Physio day14- intro to cells

  1. 1. Abrew- Physiology<br />TODAY’S AGENDA:<br /><ul><li>Inquiry Chart (20)
  2. 2. Group activity-(CCD Chart)- Ch. 3.1-3.2 (20)
  3. 3. Notes- Overview of Cells (30)
  4. 4. Exit Quiz (5)</li></ul>29AugustM<br /><ul><li>Read p. 65-67
  5. 5. Reading Quiz Tuesday
  6. 6. Ch. 1 Test Remediation's- Due Friday </li></ul>ESLRs Addressed:<br />1. + Citizenship<br />2. + relationships <br />3. Problem Solvers<br />4. Effective communicators<br />Today’ objectives:<br />Name the 4 elements that make up the bulk of living matter.<br />List several trace elements.<br />Define a generalized cell.<br />
  7. 7. Review- Cell Discovery<br />Robert Hooke (1600’s)<br />Cork Plant tissue<br />Cube-like structures, reminder of “cells” at a monastery<br />Cells- smallest unit (or building block) of all living things<br />Human body- trillions of cells<br />
  8. 8. Robert Hooke<br />
  9. 9. Overview of the Cellular Basis of Cells (Ch. 3.1)<br />Chemical makeup of cells;<br />Primarily made up of4 elements<br />Carbon<br />Oxygen<br />Hydrogen<br />Nitrogen<br />
  10. 10. Overview of the Cellular Basis of Cells<br />Remaining part of cell is made up of several trace elements…<br />Calcium<br />Iron<br />Iodine<br />Sodium<br />Potassium<br />
  11. 11. Trace Elements and their cellular functions<br />Calcium- needed for blood clotting<br />Iron- makes hemoglobin which carries oxygen in the blood<br />Iodine- required to make a thyroid hormone that controls metabolism<br />Metals (Ca, Na, and K) can carry an electric charge when in their ionic form= electrolytes<br />Na and K essential for transmission of nerve impulses in muscle contraction<br />
  12. 12. Cell Facts<br />Water- makes up about 60% of a cell!!!<br />Cells are constantly bathed in interstitial fluid (dilute saltwater solution), derived from the blood.<br />All chemical exchanges (between blood and cell) are made through the interstitial fluid.<br />
  13. 13. Vary in length…<br />2 micrometers- over 3 feet (nerve cells)<br />Structure reflects function<br />Cell Facts<br />
  14. 14. Anatomy of the Generalized Cell (Ch. 3.2)<br />Generalized Cell- typical features of all cells.<br />3 Main features of most cells:<br />Nucleus- (control-center, “headquarters”, contains genetic material)<br />Plasma membrane- (fragile barrier that contains the cells contents and separates the them from the surrounding environment)<br />Cytoplasm- (the material outside the nucleus and inside the plasma membrane)<br />
  15. 15. Generalized Cell<br />
  16. 16. Exit Quiz<br />What are the 4 primary elements that make up a cell?. (4pts)<br />What is the name of the fluid that cells are bathed in? (1pt)<br />List at least 4 trace elements? (4pts)<br />What are the 3 main features of a cell? (3 pts)<br />
