true or false

1 animals cells have cell walls?

2 water and oxygen cannot pass through the cell wall?

1) TRUE
2) FALSE

2 true

1) FALSE. Animal cells do not have cell walls. Cell walls are a rigid structure found in plant cells, bacteria, and some algae, but not in animal cells.

2) TRUE. Water and oxygen cannot pass through the cell wall. The cell wall is primarily composed of cellulose, a complex carbohydrate that forms a barrier around the cell. This barrier prevents the free movement of most substances, including water and oxygen. Instead, animal cells rely on their cell membranes to control the movement of these molecules in and out of the cell.
