ANATOMY - CELL , ORGANELLES

1. TOPIC-

2. INTRODUCTION-
IT IS BASIC FUNDAMENTAL
UNIT OF THE BODY /
PHYSICAL BASIC OF LIFE /
BASIC UNIT OF LIFE
FATHER OF CELL – ROBERT
HOOKE

3. CONT…
 A CELL CONSISTS OF PLASMA MEMBRANE
INSIDE WHICH THERE ARE A NUMBER OF
ORGANELLES .
 ORGANELLES ARE SMALL STRUCTURE WHICH
HIGHLY SPECIALIZED FUNCTION.
 THE INCLUDE NUCLEUS , MITOCHONDRIA ,
RIBOSOME , LYSOSOME , ENDOPLASMIC
RETICULUM , GOLGI APPARATUS ETC.

4. PLASMA MEMBRANE / CELL
MEMBRANE-
COMPOSED OF DOUBLE LAYER
OF PHOSPHOLIPIDS AND
PROTEINS -
– SURROUNDS OUTSIDE OF ALL CELLS
– CONTROLS WHAT ENTERS OR
LEAVES THE CELL
– LIVING LAYER

5. PHOSPHOLIPIDS -
HEADS WHICH IS ELECTRICALLY
CHARGED AND HYDROPHILLIC
(WATER LOVING).
TAILS WHICH HAS NO CHARGED
AND HYDROPHOBIC (WATER
HATING)

6. CELL ORGANELLES-
 A CELL CONSISTS OF PLASMA MEMBRANE
INSIDE WHICH THERE ARE A NUMBER OF
ORGANELLES .
 ORGANELLES ARE SMALL
STRUCTURE WHICH HIGHLY
SPECIALIZED FUNCTION.
 THEY INCLUDE NUCLEUS , MITOCHONDIA,
LYSOSOMES, ENDOPLASMIC RETICULUM,
GOLGI APPARATUS ,

7. 1- NUCLEUS-
LARGEST CELL ORGSNELLES.
 ROUND OR EGG SHAPED .
CONTROLLER OF CELL .
 ABSENT IN RBC

8. 2-MITOCHONDRIA -
 SURROUNDED BY A DOUBLE MEMBRANE .
 IT IS THE POWER HOUSE OF CELL .
 ATP SYNTHESIS SITE.
 2ND LARGEST ORGANELLES .
 SEMI AUTONOMUS.
 1ST STEP OF HEME SYNTHESIS .
 HELP IN VITELLOGENESIS (YOLK
SYNTHESIS).
 SITE OF FATTY ACID SYNTHESIS.

9. 3-LYSOSOMES-
IT IS ALSO CALLED SUICIDAL BAG
OF CELL .
SCAVENGER OF CELL.
 DISPOSAL UNIT OF CELL

10. 4-RIBOSOME-
ENGINE OF CELL
 PROTEIN FACTORY OF CELL
SMALLEST CELL ORGANELLES
HIGHEST IN NUMBER

11. 5- ENDOPLASMIC RETICULUM-
A- ROUGH ENDOPLASMIC
RETICULUM –
-TRANSLATION AND FOLDING OF
NEW PROTEINS .
-SYNTHESIS OF PROTEIN .

12. CONT..
B- SMOOTH ENDOPLASMIC
RETICULUM-
-EXPRESSION OF LIPIDS
- DETOXIFICATION HARMFUL
CHEMICAL AND STORE CALCIUM.
-SYNTHESIS OF CHOLESTROL

13. 6- GOLGI APPRATUS-
IT IS ALSO CALLED POST OFFICE.
SORTING , PACKAGING ,
PROCESSING AND MODIFICATION
OF PROTEIN.
