Name two structures found in plant cells but not animal cells. An elodea leaf was mounted in pondwater between a slide and coverslip with a silicon spacer. Elodea, genus of five or six species of submerged aquatic plants in the frog’s-bit family (Hydrocharitaceae), useful in aquariums and in laboratory demonstrations of cellular activities. Wet Mount of an Elodea Leaf Cell . You probably will not see the cells at this power. 6. Use the SCANNING (4x) objective to focus. Using a microscope, it's possible to view and identify these cells and how they are arranged (epidermal cells, spongy cells etc). 4. What structure surrounds the cell membrane (in plants) and gives the cell support. Water will move OUT of the plant, moving from low salt to high salt. The structure of elodea cells also differ from onion cells. Different? Why are there no chloroplast in onion cells? The Elodea plant which normally lives in low salt now finds itself in high salt. Elodea; Water; See information on suppliers here. 7. Obtain a prepared slide of onion cells or prepare one yourself. 5. To do this, place a drop of water towards one end of the slide. Methods. Elodea plants are native to the New World, though a number of species have established themselves as invasive This is the case because the main part of the cell contains the central vacuole which pushes all the cytoplasm and organelles out toward the cell wall. Elodea cells are in two layers of varying sizes; one layer is long and narrow, and the second layer is short and wide. The cell membrane pulls away from the cell … Name three structures found in plant cells AND in animal cells. This is plasmolysis. Eukaryotic cells are structurally complex units that contain several sub cellular components, each typically with its unique function in the activities of the cell. Add a drop of water (hypotonic solution) and a coverslip and observe the chloroplasts (green structures) and the cell walls. Place a coverslip onto the slide. Elodea cells also contain a vacuole, which is filled with a liquid called cell sap that is primarily made up of water. Elodea are common freshwater aquarium plants. B. Pick off an entire healthy looking Elodea leaf, with fingers or small scissors and place it on the microscope slide. Prepare a wet mount of an Elodea leaf with tap water. Using forceps, remove a small leaf from the tip of an Elodea plant and lay it flat in the drop of water. 3. What structures are visible in the elodea leaf cells? Place the Elodea leaf into the drop of water on your slide. Elodea in Tap Water. Cover with a cover slip. 2. Elodea leaf cells with structures labeled . Using the forceps, gently tear off a small piece of a leaf from Elodea. Overview. Make an inference to explain this. Like any other multicellular living thing, leaf structure is made up of layers of cells. Chloroplasts and mitochondria move within Elodea leaf cells; nuclei are also visible as clear, fried-egg-shaped structures. The nucleus of Elodea is usually found somewhere in the perimeter of each cell. Are chloroplast moving or stationary? In what ways are the cells of the onion and elodea similar? Observe the leaf … Students make slides of cells from an onion skin and an Elodea leaf to observe under a microscope, and learn that all organisms are composed of cells.. Part A - Onion Cells. Put a drop of water onto the microscope slide. Viewing the leaf under the microscope shows different types of cells that serve various functions. This activity is from The Science of Microbes Teacher's Guide, and is most appropriate for use with students in grades 6-8.Lessons from the guide may be used with other grade levels as deemed appropriate.
