    Study Notes

    Overview of Cells

    • Cells are the fundamental unit of life, forming the basic building blocks of all living organisms.
    • Composed of tissues and organs, each specialized for specific functions.
    • Organisms can be unicellular (single-celled) or multicellular.

    Types of Organisms

    • Prokaryotes:

      • Simple, unicellular organisms without a defined nucleus or membrane-bound organelles (e.g., bacteria, archaebacteria).
      • Likely the first living organisms on Earth.
    • Eukaryotes:

      • More complex organisms with a defined nucleus and membrane-bound organelles.
      • Can be unicellular (e.g., protozoans) or multicellular (e.g., plants, animals, fungi).

    Key Cell Components

    • Nucleoplasm:

      • Fluid inside the nucleus that suspends chromosomes.
    • Nucleolus:

      • Specialized regions within chromosomes, containing multiple copies of genes.
    • Nucleus:

      • Contains the cell's genetic information; the most prominent organelle.
    • Lysosome:

      • Organelle responsible for breaking down foreign materials and waste within the cell.
    • Smooth Endoplasmic Reticulum (Smooth ER):

      • Involved in lipid synthesis and detoxification of harmful substances.
    • Golgi Complex:

      • Modifies, packages, and stores products from the rough endoplasmic reticulum.
    • Rough Endoplasmic Reticulum (Rough ER):

      • Site of most protein synthesis within the cell.
    • Ribosomes:

      • Cellular structures responsible for translating RNA into proteins.
    • Cytoplasm:

      • Jelly-like fluid holding all cell contents, providing a medium for cellular processes.
    • Plasma Membrane:

      • Selectively permeable membrane that encases the cell, controlling the movement of substances in and out.
    • Mitochondria:

      • Powerhouse of the cell, producing ATP (adenosine triphosphate), the energy currency of cells.

    Genetic Similarities

    • Both prokaryotes and eukaryotes share DNA and use the same genetic code, indicating a common ancestor.
