However, this increases the chances that some students will be standing around doing nothing and it will increase the time necessary for everyone to observe and draw their specimens. Methylene blue is specifically used in staining animal cells and blood film. This is a good time to demonstrate how to make a wet mount and how to scrape for cheek for cells. (Ans: the vacuole had released its water, allowing the plasma membrane to shrink, pulling all the organelles, including the chloroplasts, closer toward the center). A “typical” Elodea cell is approximately 0.05 millimeters long (50 micrometers long) and 0.025 millimeters wide (25 micrometers wide). If you have sufficient materials and equipment, you could even have 1 student per microscope. Cheek cells, Elodea leaf cell, Yeast cell, Euglena, Paramecium. ... An organism that is made up of more that one cell. in that range, probably 30-50 microns. cut onion into thinnest piece you can. In the wild, it provides a habitat for fish and aquatic invertebrates, as well as food for ducks, beavers and other animals. Field diameter Field diameter is determined by the number of millimeters observed to fit across the diameter of the field of vision. The Elodea cell is rectangular as seen from the side. Possible specimens include any of the motile protozoa, or even the streaming chloroplasts in Elodea cells. The cells are stained with a dye called methylene blue. The nucleus and cell membrane are clearly visible. Oct 12, 2013 - This Pin was discovered by Candice Rogers. Place the Elodea leaf into the drop of water on your slide. At lower magnification, it is usually possible to get both hairs in focus at the same time, but at higher magnifications, when one hair is in focus, the other will be blurry. When studying an Elodea cell under a microscope, it is important to remember that the cell consists of two layers, yet only one of them can be in focus. (Grades 6-8), CCSS.ELA-Literacy.RST.9-10.9 Compare and contrast findings presented in a text to those from other sources (including their own experiments), noting when the findings support or contradict previous explanations or accounts. An optional activity in this lab is to plasmolyze the Elodea cells by adding 10% NaCl. Grains Of Salt & Metric System 6. Without adding 10% NaCl, the chloroplasts will be located near the plasma membrane, which will be indistinguishable from the cell wall, as a dark border around the cytoplasm. Length: 1.5 mm/10 = .15 mm = 150 µm. cell had cell wall,cytoplasm and a nucleus. Cheek cell: Diameter .1 mm. Some chloroplasts, but not all, will be seen, concentrating close to the cell wall. Magnified view (400x) of squamous epithelial cells from the buccal mucosa (cheek cells from inside the mouth). Elodea cell. View full document. What’s Going On? What structures are missing from the root hair cells? At 400x, chloroplasts should be clearly visible in Elodea cells. The chloroplasts are spread throughout the cell both before the salt solution, and after the distilled water is put onto the slide. 1 - Biodiversity in Chicago. You were instructed to make these drawings very carefully, and to meticulously look for how the appearance of the cells changed when the cells were placed in salt water. Elodea cells, unstained. Elodea leaf cells. Salt water has sucked them together. At the magnifications that are generally attainable in the K-12 classroom, many organelles are not visible.
