GOLGI BODY

👉Golgi body is also known as Dalton complex or Lipochondria.

👉 1st observed by "George".

👉 Morphological structure given by-           "Camilo Golgi".in nerve cell of Cat & born Owl. 

👉 Ultra structure given by "Dalton".

👉 In plant cell it is called Dyctoyosome. 

Number of Golgi body:-

✔ 1 in every animal cell.

✔ 6-12 in Plant cell. 

✔ In Lower Algae only one Golgi body are present in her body. 

✔ In Rhizoidal cells

        e.g. Chara(few hundred of GB are present)

NOTE(1) in vertebrae its position are peri-nuclear.

(2) In invertebrate & plant its position are Diffused/Scattered.

Structure of Golgi body:-

It has mainly 3 element.

       I) Cisternae

      II) Vaccuoles

     III) Vesicles                                                    GB are show polarity:-

 ✔ Concave(toward Plasma membrane)   it is also called trans form. 

 ✔ Convex (toward Nuclear membrane) 

 it is also called Cis form.

NOTE (1) Unicisternal Golgi body is a unique feature of Fungi.

Function of Golgi body:-

👉 Secretion & Packaging. 

   e.g. Polysaccharides➡ in goblet cell.

          Collagen➡Connective tissue. 

        Protein➡animal cells of Pancrease.

👉 Secretion of Hormone➡Thyroxine. 

👉 Vitellogenesis➡yolk formation. 

👉 Help in cell plate formation. 

👉 Secretion of middle lamella. 

👉 Glycosylation(addition of Carbohydrates to either Protein or Lipids molecules.                       (Lipid+Carbohydrates =Glycolipid)

 (Protein+Carbohydrates=Glycoprotein)

👉Acrosome of sperm formed by GB.

👉 Formation of Primary Lysosome. 

👉 Help in movement of macro molecular in cell.
