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

EXPERIMENT No. 3 Objective :- To prepare a temporary mount of a leaf peel to show stomata. B) Materials required :- Fresh leaves of plant‚ compound microscope‚ glass slides‚ cover slips‚ water‚ glycerine‚ safranine‚ blotting paper‚ needles‚ brush etc. C) Theory :- i) Stomata are minute pore present on the surface of the leaves. ii) Though they are found on both the upper and lower epidermis of the leaf‚ they are more in number on the lower

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

cleaning wipe was placed over the cover slip. 9) The eraser end of a pencil was then taken and the holder pressed down on the tip firmly without twisting the slide or breaking the cover slip. 10) Finally‚ once completed‚ the slide was taken to a microscope for counting. *Prior to the lab‚ two sets of onion root tips were prepared. The control group was treated with water‚ and the experimental group was treated with lectin. Bottles 1 and 3 contained the lectin treated root tips and bottles 2 and

able to conduct the detailed analysis of cultured plates with growth‚ so not results are available for this test. Discussion: For the Feulgen’s/Schiff’s Stain that tests for DNA‚ the samples that contain DNA will show up under a compound light microscope as a magenta color while samples that do not contain DNA will not show up as magenta. A sample of bacteria from an agar plate was used as a control for the DNA test‚ and it showed up as magenta from the Feulgen stain; this confirms that the test
