Answer: The correct answer is for the blank is -
human cheek cell.
Cell wall can be described as a rigid layer, composed of polysaccharides (such as cellulose in higher plants) and present outside the cell membrane ( also called plasma membrane) in plants, fungi, and bacteria.
It is absent in animal cells, such as human cheek cells (where only cell membrane is present, surrounding the cytoplasm of cell).
Thus, human cheek cell does not contain cell wall.
