Final answer:
The characteristic of an animal cell that is NOT present is the cell wall.
Step-by-step explanation:
The correct answer is Cell Wall. A characteristic of an animal cell is that it lacks a cell wall, unlike plant cells. Animal cells have a plasma membrane that surrounds the cell and provides structure and protection. Plant cells, on the other hand, have a cell wall made of cellulose which provides additional support and protection.
Animal cells also do not contain chloroplasts, which are responsible for photosynthesis in plant cells. Chloroplasts are found in the cells of plants and some other organisms that can perform photosynthesis.
Lastly, while animal cells can have various shapes, they are typically not rectangular. They can have irregular shapes and sizes depending on their function and location within the organism.
