10/3 Warm Up Match the scientist with the theory: C A B E D A. Schleiden B. Schwann C. Hooke D. Van Leeuwenhoek E. Virchow 1. First discovered cells in cork 2. Plant tissues are composed of cells 3. Animal tissues are composed of cells 4. Cells come from pre-existing cells 5. Improved the microscope C A B E D
10/4 Warm Up 1. What is the function of the smooth ER? 2. What is the function of the centrioles? What type of cell are they in? 3. What is the function of the nucleolus? 4. What is the function of the cell membrane? 5. How does the cytosol compare to the cytoplasm? Lipid synthesis, detoxification & calcium regulation Role in cell division; animals ONLY Ribosome production Due to the phospholipids it is selectively permeable Cytoplasm = cytosol (cell gel) + organelles
Practice!
10/5 or 10/6 Warm Up Determine which organelles would have the highest concentration for each scenario. 1. Nerve cells are very active; they need a lot of energy and thus, they have large numbers of __________ in order to be supplied quickly with large amounts of ATP. 2. Pancreatic cells are making large amounts of enzymes, therefore they would need a large number of _________. 3. Immune cells that destroy bacteria with chemicals need an abundance of _________. 4. Testes and ovaries that make steroids (lipids) would have a large amount of______________. mitochondria ribosomes lysosomes Smooth ER
26 B.4B - A person dies in minutes after ingesting cyanide because ATP, the cell’s source of energy, is no longer being synthesized in the cells. What organelle is not functioning? A ribosome B nucleus C mitochondria D rough ER
