1 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. C 6 H 12 O 6 + 6O 2 __ _ 6CO 2 + 6H 2 O + 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 6CO 2 + 6H 2 O + energy C 6 H 12 O 6 + 6O 2

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

17 Terms YOURE responsible for looking up Cell membrane Cytoplasm Cilia Flagella Centrioles- theres something special about centrioles
