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