What are cheek cells made of?
Skin is made of epithelial cells. Hence, cheek cells are made of epithelial cells.
Do cheek cells have chloroplasts?
Organelles like nucleus, mitochondria and vacuoles are common to both plant and animal cells. The cell membrane is also found in both these cells, but the cell wall is found only in plant cells. The chloroplast is also an organelle that is present only in plant cells. So, cheek cells will not have them.
Do cheek cells have vacuoles?
Unlike onion cells, human cheek cells have a dense cytoplasm. It is granular and occupies a large space within the cell. Also, human cheek cell has several, small vacuoles. A prominent nucleus is found at the center of the cell.
Do cheek cells have Golgi apparatus?
Cheek cells are the epithelial cells (animal cells) and thus have a cell membrane, nucleus, mitochondria and Golgi apparatus but do not plastids. Plastids are the organelle in plant cells. Thus, the correct answer is option D.
Do cheek cells have nucleus?
This human cheek cell is a good example of a typical animal cell. 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.
Why is mitochondria not visible in cheek and onion cells?
Answer. Mitochondrion were not visible because they are too small to be seen with our microscopes. Mitochondrion ARE PRESENT in both cell, but were not visible to us in the lab.
Do human cheek cells have ribosomes?
A prominent central nucleus is found in cheek cells. Cheek cells also have cellular organelles like mitochondria, Golgi apparatus, Endoplasmic reticulum, ribosomes, lysosomes, etc.
What is special about cheek cells?
Cheek cells are eukaryotic cells (cells that contain a nucleus and other organelles within enclosed in a membrane) that are easily shed from the mouth lining. It's therefore easy to obtain them for observation.
What cells are cheek cells?
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.
Can you see mitochondria in cheek cell?
1 Answer. No, they are too small to be seen without an electron microscope, which can magnify about 10,000,000x.
What organelles are readily seen under the light microscope?
Note: The nucleus, cytoplasm, cell membrane, chloroplasts and cell wall are organelles which can be seen under a light microscope.

What are the parts of a cheek cell?
It's therefore easy to obtain them for observation. Some of the main parts of a cell include: 1. Cell membrane (outer boundary of the cell) 2. Cytoplasm (the fluid within the cell)
How to get cheek cells?
Cheek cells can be easily obtained by gently scraping the inside of the mouth using a clean, sterile cotton swab. Once the cells have been obtained, the following procedure is used for cheek cell wet mount preparation: smear the cotton swab on to the center (part containing the saline drop) of the clean slide for about 4 seconds to get ...
What are the two structures that control the cell functions?
1. Cell membrane (outer boundary of the cell) 2. Cytoplasm (the fluid within the cell) 3. Nucleus (at the center of the cell and controls cell functions) 4. Organelles (e.g. mitochondria-Organelles are cell structures with specific functions)
How to get cells on a slide?
place a drop of physiological sa line on a clean microscopic slide (central part of the slide) smear the cotton swab on to the center (part containing the saline drop) of the clean slide for about 4 seconds to get the cells on to the center of the slide. add a drop of methylene blue solution on to the smear and gently place a cover slip on top ...
What color is the nucleus?
When a drop of methylene blue is introduced, the nucleus is stained, which makes it stand out and be clearly seen under the microscope. Although the entire cell appears light blue in color, the nucleus at the central part of the cell is much darker, which allows it to be identified.
Plasma Membrane
The plasma membrane is also termed as a Cell Membrane or Cytoplasmic Membrane. It is a selectively permeable membrane of the cell, which is composed of a lipid bilayer and proteins.
Cytoplasm
The cytoplasm is present both in plant and animal cells. They are jelly-like substances, found between the cell membrane and nucleus. They are mainly composed of water, organic and inorganic compounds. The cytoplasm is one of the essential components of the cell, where all the cell organelles are embedded.
Nucleus
The nucleus is a double-membraned organelle found in all eukaryotic cells. It is the largest organelle, which functions as the control centre of the cellular activities and is the storehouse of the cell’s DNA. By structure, the nucleus is dark, round, surrounded by a nuclear membrane.
Endoplasmic Reticulum
The Endoplasmic Reticulum is a network of membranous canals filled with fluid. They are the transport system of the cell, involved in transporting materials throughout the cell. There are two different types of Endoplasmic Reticulum:
Mitochondria
Mitochondria are called the powerhouses of the cell as they produce energy-rich molecules for the cell. The mitochondrial genome is inherited maternally in several organisms. It is a double membrane-bound, sausage-shaped organelle, found in almost all eukaryotic cells.
Plastids
Plastids are large, membrane-bound organelles which contain pigments. Based on the type of pigments, plastids are of three types:
Ribosomes
Ribosomes are nonmembrane-bound and important cytoplasmic organelles found in close association with the endoplasmic reticulum. Ribosomes are found in the form of tiny particles in a large number of cells and are mainly composed of 2/3rd of RNA and 1/3rd of protein.
