Chapter 5 Biology

1. COMPOUND LIGHT MICROSCOPE

1.1. Light microscope can resolve individual cells, it CANNOT resolve much of the internal anatomy,especially the organelles

2. DISSECTING MICROSCOPE

2.1. Allow user to see 3D structure –useful for surgery, dissection

2.2. OK for studying only the largest cellular structures (not organelles)

3. ELECTRON MICROSCOPE

3.1. Produces a detailed-image in static, 2-D, highly processed

4. EUKARYOTIC AND PROKARYOTIC CELLS

5. MICROSCOPE

6. CELL THEORY

6.1. All organisms are composed of one or more cells

6.2. Cells are the basic unit of structure & life for all organisms

6.3. Cells can arise only by division from a preexisting cell

7. DIFFERENCE

8. PROKARYOTIC

9. EUKARYOTIC

10. DESCRIPTION

11. NUCLEUS

12. DNA ARRANGEMENT

13. MEMBRANE BOUND ORGANELLES

14. UNICELLULAR/ MULTICELLULAR

15. Most primitive kind of cells and simplest organism

16. Evolved from prokaryotic cells more complex structural composition

17. no

18. yes

19. Circular (free floating)

20. Linear (inside nucleus)

21. Absent

22. present

23. All are unicellular

24. Mostly multicellular Some unicellular
