Cell walls are only found in plant cells, not animal cells: True or False?

This statement is true. Cell walls are a defining feature of plant cells and certain other organisms like fungi and bacteria. In plants, the cell wall provides structural support, protection, and helps maintain cell shape. It is primarily made of cellulose, a carbohydrate that forms a rigid structure. On the other hand, animal cells lack a cell wall; instead, they have a flexible cell membrane that allows for a variety of shapes and movement. Therefore, the absence of a cell wall in animal cells is what distinguishes them from plant cells.
