Textbook Question
Chapter 4, Problem 9TYU
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.

- PART D: CALCULATING THE ACTUAL SIZE OF A CELL. Once you know your microscope's diameter of the field of view, you can now calculate the actual size of your specimen. The ACTUAL SIZE of the specimen is the real size of the cell you are looking at. When you look at the cells through the microscope. the cells look very tiny. It is possible to determine the actual size of the cells you are looking at under LP.MP and HP. We will determine the actual size of a cell u I under HP. Step 1- Look at the cells under HP MAG. Step 2- Pick one cell you want to know the size of. Step 3- Imagine that this cell is placed along the left side of the field of view. (see example) Step 4-Estimate how many cels could fit across the field of view. Step 5- Record your answer Step 6- Use the formula below to calculate the actual size of your cell NOTE: Cells are very tiny therefore; the size of a cell is calculated in micrometers (um) and not mm.

However, each cell is like a machine. It has many parts and each works in concert with the other. In this post, you will demonstrate an understanding of the functions of organelle and how they work together in cells. Pick one cell organelle, describe its structure and function and then discuss how it works with another cell organelle. Don't forget to add a question to get the class engaged in discussion.arrow_forwardA cell is characterized by the presence of a nucleus, many green organelles, a large water-filled vacuole, and a rigid cell wall.
