Prokaryotic & Eukaryotic Cells definitions
1/15
  • Prokaryotic cells

    Cells lacking a nucleus and membrane-bound organelles, typically unicellular and smaller in size.
  • Eukaryotic cells

    Cells with a nucleus and membrane-bound organelles, can be unicellular or multicellular, and are larger in size.
  • Nucleus

    Membrane-bound organelle in eukaryotic cells housing linear DNA.
  • Nucleoid

    Region in prokaryotic cells where circular DNA is located.
  • Ribosomes

    Cell structures responsible for protein synthesis, differing in size between cell types.
  • Binary fission

    Simple cell division process in prokaryotic cells.
  • Mitosis

    Complex cell division process in eukaryotic cells, involving cytokinesis.
  • Cytokinesis

    Process following mitosis, dividing the cytoplasm of eukaryotic cells.
  • Circular DNA

    DNA structure found in prokaryotic cells.
  • Linear DNA

    DNA structure found in eukaryotic cells.
  • Membrane-bound organelles

    Structures within eukaryotic cells, absent in prokaryotic cells.
  • 70S ribosomes

    Smaller ribosomes found in prokaryotic cells.
  • 80S ribosomes

    Larger ribosomes found in eukaryotic cells.
  • Cell membrane

    Structure surrounding all cells, maintaining the cell's environment.
  • Biomolecules

    Essential molecules like carbohydrates, proteins, nucleic acids, and lipids found in all cells.
