All organisms are made of cells. An onion is and organism, hence all parts of an onion are made of cells.
By definition, a prokaryote is a single celled organism. An onion is made up of many cells, hence, it is a eukaryote.
Onion roots are not photosynthetic.They do not have.
The root cell's job is to gather minerals and and take it up the roots to the onion.
Onion cells are larger. Skin cheek cells are smaller probably due to the fact that they're overlapped or rolled up.
No chloroplasts in cheek and onion cells
Between the 2 cells that are cheek and onion cells, the one that has a regular arrangement and structure are onion cells. Cheek cells have an irregular shape.
Onion cells do not have chloroplasts because the onion is underground where there is no light. Without light chloroplasts have no purpose, so onion cells just don't have them.
more than one cell cause of the many layers.
They are living things
All cells have cytoplasm, so yes, onion cells have cytoplasm.
