A is the answer. It’s like addition.
A cell wall is a permeable layer found in plant cells which acts as a membrane through which water molecules can pass through while animal cells do not have cell walls.. they just have a cell membrane which is selectively permeable to some chemicals or substances.. water does not move from the region of higher to lower concentration in animal cells
In short, plant cells have cell walls that allow osmosis while animal cells do not have cell walls for osmosis to take place
hope it helps you :)
