Structure of golgi body, Biology

STRUCTURE

Golgi body consists of :-

(1) Cisternae

  • These are plate like unbranched structure with dilated ends.
  • One golgi body has 4-8 cisternae. Mono cisternal golgi body present in fungi.
  • Dense opaque material between cisternae is called Nodes.
  • Each cisternae has two faces -

(i) Convex surface of cister nae which is towards nucleus is called cis- face or forming face. It absorbs chemicals inform of vesicles.

(ii) Concave surface of cisternae which is towards P.M. is called Trans-face or maturing face. Golgi body secrets chemicals through this surface inform of vesicles.

(2) Tubules

  • Branched and anastomosing tubules associated with cisternae.
  • Tubules connect cisternae to each other.

(3) Vacuoles

Large spherical structure associated to tubules.

(4) Vesicles

  • Spherical structures arise by budding from tubules.
  • Vesiccles are filled with secretory materials.
  • Around the golgi body, ground substance is present in which cell organelles (ribosomes) are absent. It is called zone of exclusion.
  • About 60% proteins and 40% phospholipids occur in Goigi body.
  • Enzymes - Transferase, Adenosine diphosphatase, Thiamine phosphatase, Glucose-6phosphatase.
  • Thiamine phosphatase is the marker enzyme of golgi body.
