Title: To examine an animal and cheek cell using a compound microscope Date: 25th September 2012 Lab Partner: xxxxxxxxxxxxx Objective: The main aim of this experiment was to prepare a wet mount of human cheek cells and a wet mount of plant cells and examine them both under a compound microscope. Introduction: Cells are the basic units of life which make up every structure in the human body. They are the smallest units which are living. All cells contain different organelles which

Magnification and Resolution 1) Define the following terms: Magnification: Resolution: 2) Visible light has a wavelength of 400-700 nm. Calculate the best resolution achievable with a light microscope? Show your working out: 3) If the electron gun produces an electron beam with 2 nm wavelength

Data Gathering Process 9 The Candida albicans placed in three sets will be given definite amount of the Pineapple skin extract soap. The fungus will be studied for five days. The researchers will use a microscope to count if the colony of fungi grew or decreased upon the use of the skin extract. Statistical

Pre-lab questions: 1. Algae belong to what Kingdom? They belong to the Kingdom Protista. 2. What are the three types of multicellular algae? The three types if multicellular algae are chlorophyta which are green algae‚ phaeophyta which are brown algae‚ and rhodophyta which are red algae. 3. Are algae autotrophs or heterotrophs? Algae are autotrophs. 4. What organelle allows plants (and plantlike protists) to photosynthesize? The chloroplasts allow plants and plantlike protists to photosynthesize

Return pillbugs to stock culture. 11b- For this experiment you will use: stereoscopic microscope‚ vials with 3-4 virgin female Drosphila melongastor flies‚ and vials with 3-4 male Drosphila melongastor flies. Set up stereoscopic microscope. Obtain one vial containing females and one with males and tap the male into the female vial. Observe behavior of flies with naked eye. Then use the

female ovum‚ which can be seen with the naked eye. Most cells are much smaller than this‚ and microscopes are required to see them. Ordinary light microscopes‚ such as those you may find in school or college laboratories‚ are quite good for seeing tissues and organs‚ but are not that useful for looking into the inside of an individual human cells. An electron microscope is a very powerful type of microscope that is needed to look inside cells‚ and is necessary to see the detail of cell contents. However

Materials and Methods. -- To conduct this experiment there must be the following; a hemacytometer‚ a Pasteur pipette‚ and a compound microscope. A hemacytometer is a counting chamber to count the number of cells in a known volume. Pasteur pipettes

Aim: Observing pond water. Materials: Microscope‚ slide of pond water‚ protests/monera handouts. Procedure: 1. Collect microscope from trolley. 2. Set up microscope and switch on the microscope light. 3. Collect specimen and handouts. 4. Sketch 4-6 different species on medium power setting. 5. Try to estimate size of cells. Observations: I noticed that there was a lot of activity on the slide. There were many little circle-shaped things that were moving quickly all over the slide. I saw a

Experiment 1- Title: Observing Bacteria and Blood Purpose: The purpose of this experiment is to learn how to use a compound microscope and an oil immersion lens while observing prepared bacterial slides. Additionally‚ it will be necessary to prepare slides so as to observe bacterial cultures from yogurt as well as to observe the composition of blood (i.e. red blood cells‚ white blood cells‚ and platelets).
