Understanding Cell Theory and Types: Prokaryotic vs Eukaryotic Cells

This overview of cell theory explains that all living organisms are composed of one or more cells, which serve as the basic unit of life. It emphasizes that new cells arise from preexisting ones and contain hereditary information (DNA). The two main types of cells—prokaryotes and eukaryotes—are described. Prokaryotes are unicellular without a nucleus, while eukaryotes are multicellular and have membrane-bound organelles. Examples of each type are provided, highlighting diverse organisms within the five kingdoms of life.

  1. Section 2: Types of Cells

  2. Cell Theory (Review) • All organisms (living things) are composed of one or more cells. • The cell is the basic unit of (life) structure and organization of organisms. • All (new) cells come from preexisting cells. • Cell contain hereditary information (DNA) which is passed from cell to cell during cell division

  3. Two Types of Cells • Cells can be subdivided into the following subcategories: • Prokaryotes: Unicellular • Eukaryotes: Multicellular

  4. Prokaryotic • Prokaryotes lack a nucleus and other membrane-bound organelles (contain ribosomes). • Few internal structures. • Bacteria are one-celled prokaryotes.

  5. Eukaryotic • Contain a nucleus and organelles surrounded by membranes (mitochondria, chloroplasts, lysosomes, vacuoles, etc.) Animal Plant
