Question: How does mitosis produce new cells‚ and how is mitosis the same and different? Materials: - Compound microscope - Alliums root slide - Whitefish embryo slide - Power supply Procedure: Refer to page 48 and 49 in the textbook. Results: See attached sheet for drawings of my results. Discussion: Analyze and interpret question 1 and 2 on page 49. 1. The cells in the root tip region of the alliums differ quite a bit from the cells that are found deeper in the root

slide in order to see the different microbes and determine their cellular shape. Introduction The purpose of this lab was to become familiar with the light microscope and how to accurately use it to view specimens. The staining method was used to observe different cellular shapes. The exercises preformed using the light microscope were: magnification‚ slide preparation‚ and staining. The stain used in this lab was methylene blue‚ a common simple stain. The different types of specimens

BIO 131 Lab #2 Drawings of Animal and Plant Cells Instructions: 1. Set up light microscope for use. Handle with care. 2. Obtain a slide of animal cells and observe first under low-power (4X)‚ then under medium power (10X)‚ then finally switch to high-power (40X). 3. Make careful observations of the structure of the cells. 4. Draw what you see under high power on a sheet of paper. Place your drawing in a circle measuring 10-15 cm. Use only pencil‚ draw neat lines‚ do not shade. The title

purposes. Agars main purpose is to act as a growth medium for micro-organisms such as bacteria and fungi. The micro-organisms feed off the nutrients contained in Agar and can be both cultured and observed within it by scientists and the use of a microscope. Using Agar A drop‚ equivalent to10ml‚ of the substance being tested needs to be placed and spread over the Agars surface using a non-absorbent sterile tool (a teaspoon can suffice however a glass rod is preferable). It is important that the experiment
