Which statement correctly describes the difference between cell membranes and cell walls?
Group of answer choices
The cell membranes of plant and animal cells are impermeable which allows nothing to pass, while the cell walls of plant cells are permeable which allows small things to pass.
Cell membranes are the outermost covering in plant cells, while cell walls are in direct contact with the cytoplasm of animal cells.
Cell membranes are only found in animal cells, while cell walls are found in both plant and animal cells.
The cell membranes of plant and animal cells are flexible and do not have a definite shape, while the cell walls of plant cells are rigid which gives plant cells a definite shape.
