The nucleus is present at the centre of the cytoplasm.The absence of a cell wall and a prominent vacuole are indicators that help identify animal cells, such as cells seen in the human cheek. The vacuole in an an animal cell is smaller in size, or absent. Unlike plant cells, the cytoplasm in an animal cell is denser, granular and occupies a larger space. Human Cheek CellĪs in all animal cells, the cells of the human cheek do not possess a cell wall. A cell membrane that is semi-permeable surrounds the cytoplasm. The presence of a cell wall and a large vacuole are indicators that help identify plant cells, such as seen in the onion peel. The vacuole is prominent and present at the centre of the cell. The nucleus is present at the periphery of the cytoplasm. As in all plant cells, the cell of an onion peel consists of a cell wall, cell membrane, cytoplasm, nucleus and a large vacuole. Onion CellĪn onion is a multicellular (consisting of many cells) plant organism. The Theoryīefore exploring the details of cell structure, let's understand the differences in the structure of an onion cell and a human cheek cell.
