Cell Organelles: Golgi Bodies and Lysosomes

An Overview of Key Cellular Structures

Golgi Bodies

    Definition

    Golgi bodies, or the Golgi apparatus, are membrane-bound organelles in eukaryotic cells.

    Structure

    They consist of a series of flattened sacs called cisternae, stacked together in the cytoplasm.

    Function

    They modify, sort, and package proteins and lipids for transport to other parts of the cell.

    Importance

    Essential for processes like protein secretion and the formation of lysosomes.

    Lysosomes

      Definition

      Lysosomes are membrane-bound organelles containing hydrolytic enzymes for breaking down substances.

      Structure

      They are spherical vesicles formed from the Golgi apparatus, with an acidic internal environment.

      Function

      They digest waste materials, cellular debris, and foreign particles through enzymatic hydrolysis.

      Importance

      Crucial for cellular cleanup, recycling nutrients, and defending against pathogens.
