1. HOW WELL DO YOU KNOW THE CELL?

2. NUCLEUS Contains DNA – genetic material of the cell
2 membranes surrounding it, the envelope/membrane
Controls all of the cell’s activities – including information needed to make proteins

3. CYTOSKELETON Network of thin tubes in the cytosol
Maintain a cell’s shape, & act as tracks that guide organelles and molecules as they move through the cell

4. PLASMA (CELL) MEMBRANE
Covers cell surface
Determines what enters or exits the cell – selectively permeable

5. PROKARYOTE Cell that lacks a nucleus and membrane bound organelles
Bacteria and Archea

6. HOOKE
First person to identify and name cells – coined the term “cell”

7. ROUGH ENDOPLASMIC RETICULUM (ER)
Transports materials within the cell
has ribosomes attached
produces phospholipids and proteins

8. GOLGI APPARATUS Stacks of flattened, membranous sacs
Many proteins and lipids pass from ER to here for final modifications;
Like a POST OFFICE - modifies, packages and secretes various molecules

9. LYSOSOMES
Contain digestive enzymes to break down large molecules as well as non-functioning cell parts and cells
Small, membrane-bound organelles formed by Golgi complex

10. LEEUWENHOEK
Looked at living cells in pond water; invented first mini-microscope

11. CENTRIOLES
Used in cell division
Seen in animal cells

12. RIBOSOMES Site of protein synthesis
Can be free (in cytoplasm) or bound (attached to ER)
Produced in nucleolus
Made of RNA and proteins

13. SMOOTH ER Transports materials within and out of the cell
Functions in lipid synthesis ex. cholesterol
No ribosomes attached

14. EUKARYOTES
Type of cell with a true nucleus and membrane bound organelles
Plant, protists, animal and fungi

15. MITOCHONRDRIA
Transfer energy from organic molecules (like glucose) to ATP (cellular energy) during the process of CELLULAR RESPIRATION
Muscle cells have lots of these
Nicknamed the POWERHOUSE
Inner folds called cristae to increase surface area

16. PLANT CELL
Type of cell with a cell wall, chloroplasts and a large central vacuole

17. VIRCHOW
Stated cells come from the division of preexisting cells

18. CELL WALL Made of cellulose
Protects, prevents excess H2O uptake, maintains shape of plant cell

19. ANIMAL CELL Type of cell with lysosomes and centrioles
Lack a cell wall
YOU ARE MADE OF THESE CELLS

20. CHLOROPLASTS Use light energy to make carbohydrates from CO2 and H2O
Contains chlorophyll
Responsible for PHOTOSYNTHESIS

21. CENTRAL VACUOLE Stores water, enzymes, wastes, and other materials
Largest organelle in a plant cell

22. SCHLEIDEN
Stated all plants are made of cells

23. THE CELL THEORY All living things are composed of cells
Cells are the basic units of structure and function in living things
All cells come from preexisting cells

24. SCHWANN
Stated all animals are made of cells

25. CYTOPLASM
Jelly-like material found between the cell membrane and the nucleus
Contains the organelles of the cell

26. NUCLEOLUS
Found inside of the nucleus
Makes ribosomes
