Are humans and onion plants unicellular or multicellular?
Are humans and onion plants unicellular or multicellular?
An onion plant and human are both “multicellular” organisms. If you take one cell out the onion or one cell out of the human, you’ve isolated some cells but they cannot live independently and freely without the rest of the onion plant or human body.
What type of cell is an onion cell?
plant cell
What cells can be unicellular or multicellular?
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. Unicellular organisms include bacteria, protists, and yeast.
Is an onion cell prokaryotic?
They are the prokaryotic cells. They do not have organelles bounded with membrane as they do not have a complex body. They even lack membrane around the nucleus. Onion cell is an example of plant eukaryotic cell and human cheek cell is an example of an animal eukaryotic cell.
What organelle is easiest to see inside an onion cell?
The easiest cellular structure to see is the cytoskeleton by proxy of the cytoplasm. The cytoplasm forms the largest portion of the cell, it can be easily identified as the space between all the other organelles, and it is universally present in all cells.
What is the main function of the cell inside your cheek?
These structures, commonly thought of as cheek cells, divide approximately every 24 hours and are constantly shed from the body. Cheek cells secrete a continuous supply of mucin, the principal element of mucous. In combination with the salivary glands, the mucin maintains a moist environment in the oral cavity.
Which chemical is used to stain human cheek cell?
Methylene blue
What cheek cells do not have?
Cheek cells are the epithelial cells (animal cells) and thus have a cell membrane, nucleus, mitochondria and Golgi apparatus but do not plastids.
Which part is not present in an animal cell?
Answer: The plant cell has a cell wall, chloroplasts, plastids, and a central vacuole—structures not found in animal cells.
