1. Basic Structure of a Cell

2. History of Cells & the Cell Theory Virchow Cell Specialization

10. Discoveries Since the Cell Theory

16. Which Cell Type is Larger? _________ > _____________ > ___________ Plant cell Animal cell bacteria

17. How Big is a Micron ( µ ) ? 1 cm = 10,000 microns 1” = 25,000 microns

21. Specialized Plant cells Xylem cells Pollen Guard Cells

22. Organization Levels of Life Atoms to Organisms

23. ATOMS  MOLECULES  ORGANELLES Nonliving Levels

24. CELLS – life starts here TISSUES – Similar cells working together Living Levels  

25. ORGANS ORGAN SYSTEMS ORGANISM Different tissues working together Different organs working together   More Living Levels

26. Simple or Complex Cells

31. Two Main Types of Eukaryotic Cells Plant Cell Animal Cell

32. Organelles

34. Animal Cell Organelles Nucleolus Nucleus Nuclear envelope Ribosome (attached) Ribosome (free) Cell Membrane Rough endoplasmic reticulum Golgi apparatus Mitochondrion Smooth endoplasmic reticulum Centrioles

35. Plant Cell Organelles

49. Inside the Nucleus - The genetic material (DNA) is found DNA is spread out And appears as CHROMATIN in non-dividing cells DNA is condensed & wrapped around proteins forming as CHROMOSOMES in dividing cells

53. Cytoskeleton MICROTUBULES MICROFILAMENTS

60. What do mitochondria do? Burns glucose to release energy (ATP) Stores energy as ATP “ Power plant” of the cell

66. Endomembrane System Includes nuclear membrane connected to ER connected to cell membrane (transport)

71. Golgi Animation Copyright Pearson Publishers

72. Golgi Animation Materials are transported from Rough ER to Golgi to the cell membrane by VESICLES

77. Cell Movement with Cilia & Flagella

78. Cilia Moving Away Dust Particles from the Lungs
