- 6. Nucleus • Brain ofthe Cell • Responsible for Critical Cellular operations • Stores genetic material
- 7. Nucleus • Brain ofthe Cell • Responsible for Critical Cellular operations • Stores genetic material Cell Membrane • Defines Boundary of Cell • Holds the structure of the Cell • Holds the Internals of the Cell at their respective positions
- 8. Golgi Complex • Sortsthe proteins synthesized by ER section • Synthesize Glycolipids • Secretes mucus
- 9. Cytoplasm • Fluid insideCell membrane • Allows the transfer of materials through and out of the cell • Also protects and holds the organelles Golgi Complex • Sorts the proteins synthesized by ER section • Synthesize Glycolipids • Secretes mucus
- 10. Endoplasmic Reticulum • Givesinternal support to the cytoplasm • RER synthesize secretory proteins and membrane proteins • SER synthesize lipids for cell membrane
- 11. Vacuoles • Store varioussubstances including waste products • Maintain osmotic pressure of the cell • Store food particles in amoeba cells Endoplasmic Reticulum • Gives internal support to the cytoplasm • RER synthesize secretory proteins and membrane proteins • SER synthesize lipids for cell membrane
- 12. Mitochondria • Synthesize energyrich compound ATP • ATP molecules provide energy for the vital activities of living cells
- 13. Mitochondria • Synthesize energyrich compound ATP • ATP molecules provide energy for the vital activities of living cells Lysosome • Help in digesting of large molecules • Protect cell by destroying foreign invaders like bacteria and viruses • Degradation of worn-out organelles • In dead cells perform autolysis
- 14. Cytoskeleton • Determine theshape of the cell • Give structural strength to the cell • Responsible for cellular movements
- 15. Neurons RBC WBCPlatelets
- 16. Some Interesting Factsabout Cell • In every 24 hours, a cell divides to produce new cell • First Cell appeared on earth was around 4 B year ago • Entire human species consist of more cells (2.8*1023) than total number of stars in observable universe (4*1022) • The largest cell on the earth is Ostrich Egg • Smallest cell in Human Body is Sperm while Largest is Egg • 70% of Cell is water while rest is starch, proteins and lipids • Longest cell in the human body are Motor Neurons (length about 4.5 ft) which runs from lower spinal cord to big toe
- 17. Some Interesting Factsabout Cell • RBC’s are created in Bone marrow and without them oxygen will need 3 years to get transferred from lungs to toes • At any given time, a typical cell carries out 200-500 biochemical reactions • Human brain alone contains almost 80 B cells • The human body has around 200 different sophisticated cells
