Figure \(\PageIndex{7}\): This image shows cells in the leaf of an aquatic plant, Elodea. Each cell is filled with small green discs which often appear to line the edges of the cell. These are chloroplasts (four are indicated and labeled in the image). Photo credit: Melissa Ha, CC BY-NC. Figure \(\PageIndex{8}\): A diagram of chloroplast anatomy.
Students can determine the typical Elodea cell size with an actual Elodea leaf and a classroom microscope. Under the Microscope Have students determine the field diameter of the compound microscope objectives.
Introduction: Elodea. Elodea with a zebrafish. Elodea leaf cells. Elodea leaf cells with structures labeled. Supported by a Science Education Partnership Award (SEPA) from the National Center for Research Resources, National Institutes of Health , and the David and Lucile Packard Foundation .
Figure 3.8.1 3.8. 1: Elodea leaf cells. The most obvious of the membrane-bound organelles you will see are the chloroplasts. These numerous, green, disc-like structures are responsible for doing photosynthesis, making food for the plant.
Define cell membrane, cell wall, and chloroplast. Remove an Elodea leaf and place it in the middle of a microscope slide. Using a pipette, drop fresh water on top of the Elodea to cover the leaf.
Prepare a wet mount of one leaf from the water plant Elodea using the water in which it is kept. Observe the cells under normal conditions, and make a sketch of what you see. While observing the leaf under the microscope, wick a solution of 6% NaCl (sodium chloride) across the slide.
Elodea are herbaceous perennials that feature dark green leaves arranged in whorls of two to seven along the stem. Plants are usually dioecious (individuals bear either male or female flowers only) and produce seeds in ellipsoid or oval capsules.
Part 2: Cytoplasmic streaming in Elodea. Elodea is an freshwater, aquatic plant native to the Americas commonly used in aquariums. With leaves only two cells thick. Elodea is a good model to study living plant cells in action. In this experiment, you will see chloroplasts moving in the Elodea cells as they begin to
Pick off an entire healthy looking Elodea leaf, with fingers or small scissors and place it on the microscope slide. Add a drop of water (hypotonic solution) and a coverslip and observe the chloroplasts (green structures) and the cell walls.
Leaves and stems of Elodea canadensis Michx have been characterized morphologically and ultrastructurally. Significant features, such as chloroplast structure and distribution in the different tissues, the transfer cell-like organization of the lower leaf cells, the gas-lacunae of the stem cortical region and the hydrophobic material present in ...
