1. Chapter 7
A View of the Cell

2. Anton van Leeuwenhoek
Created the first microscope

3. Robert Hooke
First scientist to use the term cell in reference to living things
Used it incorrectly

4. Robert Brown
First to use the term nucleus to reference dark object in the center of a cell

5. Schleiden and Schwann
First scientists to state that all plants and all animals are made of cells

6. Rudolf Virchow
Stated that all cells come from pre-existing cells

7. The Cell Theory All organisms are made of one or more cells
Cells are the basic unit of structure and function in living things
All cells come from pre-existing cells

8. Compound light microscope
Uses multiple lenses to magnify object
Maximum magnification is 1500x

9. Electron microscopes Uses electrons to magnify objects
Maximum magnification is 500,000x
SEM and TEM

10. Two Basic Cells
Prokaryotes
Eukaryotes

11. Prokaryotes Do not have a nucleus
Do not have membrane-bound organelles
Ex} bacteria

12. Eukaryotes Do have nuclei Do have membrane-bound organelles
Ex} amoeba, yeast, plant and animal cells

13. Plasma Membrane Boundary between the cell and its environment
Gives cell its shape
Allows certain things to move in and out
Selective permeability

14. Cytoplasm Helps give cell shape Place where chemical reactions occur
Suspends cell parts

15. Cell Wall Rigid structure outside plasma membrane
Provides support and protection
Found in plants, fungi, protists, and bacteria

16. Nucleus
Controls cell activity
Contains chromosomes and DNA

17. Nucleolus
Found inside the nucleus
Makes ribosomes

18. Ribosome Located in the cytoplasm Makes proteins
One of the few organelles found in a prokaryotic cell

19. Endoplasmic Reticulum
Involved in chemical reactions
Transport system

20. Golgi Apparatus
Packages and sorts proteins to be shipped to other parts of the cell

21. Vacuole Storage site for water, minerals, food, and sometimes waste
Gives shape to plant cell
Usually not found in animal cells

22. Lysosome
Contain digestive enzymes to destroy worn-out cell parts and bacteria

23. Plastid
Storage site for starch and pigments
Found only in plants

24. Chloroplast Where photosynthesis takes place
Found only in plants and some protists

25. Mitochondria Place in cells where glucose is converted into energy
The “powerhouse”

26. Cytoskeleton Similar to human skeleton, except it can change its shape
Microtubules and microfilaments

27. Centrioles Play a role in cell division
Found only in animals and some protists

28. Cilia and Flagella
Used for locomotion
Not found on all cells
