IB Biology SL III Ryan Martucci Topic: 1 - Cells Date: 9-25-02 Period: 4th Sub-topic: 1.3 - Eukaryotic Cells 1.3.1 1 Draw a diagram to show the ultrastructure of a generalized animal cell as seen in electron micrographs. This drawing is located at the end of this sub-topic. 1.3.2 1 State one function of each of these organelles: ribosomes, rough endoplasmic reticulum(ER), lysosome, Golgi apparatus, and mitochondrion. Pervading most of the cytoplasm is the ER, a labrybnith of membranes forming flattened sacs and tubes that segregate the contents of the ER from the cytosol. The ER takes two forms, rough and smooth. Many proteins are made by ribosomes attached to ER membranes, and the ER also plays a major role in assembling the cell's other membranes. The Golgi apparatus, another type of membranous organelle, consists of flattened sacs active in the synthesis, refinement, storage, sorting, and secretion of a variety of chemical products. Lysosomes, which contain mixtures of...
