Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects.

what does prokaryotic mean?
Bacteria are an example of prokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.
2 of 6
describe the features of bacterial, (prokaryotic) cells.
The genetic material (DNA) is localized to a region called the nucleoid which has no surrounding membrane. The cell contains large numbers of ribosomes that are used for protein synthesis.
3 of 6
decribe the functions of the structures in animal and plant (eukaryotic) cells.
Part Function Nucleus Contains genetic material, which controls the activities of the cell Cytoplasm Most chemical processes take place here, controlled by enzymes Cell membrane Controls the movement of substances into and out of the cell

what is a specialized cell?
Specialized cells perform specialized functions in multicellular organisms. Groups of specialized cells cooperate to form a tissue, such as a muscle. Different tissues are in turn grouped together to form larger functional units, called organs.
5 of 6
what is differentiation?
Different tissues have different kinds of cells. Differentiation occurs many times when a multicellular organism changes from a single zygote to a complex system of many tissues and cell types.
