CYTOPLASM

DEFINITION

➤CYTOPLASM IS THE SEMI-VISCOUS AND SEMI TRANSPARENT SUBSTANCE

    BETWEEN PLASMA MEMBRANE AND NUCLEAR MEMBRANE.

DIVISION OF LIVING CONTENT 

➤THE LIVING CONTENTS OF THE EUKARYOTIC CELL ARE DIVIDED INTO NUCLEUS 

AND THE CYTOPLASM THE TWO COLLECTIVELY FORM PROTOPLASM .

CONSIST OF;

➤CYTOPLASM CONSISTS OF AN AQUEOUS GROUND SUBSTANCE CONTAINING A

 VARIETY OF CELL ORGANELLES AND OTHER INCLUSIONS SUCH AS INSOLUBLE

 WASTES AND STORAGE PRODUCTS. 

CYTOSOL;

➤THE SOLUBLE PART OF THE CYTOPLASM IS CALLED CYTOSOL.

IT FORMS THE GROUND SUBSTANCE OF THE CYTOPLASM.

CHEMICALLY;

➤CHEMICALLY IT IS ABOUT 90% WATER.

TRUE SOLUTION;

➤IN THE CYTOSOL, SMALL MOLECULES AND IONS MAY FORM TRUE SOLUTION, 

COLLOIDAL SOLUTION;

➤AND SOME LARGE MOLECULES FORM COLLOIDAL SOLUTION. COLLOIDAL 

SOLUTION MAY BE  SOL (NON-VISCOUS) OR A GEL (VISCOUS). 

PERIPHERAL PART;

➤PERIPHERAL PARTS OF THE CELL ARE OFTEN  LIKE GEL.  

FUNCTION;

➤THE MOST IMPORTANT FUNCTION OF THE CYTOPLASM IS TO ACT AS A

 STOREHOUSE  OF VITAL CHEMICALS.

 IT IS ALSO A SITE FOR CERTAIN METABOLIC PROCESSES SUCH AS GLYCOLYSIS. 

IN LIVING CELLS;

➤IN LIVING CELLS THE CYTOPLASM CONTAINS SEVERAL CELL ORGANELLES

 SUCH AS;

 ✦ENDOPLASMIC RETICULUM,

  ✦MITOCHONDRIA,

 ✦GOLGI COMPLEX,

  ✦NUCLEUS, 

 ✦PLASTIDS,

  ✦RIBOSOMES,

  ✦LYSOSOMES AND CENTRIOLE. 

FREE FLOATING CELL ORGANELLE;

➤THE FREE FLOATING CELL ORGANELLES LIKE MITOCHONDRIA MOVE ABOUT

IN CYTOPLASM DUE TO CYTOPLASMIC STREAMING MOVEMENTS. THIS IS AN 

ACTIVE MASS MOVEMENT OF CYTOPLASM.
