. These features are unique to plant cells and are not present in animal cells.

C) cell wall is not present in animals but they found only in plant cell .
