Cells, organelles and Microscopes
1)
* Ocular-Contains a magnifying lens that focuses the image from the objective into your eye. * Body tube- tube that holds eyepiece and connects the objectives. * Turret- part that holds two or more objective lenses and can be rotated to easily change power. * Objectives- increases the magnification used for viewing. * Stage-Supports dish in correct location to lens.

* Stage clips- holds down the dish containing the specimen. * Diaphragm- controls the amount of light.
* Course focus- focus on the microscope used for focusing the specimen; it moves the stage. * Fine focus- helps the resolution.
* Light- enables the organelle to be seen by being adjusted. * Base- holds up the microscope.

2) Starting at a low power lens gives the widest view and makes it easier to find the specimen. At medium power its not as wide, it’s a little more zoomed in. Finding the specimen at high power, without first centering it in the field of view at low power, is hard because it is very blurry. 1. To measure the resolution you multiply the magnification of the eyepiece by the multiplication of the lens. 3)

* Nucleus- regulates cell activity.
* Nucleolus- contains DNA, assembles Ribosomes.
* Endoplasmic Reticulum Smooth- does the synthesis of lipids. * Endoplasmic Reticulum Rough- is responsible for protein manufacturing. * Vacuoles- accumulates excess water and pumps it out to pores. * Golgi Apparatus- sorts, packages and transports substances. * Vesicles-

* Lysosomes- responsible for digestion of waste materials. * Mitochondria- responsible for the production of ATP (energy). * Chloroplast- responsible for photosynthesis.
* Microtubules-
* Microfilaments-
* Cilia
* Flagella-
* Cytoplasm-

4) Plant and Animal Cells
* Plant cells are rectangular shaped and animal cells are round. * Plant cells have a cell wall...
