2. RELATIVE SIZES OF THINGS

5. CHARACTERISTICS OF PROKARYOTIC CELLS no membrane bound organelles (e.g. nucleus) have a cell wall but different from plant cell wall e.g. bacteria AUTOTROPHS an organism able to make its own food chemoautotrophs HETEROTROPHS need to consume food for energy

6. EVOLUTION OF EUKARYOTIC CELLS FROM PROKARYOTIC CELLS autotroph became heterotroph once lost cell wall Membrane bound organelles formed Consumed mitochondria/chloro plast type prokaryotes Formed endosymbiotic relationships

7. Neutrophil migration across bone marrow

8. B cell Portion of pancreas cell

10. NUCLEUS nucleolus (pl. nucleoli) nucleoplasm chromatin nuclear membrane nuclear pore

12. Alzheimer's and the ER ER recognizes and targets excess proteins for degradation. If overloaded, a stress response is switched on. Prolonged stress leads to cell death and neuronal loss in Alzheimer's (who have excess protein in brain)

13. GOLGI APPARATUS functional and structural impairments have been found in Alzheimer’s patients

14. THE MAKING, MODIFYING, AND TRANSPORT OF PROTEINS Info to make proteins Ribosomes on RER make primary structure of proteins GA modifies proteins Vessicle transports proteins e.g. lysosome

15. LYSOSOMES AT WORK Tay Sachs disease has dysfunctional lysosomes leads to paralysis, dementia, blindness, and death Common in Quebeckers, jews

16. MITOCHONDRION

18. Tracking hominid migration through mitochondrial DNA

19. Mitochondria and Aging

20. CENTROSOME WITH CENTRIOLES

21. MICROVILLI

22. flagelli cillia

24. cell wall membrane chloroplast mitochondrion vacuole (tonoplast)

25. CHLOROPLAST

26. JUNCTIONS BETWEEN CELLS Tight junction Gap junction

27. Desmosomes

28. Cell membrane Cell wall cytoplasm ribosomes nucleus Golgi apparatus mitochondrion ER chloroplast centriole lysosome prokaryote animal plant

29. TYPES OF ANIMAL CELLS A. Epithelial cells

30. B. Blood or Vascular Cells

31. C. Nervous

32. D. Muscle

33. E. Connective and Supportive

34. PLANT CELL TYPES

35. MERISTEMATIC CELLS Cell division takes place here

36. PARENCHYMA CELLS Variety of functions in the plant

37. COLLENCHYMA alive SCLERENCHYMA dead

38. Homework Choose one type of cell and discuss how it is structured to perform is function. Identify any organelles that are particularly important for that type of cell.
