2. 1.WAT IS A CELL?? LIVING THINGS ARE MADE UP OF TINY UNITS CALLED CELLS.

3. CELLS ARE THE SMALLEST LIVING UNITS IN A LIVING THING,

4. SOME LIVING THINGS ARE MADE UP OF A SINGLE CELL. THEY ARE UNICELLULAR. OTHER LIVING THINGS ARE MADE UP OF MANY CELLS. THEY ARE MULTICELLULAR.

5. 2.WHAT ARE CELLS LIKE ?? CELLS DIFFER IN SHAPE AND SIZE.

6. 3.PARTS OF A CELL. CELLS HAVE 3 DIFFERENT PARTS. MEMBRANE: IS THE COVERING AROUND THE CELL. NUCLEUS: IS THE PART WHICH CONTROLS THE CELL. CYTOPLASM: IS BETWEEN THE NUCLEUS AND THE MEMBRANE.

7. PLANT CELLS ALSO HAVE A HARD CELL WALL AROUND THE MEMBRANE. THIS IS WHY SOME PLANT STEMS ARE HARD.

9. 1.HOW ARE LIVING THINGS ORGANISED??

10. MULTICELLULAR LIVING THINGS HAVE THE FOLLOWING STRUCTURE. CELLS FORM TISSUES: TISSUES, ARE MADE UP OF CELLS WHICH WORK TOGETHER.

11. TISSUES FORM ORGANS: ORGANS ARE MADE UP OF CELLS WHICH WORK TOGETHER. ORGANS FORM SYSTEMS: SYSTEMS ARE MADE UP OF ORGANS WHICH WORK TOGETHER.

12. AN ORGANISM IS A COMPLETE LIVING THING: SYSTEMS WORK TOGETHERIN A ORGANISM. ALL LIVING THINGS ARE ORGANISMS. ALL THE SYSTEMS WORK TOGHETHER TO KEEP A LIVING THING HEALTY.

13. SOME PICTURES: The tissue

14. MUSCLE CELLS.

15. INFORMATION: CELLS ARE THE FUNDAMENTAL UNITS MORPHOLOGICAL,PHYSIOLOGI CAL AND BREEDING OF ALL LIVING THINGS. THE CELLS ARE PROKARYOTES OR EUKARYOTES.

16. EUKARYOTES CELLS ARE CHARACTERIZED BY THEIR GENETIC MATERIAL ENCLUDED IN A SEPARATE NUCLEUS OF THE CYTOPLASM BY A MEMBRANE. PROCARYOTES ARE THE SIMPLEST.THEIR GENETIC MATERIAL IS IN THE DIREC CONTAC WITH THE CYTOPLASM.

17. THERE ARE 2 TYPES OF EUKARIOTIC CELLS:ANIMALS AND PLANTS. BOUTH HAVE IN COMUN THE GOLGI APPARATUS,THE NUCLEUS AND THE ENDOPLASMATIC RETICULUM AMONG OTHERS.
