Draw the slide under 400X. Indicate the cell type, magnification, and estimate the cell size. 14. Elodea 1. Prepare a wet mount of an Elodea leaf (Anarcharis). You will use one glass slide and cover slip for this entire lab. After preparing each slide, remove the specimen and throw it into the trash. Wash the slide in the sink. Dry the slide with a paper towel very carefully and pat the cover slip dry so that the plastic does not...

LABORATORY 5: WORKSHEET NAME: SECTION: DATE INSTRUCTOR LEARNING CHECK EXERCISES 1. When you view your specimen, it is difficult to see because it looks too dark. What part of the microscope might you adjust to correct this? light condensor 2. When you view your specimen it is slightly out of focus, what part of the scope might you adjust to correct this? Fine adjustment Knob. 3. Explain the effect of an increase in magnification on the field of view, and...

5. For this part of the lab you will be observing a whitefishblastula under the microscope. A blastula is a developmental stagein many animals. It occurs shortly after fertilization and theformation of the zygote. It is the “ball of cells” stage ofdevelopment, where cells are dividing rapidly to form themulticellular organism. Note: In this simulation early and lateprophase are combined into one stage: prophase. 1. Go to theVirtual Microscope (Links to an external...

1. Fill out the following table by indicating which general technique (light microscopy (LM) or electron microscopy (EM]) could be used to observe each structure or phenomenon. Put "no" in the box if the technique could not be used. If light microscopy can be used, name one technique (bright-field, phase-contrast, fluorescence, etc.) that you think would be effective. You will find some useful information in Appendix 1 of this manual and Chapter 18 of your textbook. Structure or phenomenon Could...

Unit 3 Study Resource Meiosis • Process by which diploid cells create haploid cells NOT part of the cell cycle > only some cells ever undergo meiosis During meiosis I, hom*ologous chromosomes line up to allow them to be separated into two new cells o They can become "tangled" during this phase, which leads to crossing-over (rearranging the alleles) O Result of meiosis I is two non-identical haploid cells Meiosis Il looks very similar to mitosis, in that sister chromatids...

1. Label the microphylls and strobili in the Figure 1 below. Figure 1. Lycopodium sp. Examine the prepared slide of a mature Lycopodium strobilus. (See text Figure 17-16, pages 406 and 407.) Note that Lycopodium, like most species in the Lycopodiaceae, is hom*osperous and only produces one type of spore 2. Label the spores in Figure 2 below. Figure 2. Lycopodium strobilus 1.s. 3. Given that Lycopodium is hom*osporaus, would you expect its gametophytes to be unisexual or bisexual? Explain...
