What is the conclusion in observing nucleus in cheek cell?
Answers
As 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. Unlike plant cells, the cytoplasm in an animal cell is denser, granular and occupies a larger space. The vacuole in an an animal cell is smaller in size, or absent. 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.

Please mark as brainliest.......
On observing the cheek cell under a microscope, following are the results:
- There are large irregularly shaped cells with separate cell walls.
- A separate nucleus at the center of each cell.
- A light colored cytoplasm in every cell.
Explanation:
To observe a cheek cell, a person will require a microscope, a glass slide, methylene blue solution, dropper, glycerine, and a cover slip. A cell has four main parts, a cell membrane which is the outer body of a cell, a fluid inside the cell known as cytoplasm and a nucleus which controls the functions of a cell.
