ANATOMY Lab 2: Worksheet In the table below, write the major function of each cellular organelle. ORGANELLE Mitochondria Smooth Endoplasmic Reticulum (smooth ER) Rough Endoplasmic Reticulum (rough ER) Golgi Apparatus Cytoskeleton Free Ribosomes Peroxisome Lysosome MAJOR FUNCTION power plant of the cell, site of ATP production synthesis, transport, and storage of lipids, as well as steroid hormones modifies and packages proteins into transport vesicles to be taken to the Golgi apparatus receives materials from RER for modification, sorting, and packaging network of filaments or hollow tubes produces proteins that reside in the cytosol detoxification of harmful substances, converts hydrogen peroxide to water, and breaks down fatty acid molecules is in charge of digestion of all materials in the cell, autophagy, and autolysis Based on the “specialized” function of each of the following cell types, predict which organelle would be present in higher than normal amounts to perform that function. CELL TYPE “ABUNDANT” ORGANELLE 1. Pancreas (makes protein hormones) 1.Rough ER Skeletal muscle cell 2a. Muscle contraction 2b. Calcium needed for contraction 2c. Slow twitch fibers trained for endurance (hint: need more ATP) 3. Phagocytes (clean up and breakdown cellular debris) 2a.Cytoskeleton Liver Cells 4a. Detoxify lipid drugs 4b. Detoxify free radicals 4a.Peroxisome 2b.Smooth ER 2c.Mitochondria 3.Lysosome 4b.Peroxisome ANATOMY 5. Adrenal Medulla (makes lipid hormones) 5.Smooth ER 6. Mucous cell (secretes protein) 6.Golgi Apparatus 7. Red Blood Cell 7.Free Ribosomes
