What are 2 organelles that are not visible in the cheek cell?
List 3 organelles that were NOT visible but should have been in the cheek cell.
- Endoplasmic reticulum.
- Golgi body.
What 3 organelles were visible in the cheek cells?
Cheek Cells Under a Microscope Requirements, Preparation and Staining
- Cell membrane (outer boundary of the cell)
- Cytoplasm (the fluid within the cell)
- Nucleus (at the center of the cell and controls cell functions)
- Organelles (e.g. mitochondria-Organelles are cell structures with specific functions)
What organelles can be seen in cheek cells?
A prominent central nucleus is found in cheek cells. Cheek cells also have cellular organelles like mitochondria, Golgi apparatus, Endoplasmic reticulum, ribosomes, lysosomes, etc. They are transparent under a microscope and thus need to be dyed to view.
Which would you not be able to see in a human cheek cell?
Answer: The light microscope in the lab is not powerful enough to view other organelles in the cheek of the cell. The parts visible were the nucleus, cytoplasm, and the cell membrane.
Why is mitochondria not visible in cheek and onion cells?
The dye we used exposed the nucleus, so there is probably another dye that needs to be used to expose the mitochondria. Mitochondria (singular: mitochondrion) are visible with a light microscope but can’t be seen in detail.
What are 3 main differences between plant and animal cells?
Major structural differences between a plant and an animal cell include:
- Plant cells have a cell wall, but animals cells do not.
- Plant cells have chloroplasts, but animal cells do not.
- Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles, if any are present.
What is the natural color of cheek cells?
In class, we obtained cheek cells by scraping the inside of the mouth with a toothpick and then rubbing the toothpick on a drop of water with blue stain. The blue helps you see the cells which are normally a clear color.
How do cheek cells look like?
The cheek cell, an example of an animal cell, generally has a circular, oval shape. Due to the fact that the cheek cell was not in groups or clumps, the arrangement of this type of cell is unknown. Also, like the cheek cell, the onion skin cells were pushed together so that no spaces were in between.
Where are cheek cells found?
The tissue that lines the inside of the mouth is known as the basal mucosa and is composed of squamous epithelial cells. These structures, commonly thought of as cheek cells, divide approximately every 24 hours and are constantly shed from the body.
How do cheek cell look like?
It has a prominent nucleus and a flexible cell membrane which gives the cell its irregular, soft-looking shape. Like most eukaryotic cells, this cell is very large compared to prokaryotic cells. For scale, notice the pair of dark blue bacteria cells sticking to the right edge of the cheek cell.
What are the 4 main differences between plant and animal cells?
What kind of organelles would be visible in a cheek cell?
These are plant cells of a leaf of Elodea. the arrows are pointing at the nuclei. The green structures are chloroplasts. The small colorless dot-like structures are mitochondria. Note the box-like shape of these cells with straight boundaries indicative of having cell walls.
Are there any structures that can not be seen?
Any structures which cannot be seen. These include many small cytoplasmic organelles (e.g. ribosomes, cell membrane, lysosomes). For this reason the term “cell boundary” is used rather than the label “cell membrane” since the cell membrane is within the cell boundary but cannot be resolved.
How are human cheek cells different from other cells?
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.
Which is structure is seen in both cells?
Originally Answered: A human check cell and a spongy mesophyll cell are examined under a microscope. Which structure are seen in both cells? This is a human cheek cell stained with Janus Green. Note the nucleus and the numerous mitochondria. Also note the ovoid irregular shape of the cell reflecting an absence of a cell wall.
