Detailed explanation-1: -Cheek cells are the epithelial cells (animal cells) and thus have a cell membrane, nucleus, mitochondria and Golgi apparatus but do not plastids.
Detailed explanation-2: -Thus, cheek cell doesn’t have cell wall. Q. Which organelle is not found in the human cheek cell and why?
Detailed explanation-3: -Because plastid is an organelle of plant cells, cheek cells do not contain it.
Detailed explanation-4: -The cell membrane of the cheek cell is semi permeable and it surrounds the cytoplasm. As it is an eukaryotic cell it contains Mitochondria, membrane bound cell organelles, nucleus, Golgi apparatus, etc. These structures or cell organelles are easily observed in human cheek cells.
