1. THE SMALLEST BIO UNIT ADAPTED TO PERFORM A PARTICULAR FUNCTION

2. PLANT

   • COVERED BY CELL WALL.
     • INNER WALL CELL MEMBRANE
       • CENTRE IS A LARGE VACUOLE
         • SURROUNDED BY TONOPLAST. FLUID IISIDE IS CELL SAP
         • FUNCTION : MAINTENANCE OF WATER BALANCE, PROVISION OF COLOUR BY PIGMENTS WITHIN IT
         • MITOCHONDRIA
           • OVAL OR ROD SHAPED
           • AEROBIC RESPIRATION TAKES PLACE TO RELEASE ENERGY
             • KNOWN AS POWER HOUSE FOR CELLS
           • GOLGI BODIES
             • MEMBRANE SACS STACKED ONE ON TOP OF EACH OTHER
               • KNOWN AS GOLGI COMPLEX
                 • FUNCTION : SECRETION OF SUBSTANCES, PACKAGING & SECRETION
             • RHIBOSOME
               • SMALL ORGANELLES WITHOUT A MEMBRANE
                 • FUNCTION : PROVIDING A PLACE FOR PROTEIN SYNTHESIS
                   • RIBOSOMES
               • ENDOPLASMIC RETICULUM
                 • MADE OF FLAT OR TUBULAR SACS WITHIN CYTOPLASM
                   • ROUGH ENDOPLASMIC RETICULUM
                     • TRANSPORT PROTEIN
                   • SMOOTH ENDOPLASMIC RETICULUM
                     • SYNTHESIS OF LIPIDS, STEROIDS & TRANSPORTTHEM WITHIN THE CELL
                 • CHLOROPLAST
       • MADE OF PHOSPHOLIPIDS & PROTEINS. SEMI PERMEABLE. FUNCTION IS TO ALLOW ENTRY IN & OUR OF THE CELL
     • DEAD STRUCTURE
     • MAINLT CELLULOSE
     • FUNCTIONS
       • MAINTAIN SHAPE
       • SUPPORT
       • PROTECTION

3. ANIMAL

   • NO CELL WALL
     • COVERED BY PLASMA / CELL MEMBRANE
       • CENTRE IS THE NUCLEUS
         • THE MAIN ORGANELLE IN A CELL
         • CONTAINS CHROMATIN BODY
           • DURING CELL DIVISION THE CHROMATIN CONVERTS INTO CHROMOSOMES
             • FUNCTION OF CHROMOSOM IS TO STORE GENETIC MATERIAL AND TRANSFER INHERITED CHARACTERS FROM GEN TO GEN
               • 46 CHROMOSOMES IN A HUMAN BODY
         • MITOCHONDRIA
           • GOLGI BODIES
             • CYTOPLASM IS JELLY LIKE
               • FUNCTION
                 • MAINTAIN SHAPE, BEAR CELL ORAGANELLES, CARRY OUT METABOLIC PREOCESSORS
