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

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

` Study Guide for Exam 1 Chapter 1: 1. What is a “microbe”? What groups of organisms are included in this category? Microbes (microorganisms) are minute living things that individually are too small to be seen with the unaided eye the group includes bacteria‚ fungi‚ protozoa‚ and microscopic algae‚ viruses Only minority of microorganisms are pathogenic(disease-producing) 2. What are some of the benefits provided by microbes? Decompose organic waste‚ producers in the ecosystem

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

all plant cells have the same basic eukaryotic organization. Cells contain a nucleus‚ a cytoplasm and subcellular organelles and they are enclosed in a membrane that defines their boundaries.

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). Procedure: Exercise 1: Viewing Prepared Slides To begin this lab experiment I

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
