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.
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.
A cheek cell is a eukaryotic animal cell that contains a nucleus and organelles, whereas an elodea cell is a eukaryotic plant cell with a cell wall and chloroplasts for photosynthesis. Additionally, elodea cells may have a large central vacuole for support and storage.
The Onion cell and cheek cell both had cytoplasm, nucleuses, and cell membranes under 400x Magnification
When animal cells burst it's called lysis.
Cytoplasm nucleus and cell membrane containing 46 chromosomes
It is multicelluar because human is muticelluar animals probabaly cheek cell looked like nuicellular but the cheek cell is fall apart from our cheek.
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.
When a cell swells and burst
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.
yes
Cheek cells are eukaryotic cells found in animals, whereas plant cells are eukaryotic cells found in plants. Cheek cells do not have a cell wall but have cell membranes, while plant cells have cell walls made of cellulose in addition to cell membranes. Cheek cells do not contain chloroplasts for photosynthesis, while plant cells do contain chloroplasts.
No, a sperm cell and a cheek cell do not have the same chromosomes. A sperm cell is a haploid cell containing 23 chromosomes, while a cheek cell is a somatic cell with 46 chromosomes, which is diploid.
The cheek cell has a nucleus and so does a leaf cell.
cell membrane
A cheek cell do not have cell wall and chloroplast while a plant cell have cell wall and some have chloroplast.
yupp cheek cells are animal cells so they have cell membranes
Yes, a cheek cell is an animal cell. Cheek cells are part of the epithelial tissue that lines the inside of the mouth, and they share many characteristics with other animal cells, such as having a nucleus, cytoplasm, and cell membrane.
