Chapter 4, Problem 7TYU
SCIENTIFIC INQUIRY In studying micrographs of an unusual protist (single-celled eukaryote) that you found in a sample of pond water, you spot an organelle that you can’t recognize. You successfully develop a method for growing this organism in liquid in the laboratory. Describe how you would go about finding out what this organelle is and what it does in the cell. Assume that you would make use of additional microscopy, cell fractionation, and biochemical tests.

The Size of Cells and Their Components:
a. (a) If you were to magnify a cell 10,000 fold (typical of
the magnification achieved using an electron microscope),
how big would it appear? Assume you are viewing a "typical"
eukaryotic cell with a cellular diameter of 50 um.
You are studying amoebas and paramecia, two different single-celled protozoans. You have at your disposal a standard white light
(known as "bright-field") microscope, a fluorescence microscope, a scanning electron microscope, and a transmission electron
microscope. For each of the following studies, indicate which type of microscope would be most useful.

- Cell Graphic Organizer Please complete the following graphic organizers to the best of your ability. • FIRST SQUARE: Put each component's function in the first square. The function is what the component does in the cell. Please be very detailed in your answer and use your book to help you. SECOND SQUARE: In the second square, please put the type of cell that the component is found in. Although you could talk about prokaryotes vs. Eukaryotes, it would be more important to talk about plant vs. animal cells. Also, if possible, please describe where in the cell this component is found. THIRD SQUARE: In the third square, please make a sketch of the component. Although we are not all gifted artists, please give this a good attempt. You may want to show where it is in the cell, an inside view of the part, or even a combination of both. • FOURTH SQUARE: Finally, relate the function of the cellular component to something at FHS. Make sure that the connection is clear and well described.arrow_forwardCell Graphic Organizer Please complete the following graphic organizers to the best of your ability. • FIRST SQUARE: Put each component's function in the first square.
