Cell Organelles What are they and how are plant and animal cells different? Section 3.2
NUCLEUS TheBrain
MitochondriaThe Powerhouse of the Cell More Numerous in Muscle cells
What two cell organelles were once thought to be prokaryotic cells? Mitochondria and chloroplasts! They both are membrane bound and contain their own circular DNA
Cell Membrane • Selectively permeable • Controls what enters and leaves the cell Protein channels Phospholipid bilayer
Ribosomes most numerous organelle Free in cytoplasm or attached on Rough ER Involved in Protein Synthesis
Endoplasmic Reticulum • Involved with protein synthesis • Produces lipids for cell membrane
Golgi Apparatus • Modifies, secretes, and stores chemicals • Processes proteins produced by ribosomes
LysosomesContains digestive enzymesBreaks down old organelles The Janitor of the Cell Only found in animal cells!
Rectangular shape Cell wall Chloroplasts Large central vacuole Circular shape Lysosomes Centrioles Plant CellsvsAnimal Cells
