Prokaryotic cells, found in bacteria and archaea, lack a nucleus and other membrane-bound organelles. Eukaryotic cells, found in plants and animals, have a nucleus and more complex organelle structures.
Cells are the basic structural and functional units of living organisms. They consist of three main parts: the plasma membrane, cytoplasm, and nucleus. The plasma membrane acts as a barrier, regulating what enters and leaves the cell. Cytoplasm is the jelly-like substance inside the cell, containing organelles and essential molecules. The nucleus houses the cell's genetic material, controlling cellular functions and growth.
Cells are composed of several essential organelles, including:
