The Cell
Covers CA Standards
1c, 1f, 1g

2. Cell theory 1. Organisms composed of one or more cells
2. Cell is basic unit of organization
3. All cells come from pre-existing cells

3. Two basic cell types

4. Two basic cell types-
Prokaryotes- NO internal membrane-bound structures
Eukaryotes- cells DO have internal membrane-bound structures, called ORGANELLES

5. Prokaryotes
Simple- no nucleus
Small- 1/10 size of a eukaryotic cell
Bacteria

6. Eukaryotes – everything else

7. Organelles- why the separation?
Separation allows multiple chemical reactions at the same time

8. Cells have a function, determined by instructions in nucleus
Cells are like a factory, with different departments contributing to the final product
The departments would be the _________

9. Nucleus Control center Contains DNA Nuclear pores
Chromatin- uncondensed DNA
Nucleolus- produces ribosomes

10. Ribosomes
assemble enzymes & other proteins from the directions of the DNA
DNA only carries instructions for proteins

11. Endoplasmic Reticulum- continuation of outer nuclear membrane.
Smooth ER- makes/stores lipids
Rough ER- ribosomes on surface make proteins

12. Golgi Apparatus- stacks of membrane.
Packages and transports macromolecules (proteins)

13. Mitochondria- supplies energy by breaking down glucose.
Double membrane- folds called cristae.
C6H12O6 + 6O2 __
_ 6CO2 + 6H2O + ATP_

14. Vacuole-temporary storage area- food, enzymes, waste
Lysosome- Digest food, waste, bacteria, -the garbage center. Has hydrolytic enzymes
Cytoskeleton- framework for internal support

15. Plant cells Chloroplasts- contains the green pigment chlorophyll
Traps energy in sunlight for photosynthesis
6CO2 + 6H2O + energy
C6H12O6 + 6O2

16. Plants have a cell wall- animal cells do not.
Made of cellulose

17. Terms YOU’RE responsible for looking up
Cell membrane
Cytoplasm
Cilia
Flagella
Centrioles- there’s something special about centrioles
