Which of the following is an advantage of confocal microscopy over conventional fluorescence microscopy? The interaction of the laser beam with the cell surface allows the imaging of individual macromolecules O Only out-of-focus light enters the microscope lens, making the object appear illuminated against a dark background The use of electrons instead of light to image the specimen results in greatly increased resolving power O Optical sections in a single plane of focus can be visualized at different depths in the specimen The natural contrast of an unstained specimen is enhanced

What is the importance of resolution, magnification and contrast in microscopy
L of Microscopes: 1. If you have a standard ocular lens of 10x what is the true magnification that you are looking at if you are using the 100x objective lens. What is the rule for focusing if you switch to the 40x lens? 2. Calculate the sizes of the following cells. Not all cells are viewed at 40x so use the following table to calculate the size of your cells. 4x 1 reticular unit = .025 mm 10x 1 reticular unit = .01 mm 40x 1 reticular unit-.0025 mm 4 points A) Cell 1 on 10x=8 reticular units B) Cell 2 on 40 x = 28 reticular units mm mm Which one is actually larger? Which one is probably the plant cell? Why?

What does parfocal mean? How does this affect the process of using a microscope? What could happen if your microscope is not parfocal?
Imagine you are using a microscope with 5x eye pieces (instead of 10x like ours). If you change from the 10x objective lens to the 40x objective lens, how does the total magnification change? Group of answer choices: -it is 5 times stronger with the 40x -it is 5 times weaker with the 40x -it is 4 times stronger with the 40x -it is 30 units weaker -it is 30 units stronger -it is 4 times weaker with the 40x
