10. Eukaryotic cells have a nucleus to hold their DNA, and 9. Unjumble the sentences below to form the three tenets of cell theory. a. are made all of cells organisms ________________________________________________________________ b. and basic the cells are unit of things function in all structure living. membrane-enclosed organelles that have specialized functions. Prokaryotic cells have no nucleus around their DNA, no membrane bound organelles, but they still make protein. List three things that eukaryotic and prokaryotic cells have in common. ___________________________ ____________________________ ___________________________ ________________________________________________________________ c. from only cells cells pre-existing come ________________________________________________________________ 1-8 Hints. A eukaryotic cell is like a factory. Eukaryotic cells have a nucleus to hold their DNA, and membrane-enclosed organelles that have specialized functions. Parts of factories have functions that are like the structures in cells. For example, chocolate factories make chocolates, cells make proteins, and both use parts with similar functions. Use the descriptions and diagrams on this page to identify the cell parts and their function on the diagram on the back of this sheet. The chocolate making machine makes the individual chocolates like a ribosome makes proteins. The packaging and shipping center in the chocolate factory wraps the chocolates and loads them on trucks heading to stores like a Golgi apparatus packages and exports proteins from the cell. The generator in the chocolate factory provides usable energy like the mitochondria of the plant cell The recycling area helps the factory breakdown worn-out parts into re-usable pieces like the lysosome in the cell. The walls, doors, and windows of the chocolate factory control what gets in and out of the factory like the cell membrane of the cell. This results in homoeostasis The conveyor belt that moves the chocolates is like an endoplasmic reticulum that helps transport proteins in the cell. The office in the chocolate factory stores the information on how to make the chocolates like a nucleus stores DNA/genetic information about how to make proteins. Directions 2. 3.
