Transcript

  • 1. CELLS! Structure, Function and Origin Wednesday, October 21, 2009
  • 2. Assessing prior knowledge: What is a CELL? Wednesday, October 21, 2009
  • 3. In this activity you will be viewing 12 different cells. Complete the following in your science notebook: 1. Sketch 1 cell from each of the 12 slides. 2. List any notable structural features of each cell (What does it look like?) 3. Infer about the function of each cell (What does it do?) Wednesday, October 21, 2009
  • 4. Wednesday, October 21, 2009
  • 5. Example: 1. Sketch 1 cell. 2. Structure - These cells are circular and “donut-shaped”. They do not appear to be connected and they look smooth on the surface. They are also red. 3. Function - These cells could possibly be carriers of hemoglobin within the bloodstream. Wednesday, October 21, 2009

  • 11. Halftime!!! Take a deep breath and stretch! Wednesday, October 21, 2009
  • 12. Wednesday, October 21, 2009
  • 13. Wednesday, October 21, 2009
  • 14. Wednesday, October 21, 2009

  • 16. Wednesday, October 21, 2009
  • 17. Wednesday, October 21, 2009
  • 18. The END!!! Take a moment to discuss each cell and how their structure is related to their function. Wednesday, October 21, 2009
  • 19. Origin Where do CELLS come from? Wednesday, October 21, 2009
  • 20. The “Cell Theory” tells us that “cells come from preexisting cells”. Wednesday, October 21, 2009
  • 21. CELLS will usually originate as a zygote or a stem cell (a cell that doesn’t have a job yet). Wednesday, October 21, 2009
  • 22. The zygote/stem cell will become specialized in structure and function through a process called differentiation. Wednesday, October 21, 2009
  • 23. This differentiation is the result of changes in gene expression not changes in the DNA code. Wednesday, October 21, 2009
