Osmosis is the movement of water by diffusion across a semi-permiable membrane. The student placed the cheek cells in water and when cells are placed in an environment of a high concentration of a particular substance, the cell practices osmosis where the water moves from a high concentration (the water on the slide), to a low concentration (the cheek cells) until they reach equilibrium. In this case, the process of osmosis did not cease as the cells were immersed in such a high concentration of water and it continued until the cell was so full that it burst.
Unlike plant cells, cheek cells do not have a cell wall and their membrane is semi permeable, thus allowing water to travel through. The cell reacts to this water in almost a form of 'shock' and it tries to make the inner contents of itself, equal to its surroundings.

When the onion cell is placed in the pure water the size of the cell would be bigger after one hour but when you placed the cheek cell into the pure water it will burst why is that so?
An Onion cell as a contractile vacuole. This allows the cells to remover more water especially when placed into a hypotonic solution. An epithelial skin cell of the cheek does not have a contractile vacuole. The acess water cannot be stored, therefore the cell bursts.
How is a cheek cell and elodea cell different?
The cheek cell does not have a large central vacoule, a cell wall and chloroplast, things which the Elodea cell has.
Is cheek cell a system?
It is a system!
Describe how the onion and cheek cell were different in observed parts what parts did they have in common?
The Onion cell and cheek cell both had cytoplasm, nucleuses, and cell membranes under 400x Magnification
Describe how the onion and cheek cell were similar in observed parts what parts did they have common?
Describe how the onion and cheek cell were similar in observed parts what parts did they have common? Well they are similar because they both have a nucleus and cytoplasm. They are different because in an onion cell there is a cell wall, doesnt have chlorplast, and it is a plant. For a cheek cell it has a cell membrane, doesnt have a cell wall, and is an animal.
Does the Nucleus have a cheek cell or leaf cell?
The cheek cell has a nucleus and so does a leaf cell.

Is a cheek cell an animal or a plant cell?
It is multicelluar because human is muticelluar animals probabaly cheek cell looked like nuicellular but the cheek cell is fall apart from our cheek.
Comparison between cheek cell to plant cell?
A cheek cell is a cell from a huma and a plant cell is a cell from a plant.
What is the word that means that a cell swells and burst?
When a cell swells and burst
Can a vein burst if you get cheek piercings?
no your vein cannot burst in your cheek it is mostly impossible dont worry Yes, you can have a ruptured vein if you have an inexperienced operator. Even if you let this close up, you will likely have a scar.
How is a cheek cell and elodea cell different?
The cheek cell does not have a large central vacoule, a cell wall and chloroplast, things which the Elodea cell has.
Is cheek cell a cell?
yes
Is cheek cell an animal cell why?
Yes, cheek cells are only present in animals. Plants do not have cheeks and hence do not have cheek cells :D
Definition of cheek cell?
cell membrane
How are plant cells different from cheek cells?
A cheek cell do not have cell wall and chloroplast while a plant cell have cell wall and some have chloroplast.
Do cheek cells have cell membranes?
yupp cheek cells are animal cells so they have cell membranes
