Dictyosome - English Definition & Meaning

Definition

A dictyosome is a stack of cisternae in the Golgi apparatus of plant cells and some invertebrates. Think of it as a single 'pancake' stack in a larger cellular kitchen 🥞. Plant cells often have many scattered dictyosomes rather than a single, centralized Golgi. Each dictyosome functions similarly to a Golgi body, processing and packaging proteins. These structures are critical for plant cell function. They support the plant's unique cellular needs. The term is sometimes used interchangeably with Golgi body, but technically refers to a single stack.

Etymology

The term "dictyosome" comes from the Greek "dictyon," meaning net or mesh, and "soma," meaning body. It describes the net-like appearance of the stacked cisternae. The term is mainly used in plant cell biology. It highlights the compartmentalized nature of the Golgi in plants. It helps differentiate the structure in plant vs. animal cells.
