I believe it the cell membrane.
The thin structure that surrounds the cytoplasm of a cheek cell is called as cell membrane. This is present in most plant, animal and fungi cells. It is a selectively permeable structure and allows the flow of ions and particles from the inside of the cell to the outside and vice-versa. However plant cells, in addition to the cell membrane also have the cell wall outside the cell membrane. This provides mechanical rigidity to the cell and prevents the flow of larger particles.
cheek cells are very thin and u can tell because in the lab u have to stain the cheek cell to get a gud look at it and also because its like an animal cell and those are very thin too hope tat helps :)

In an onion slide preparation, thin layers of onion cells are placed on a slide, stained, and observed under a microscope to study cell structure. On the other hand, a cheek slide involves gently scraping cells from the inside of the cheek, staining them, and examining them microscopically. Both slides are commonly used in biology practicals to observe and compare plant (onion) and animal (cheek) cell structure.
The thin structure that surrounds a cell is known as the cell membrane, or plasma membrane. It acts as a protective barrier, controlling the passage of substances in and out of the cell, and plays a key role in maintaining the cell's internal environment.

The cheek epithelial cells are flat and irregularly shaped. They are polygonal squamous cells that have a very thin membrane.
Cheek cells are typically circular in shape because they are type of epithelial cell known as squamous epithelial cells. These cells are flat and thin, making them well-suited for covering surfaces like the inside of the cheeks and creating a barrier to protect the tissue underneath.

very thin, often a cell thick
The football-shaped structure consisting of thin fibers in a dividing cell is called the mitotic spindle. It is responsible for separating the chromosomes during cell division.
Spindle! :)
