dictyosome

A scientist observes a dictyosome through an electron microscope.

Definition
  1. Noun:
    • A netlike structure in the cytoplasm of animal cells: A dictyosome is a specialized organelle, part of the Golgi apparatus, characterized by its stacked, membrane-bound cisternae that form a network-like appearance. It is particularly prominent in cells that are active in secretion.
Usage Examples
  • Noun:
    • The dictyosome is involved in modifying, sorting, and packaging proteins for secretion.
    • Under the electron microscope, the dictyosome appears as a stack of flattened sacs.
Advanced Usage
  • "Dictyosome stack": Refers to the specific pile of membrane-bound cisternae that constitute a single .
    • Each dictyosome stack functions independently in processing cellular products.
Variants and Related Words
  • Golgi apparatus / Golgi complex (n): The larger cellular structure composed of multiple interconnected and associated vesicles.
    • The Golgi apparatus is often described as a collection of dictyosomes.
  • Golgi body (n): A historical and sometimes interchangeable term for the Golgi apparatus or an individual .
Synonyms
  • Golgi stack: A direct synonym emphasizing the stacked structure.
  • Golgi cisterna (plural: cisternae): Refers to the individual flattened membrane sacs that make up a .
Notes on Meaning
  • The term is used primarily in cell biology and histology. It is more specific than "Golgi apparatus," as it refers to one discrete stack within the larger Golgi complex. The word is derived from Greek (net) and (body).
