4. Cell is structural and functional unit of life

5.  M.J. SCHLEIDEN & T. SCHWANN  BASIC UNIT OF LIFE --------CELL  ALL LIVING ORGANISMS ARE MADE UPOF CELLS.  ALL LIFE FUNCTIONS OCCUR WITHIN CELLS.  ALL CELLS ARISES FROM PRE-EXISTING CELLS

6. PROKARYOTIC CELL

8. PLANT CELLS

9.  AUTOTROPHIC  DO NOT SHOW LOCOMOTION  SHOWS CELL WALL AND PLASTIDS  VACUOLES ARE LARGE

11. ANIMAL CELL

15. CELL WALL

17.  PROTECTION AGAINST VARIATIONS IN TEMPERATURE,HIGH WIND SPEED, ATMOSPHERIC MOISTURE  CELL WALL PROVIDE EXTRA PROTECTION.

18. CELL MEMBRANE

20.  CELL MEMBRANE /PLASMA MEMBRANE.  MADE UP OF PROTEINS, FATS AND LIPIDS.  ALLOWS NUTRIENTS TO ENTER AND REMOVE CELLULAR WASTE.  PROTECTIVE IN FUNCTION.

21. UNICELLULAR

24. PLASTIDS

25.  CHLOROPLAST:  CONSISTS GREEN COLOURED PIGMENT CHLOROPHYLL.  SITE OF PHOTOSYNTHESIS.  STARCH PRODUCTION.

31. MITOCHONDRIA

32.  SMALL KIDNEY SHAPED ORGANELLES.  VARIOUS CHEMICAL PROCESSES.  ENERGY PRODUCTION.  “POWER HOUSE OF THE CELL ”  USE OXYGEN FOR GENERATING ENERGY.

35. RIBOSOMES

36.  ATTACHED TO ENDOPLASMIC RETICULUM.  SCATTERED IN CYTOPLASM.  ASSOCIATED WITH PROTEIN SYNTHESIS

39. VACUOLES

40.  SAC LIKE STRUCTURE SURROUDED BY MEMBRANE.  STORES FOOD, ENZYME AND WASTE FOR SHORT PERIOD OF TIME.

42. NUCLEUS

43.  FOUND IN ALL EUKARYOTIC CELLS.  RED BLOOD CELLS (EXCEPTIONAL)  CONTROLS ALL ACTIVITY OF CELL.  SPHERICAL IN SHAPE.

45.  NUCLEUS CONSISTS OF THREAD LIKE STRUCTURE – CHROMOSOMES.  CHROMOSOMES CARRY GENES RESPONSIBLE FOR TRAITS OR CHARACTERS.  46 CHROMOSOMES IN HUMAN CELL.

50. NUCLEOLUS

54. MUSCLE CELLS

59. EGG CELL

63. NEURON CELLS

65. ENDOPLASMIC RETICULUM

66.  NETWORK OF MEMBRANOUS TUBES.  HELPS IN TRANSPORTATION.  OFTEN FOUND ASSOCIATED WITH RIBOSOMES.

67. LYSOSOMES

68.  LYSOSOMES ARE KNOWN AS ‘ SUICIDAL BAGS’ HELP IN DIGESTION OF FOREIGN BODIES. WORN OUT CELL PARTS.

69. CENTRIOLES AND CENTROSOMES

70.  PRESENT ONLY IN ANIMAL CELLS.  IMPORTANT ROLE IN DIVISION OF CELL.
