1. What do these have in common?

2. Cells! All living organisms have cells
Cells are the smallest unit of life

3. Cells Characteristics of living things: Making energy Respiration
Reproduction
Making proteins
Getting rid of waste

4. Parts or organelles Animal cells Plant cells Cell/plasma membrane
Cytoplasm
Nucleus
Mitochondria
Vacuole
Endoplasmic reticulum
Golgi apparatus
Plant cells
Cell/plasma membrane
Cytoplasm
Nucleus
Cell wall
Mitochondria
Vacuole
Endoplasmic reticulum
Golgi apparatus
Chloroplasts

5. Plasma membrane Surrounds and protects cell
Allows entry and exit of substances

6. Cytoplasm Takes up most of the cell Gel-like Transportation
Holds organelles in place

7. Nucleus
Contains chromosomes and genes
Growth and reproduction

8. Vacuole Storage of nutrients Storage of waste Water storage
Larger in the plant
cell

9. Endoplasmic Reticulum
Folded membrane that forms a series of canals
Protein production

10. Golgi Apparatus Cellular transport
Folded membrane that forms a series of canals
Cellular transport

11. Mitochondria
Absorbs nutrients to produce energy
Cellular respiration

12. Lysosomes
break down waste materials
The “stomach” of the cell

13. Cell Wall ONLY IN PLANTS Made of cellulose Surrounds cell membrane
Cell support and structure
Gives cell rigid shape

14. Chloroplast
ONLY in plants
For Photosynthesis
Contains chlorophyll

15. Microscopes
Many of the details of the cells have only been discovered since the discovery of the microscope
Antoni van Leeuwenhoek (1632— 1723)
Robert Hooke (1635—1703)
Marcello Malpighi (1628—1694)

16. Microscope

17. Eyepiece
Part you look through
Magnifies image 10x

18. Body
Eye piece and objective lens

19. Revolving Nosepiece Holds the objective lenses
Rotates so you can have different views of specimen

20. Objective Lenses Magnifies specimen
Magnifying lens must be multiplied by eyepiece to get total magnification
Ex. 10x (eye piece) X 4x (objective lens) = 40x magnification

21. Stage
Holds the slide
Allows light to pass through slide

22. Stage Clips
Hold slide in place

23. Condenser
Directs light towards specimen

24. Light Source
Illuminates specimen

25. Pointer
Points to specimen
Line you see when you look eyepiece

26. Arm
Connects base to body

27. Coarse-Focus Knob
Brings image into focus

28. Fine-Focus Knob Brings the image into fine focus
Used after the coarse-focus knob

29. Base
The base supports the microscope
