All cells contain dozens of different organelles. Some organelles are universal, and found in all types of cells. This includes the membrane, cryoskeleton, cytoplasm, and ribosomes. Various other organelles are shared or absent depending on the type of cell and the organelle. For example, the cell wall can be found in plant cells and bacteria cells, but not in animal cells.
Eukaryotic cells include the cells of animals, plants, protists, and fungi. The main difference in the organelle variation is that eukaryotic cells have a nucleus. All of the organelles of eukaryotic cells are membrane bound organelles. this means that all of their organelles have their own membrane surrounding them. This regulates what nutrients and molecules move in and out of the organelle.
Prokaryotic Cells are found in bacterial organisms and are commonly a solitary cell in the organism. These typess of cells do not contain a nucleus. Instead they contain a plasmid. A plasmid is an archive for the genetic information of the cell. Outside the cell there are pili. These finger like appendages allow the cell to stick to surfaces. In times of dormancy, the cell will grow a shell around itself to protect from the environment. It is comparable in function to a butterfly's cacoon.
