Presentation Transcript

  1. Cells and Tissues

  2. Mitochondria Cell Membrane Rough Endoplasmic Reticulum Golgi Apparatus Nuclear Membrane Nucleolus Centrosome/ Centriole Chromatin Lysosome Ribosomes (red dots) Peroxisome Cytoplasm Smooth Endoplasmic Reticulum

  3. Flagella Nucleus Chromatin Nuclear Envelope Ribosome Nucleolus Microtubule Cell Membrane Rough ER Centriole Mitochondria Smooth ER Microvilli Cilia Golgi Apparatus Microtubule Microtubule Lysosome

  4. Organelle Functions Knowing functions are not required on the lab, but are helpful when clues are given in the question

  5. Movements through the membrane: Diffusion Movement of molecules from a high concentration to a low concentration No energy required

  6. Movements through the membrane: Filtration As blood flows through the capillary, smaller molecules are filtered out through tiny openings and larger molecules stay inside

  7. Testing Solutions Glucose Sucrose Water Iodine Test (test for starch) Color change from orange to dark purple Benedict’s Test (test for glucose) Color change from blue to orange

  8. Type of cell: • Type of solution: • Water is diffusing: RBC Isotonic Into and out of RBC equally

  9. Type of cell: • Type of solution: • Water is diffusing: Crenated RBC Hypertonic out of RBC faster

  10. Type of cell: • Type of solution: • Water is diffusing: Lysed RBC Hypotonic Into RBC faster

  11. Mitosis • Phase: • What is occurring: Interphase Nuclear envelope is visible DNA replication Cell performs its normal job

  12. Mitosis • Phase: • What is occurring: Prophase Nuclear envelope is disappearing Chromosomes forming

  13. Mitosis • Phase: • What is occurring: Metaphase Chromosomes line up along the center of the cell

  14. Mitosis • Phase: • What is occurring: Anaphase _______ are separating

  15. Mitosis • Phase: • What is occurring: Telophase Cytokinesis Nuclear membrane reforms Cell membrane forms

  16. Tissues

  17. Simple Squamous Lungs, endothelium of capillaries Diffusion, osmosis • Location: • Body Function:

  18. Simple Cuboidal • Location: • Body Function: Kidney tubules, glands, ovaries Secretion, absorption

  19. Simple Columnar • Location: • Body Function: GI tract, uterus Secretion, absorption, move sperm

  20. Pseudostratified Columnar • Location: Trachea • Function: Movement of fluids (mucous)

  21. Stratified Squamous • Location: • Body Function: Skin, mouth, anal canal, esophagus Protection water loss, abrasion etc….

  22. Transitional bladder Stretch • Location: • Body Function:

  23. Connective Tissues

  24. Loose Connective Tissue(Areolar) Collagen Fibers Elastic Fibers Reticular Fibers Fibroblasts

  25. Fat (adipose) Adipocyte Nucleus

  26. Reticular Reticular Fibers

  27. Dense Regular Nuclei of Fibroblasts Collagen Fibers

  28. Hyaline cartilage Chondrocytes Matrix Lacuna (space occupied by cell)

  29. Elastic Cartilage

  30. Fibrocartilage Chondrocytes Collagen Fibers

  31. Bone Osteocytes Central Canal

  32. Blood WBC RBC Platelets

  33. Skeletal Muscle • Location: • Body Function: Attached to Skeleton Voluntary movement

  34. Cardiac Muscle • Location: • Body Function: Intercalated Discs Heart Heart muscle contraction

  35. Smooth Muscle Blood vessels, GI tract Involuntary movement • Location: • Body Function:

  36. Nervous tissue CNS, PNS Conduct nerve impulses • Location: • Body Function:
