Basic Building Block of Life

2. Cell Theory
Cells are the basic units of structure & function in living organisms.
All living organisms are composed of 1 or more cells.
Schleiden: all plants composed of cells
Schwann: all animals composed of cells
All cells come from preexisting cells.
Virchow contributed this.

3. Prokaryotes First life form: Archaea & Bacteria
Note cell wall & cytoplasmic membrane
No membrane-bound organelles
DNA in nucleoid
Ribosomes present
Errors in figure
Flagellum, singular
Cytosol

4. Different Cell Types

5. Eukaryotes Protists, Fungi, Plants, & Animals
Have membrane-bound organelles
Nucleus with nucleolus
Endoplasmic reticulum: rough & smooth
Golgi apparatus
Mitochondrion
Chloroplasts, Chromoplasts, & other plastids
Vacuoles: plants’ 1 central vacuole; animals- many
Vesicles: lysosomes, peroxisomes, glyoxysomes

9. Characterized Animal Cell

14. Things to know for the Exam
Cell types
Structure-function relationship
Form follows function.
Size varies greatly.
Organelles specific for animals vs. plants
Function of all organelles.
Plasma membrane structure & function.
