Microscopes

Let’s give it a try ... 1 – Turn on the microscope and then rotate the nosepiece to click the red-banded objective into place. 2 – Place a slide on the stage and secure it using the stage clips. Use the coarse adjustment knob (large knob) to get it the image into view and then use the fine adjustment knob (small knob) to make it clearer. 3 – Once you have the image in view, rotate the nosepiece to view it under different powers. Be careful with the largest objective! Sometimes there is not enough room and you will not be able to use it! 4 – When you are done, turn off the microscope and put up the slides you used.

You do not need to use the stage clips when viewing wet-mount slides! How to make a wet-mount slide … 1 – Get a clean slide and coverslip from your teacher. 2 – Place ONE drop of water in the middle of the slide. Don’t use too much or the water will run off the edge and make a mess! 3 – Place the edge of the cover slip on one side of the water drop. 4 - Slowly lower the cover slip on top of the drop. Cover Slip Lower slowly You do not need to use the stage clips when viewing wet-mount slides! 5 – Place the slide on the stage and view it first with the red-banded objective. Once you see the image, you can rotate the nosepiece to view the slide with the different objectives.

Virtual Lab Worksheet

Skeletal Muscle Cell Structure and Function Multinucleated because they consist of several cells that have fused together. Contain many mitochondria because they require a lot of energy Contain the protein filaments (myosin and actin) which are responsible for the muscle contraction.

White Blood Cell Structure and Function A normal lymphocyte has a large, dark-staining nucleus with little to no cytoplasm if you think of the cytoplasm as a factory then what the cell needs to produce decides how big the factory/cytoplasm needs to be The ribosomes are involved in protein synthesis  generate large quantities of cytokines and immunoglobulins

Pancreatic Cell Structure and Function These exocrine cells show a strongly basophilic cytoplasm that represents the area occupied by the rough endoplasmic reticulum. The apical side of the cells is filled with zymogen granules that contain a variety of digestive enzymes  duodenum
