Presentation Transcript

  1. CELL

  2. DEFINITION • Is the basic form of life • The structural, functional and biological unit of all organisms • From Latin, cella(small chamber)

  3. HISTORY • ROBERT HOOKE- “Cork have cell” • ANTON VAN LEEUWENHOEK-observe bacteria and protozoa • ROBERT BROWN- Discover the plant’s nucleus • MATTHIAS SCHLEIDEN- plants have cell • THEODORE SCHWANN-animal have cell

  4. PARTS OF THE CELL • CELL MEMBRANE(Body guard of the cell) • CYTOPLASM(Living part of the cell) • NUCLEUS(command center)

  5. CELL MEMBRANE • --the fluid mosaic model (S.J Singer) -- semi-permeable--fluid portion is a double layer of phospholipids, called the phospholipids bi-layer

  6. JOB OF THE CELL MEMBRANE • Isolate the cytoplasm from the external environment • Regulate the exchange of substances • Communicate with other cells • Identification

  7. CYTOPLASM • Endoplasmic reticulum(smooth and rough) • Ribosomes • Vacuole(plant) and Vesicle(animal) • Golgi apparatus(golgi bodies) • Mitochondria(power house) • Chloroplast(plants only)

  8. CYTOPLASM • cytoskeleton • lysosome • Centrioles • Cell wall

  9. NUCLEUS • Nuclear membrane • Chromosomes • Nucleolus • Nuclear pore • chromatin

  10. THE END
