Cell Notes
Cell Theory All living things are made of cells Cells are the basic unit of life All cells came from pre-existing cells
Prokaryotes Eukaryotes Cell Simple More complex Smaller Larger Organelles No Nucleus Nucleus No membrane bound organelles Membrane bound organelles Parts: DNA (nucleoid region) DNA (nucleus) Have ribosomes (70s) Have ribosomes (80s) Example: Bacteria Plants, animals, fungi, algae
Organelles in Eukaryotes CELL MEMBRANE: determines what enters/exits NUCLEUS: control center, contains DNA MITOCHONDRIA: converts food to cellular energy (ATP) RIBOSOMES: make proteins (free floating or attached) SMOOTH ER: makes carbs and lipids ROUGH ER: studded with ribosomes, make proteins GOLGI APPARATUS: packages proteins LYSOSOMES: digest old/unwanted materials CENTRIOLES: pull chromosomes apart during division (cell replication)
Organelles in Eukaryotes CHLOROPLAST: photosynthesis (converts CO2 to food using light) VACUOLE: storage CELL WALL: structure
Plant Animal Chloroplast None Cell Wall + Cell Membrane Only Cell Membrane Large Vacuole Small Vacuole
