WebIt is understood that there are two basic kinds of cells: prokaryotic cells and eukaryotic cells. Prokaryotes, such as bacteria and archaea, are simple cells that have no cell nucleus. … Eukaryotic Cell nucleus: A cell's information center, the cell nucleus is the most conspicuous organelle found in a eukaryotic cell. Mitochondria and chloroplasts: generate energy for the cell. Mitochondria are self-replicating double membrane-bound... See more The cell is the basic structural and functional unit of life forms. Every cell consists of a cytoplasm enclosed within a membrane, and contains many biomolecules such as proteins, DNA and RNA, … See more Cell shape, also called cell morphology, has been hypothesized to form from the arrangement and movement of the cytoskeleton. Many advancements in the study of cell morphology come from studying simple bacteria such as Staphylococcus aureus See more Many cells also have structures which exist wholly or partially outside the cell membrane. These structures are notable because they are not protected from the external … See more Cell specialization/differentiation Multicellular organisms are organisms that consist of more than one cell, in contrast to single-celled organisms.
