6. Tim is observing xylem vessel elements under the microscope. He initially used the low power objective (LPO) to search for the vessel elements formed in his specimen (Fig.3 A), he. He then wanted to see the vessel elements in greater detail, so he used the high power objective (HPO). Although he didn't have any trouble in resolving the vessel elements using the HPO he wanted to try using the oil immersion objective (OI0). He noticed that he needed to use the fine adjustment knob to focus at two different groups of vessel elements one at a time (Fig. 5 B and C). He also noted that he cannot completely resolve the specimen under the O10 when it should appear clearer as shown by his instructor previously. A B Figure 5. Vessel elements developed from cassava pith in response to synthetic plant hormones under LPO (A) and OIO (B and C). a Explain why Tim can only focus on one group of vessel elements at a time when he used

1.Why is wavelenth the main limiting factor on limit of resoltuin in light microscopy? 2.Assuming that all other variables remain constant, explain why light of shorter wavelengths will produce a clearer image that light of longer wavelenths. 3. Why aren't the magnification of both ocular lenses of a binocular microscope used to calculate total magnification?
Assume you are observing the diatom pictured in Figure 1 using the 10X lens in a compound light microscope. You move to the 40X lens and then again to the 100X lens by only rotating the turret (remember that the lenses are parfocal), without making any other adjustments to the microscope. c) After making your adjustments, you notice that the midline of the diatom is in focus while the remainder is blurry. Explain, based on microscopy principles, why this has occurred Provide a description of the procedure to prepare an acidic stain of bacteria using Nigrosin as it would appear in the Methods section.
You have a microscope equipped with 10 x oculars and 4 objectives, which exhibit the following characteristics (M, NA): A=(4 x/0.13); B=(20 x/0.4); C=(20 x/0.7); D=(40 x/0.65) Tick the right answers: o Objectives B and C are equivalent. o Objective D will allow more detailed observation than objective C. o To see small structures, you should choose objective D rather than C. o Objective D has a lower resolution than objective C. o To observe large objects, it is better to use objective B rather than objective C
3D dimensionality is a limitation of the compound microscope. Depth of field, DOF, describes dimensionality form top to bottom and can be observed with colored cross threads. Observe the crossed thread slide on low power (4x), then on medium power (10x), then on high power (40x objective magnification). Which crossed fiber is on top? How do you know?
a. Do you open both eyes or close one eye when viewing a specimen under a microscope? Why? Why not? b. In using a compound microscope, do you start with the low power objective (LPO) or the high power objective (HPO)? Why or Why not? c. When using 60X, do you it together with the coarse adjustment knob or fine adjustment knob? d. Why must you slowly turn the fine adjustment knob? e. Is natural light or is artificial light used when using the microscope?
FOV measured at 100x total magnification is 400 micrometers. What is the FOV at 40X total magnification? 2. If FOV is 5 mm and the number of cells in FOV is estimated at 35, what is the cell size in mm? In micrometers?
1. In microscopy, what could be the possible reason why we cannot completely resolve the specimen under the Oil Immersion Objective (OIO) when, in fact, it was taught that the OIO has a resolving poewer? 2. When using the OIO, we can only focus on one group or parts at a time. (that is, the other parts are blurred) Whys is it so?
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?
