Elodea are … Elodea Leaf. Human errors are not the same as procedural errors. Draw a colored picture of four elodea cells in a cluster. Estimate how many cells you can see under low power __ 8-20 ____ high power _____ 1-2_ _____ This microscope image of a Begonia leaf is stained red in order to see the parts of the cell. Why are you told to gargle salt water when your throat is sore? Compare the structure of various cells for evidence that they are suited to their functions. Label the chloroplasts, cytoplasm, and cell wall of a single cell. 2 1 3 Identify the labeled organelles visible in the cell. Students know the characteristics that distinguish plant cells from animal cells, including chloroplasts and cell walls. Plant Cell Organism Embryo Biology Purple Violet Png Elodea leaf cell ilration from a microscope slide drop of 10 mackenzie zimbrick lab 3 labelling an elodea cell lab manual exercise 1 elodea leaf 400x general biology lab loyola university chicago. Use your textbook to research a complete explanation to your observations. 1. a. Did the Elodea cell change shape? Elodea under the microscope, the chloroplasts are very obvious. � �. Remember, concentration is a calculation of parts of solute per parts of solvent. Why do people say to add salt to a leech to get it to release from your body? Sketch the cell at low and high power. Pick off an entire healthy looking Elodea leaf, with fingers or small scissors and place it on the microscope slide. + a b Refer to "Plant and Animal Cells: The Same, But Different" to help you identify the structures. 5. Solution: 20 g NaCl / 100 ml solution x 100 = 20% NaCl solution Results/Data: Draw what you saw happen to your experimental cell. Methods. Its leaves are only two cells thick, making it possible to easily view those cells and their organelles. Explain a situation where a cell is in an isotonic situation and draw what would happen to a cell in this type of situation. Observe, draw, and label. Label at least two organelles. What adaptations might they need to help them survive in these environments? 2. Compare the placement of the cells in the Begonia to this image of Elodea cells. Late Plasmolysis, Observation of a leaf of the water plant Elodea. 3) Put on a cover slip. Explain a situation where a cell is in a hypotonic situation and draw what would happen to a cell in this type of situation. Basic Animal Cell Structure 1.Cheek Cells a. However, after watering the plant, the cells become reinflated with water and the plant stands upright. Example: Determine the percent composition by mass of a 100 ml salt solution which contains 20 g salt. Chloroplasts are a type of plastid, distinguished by their green color, the result of specialized chlorophyll pigments. 5 Web page: image of Elodea in an aquarium, video of Elodea leaf cells, and video of Elodea leaf cells with structures labeled; image of Elodea cells, one 8.5-inch x 11-inch image per group (.pdf) plastic sheet protectors (optional) metric ruler, one per group Draw conclusions based on the data obtained through your experiment. Which fluid was most likely added to the wet mount. Experimental Design/Procedure: Design an experiment to test your hypothesis. Prepare sketches of a group of Elodea cells under each set of conditions (tap water, 5% salt solution, and 10% salt solution). In plants, choloroplasts occur in all green tissues. Students know cells function similarly in all living organisms. Label its cell membrane, cytoplasm and nucleus. ( �) � � �) K K K ���� ���� ���� ���� ���� ���� ���� � � : Elodea Lab Some background information: A new aquarist came to Petco and purchased a bunch of Elodea for his aquarium. Hypothesis: Hypothesize what will happen to a cell that is well adapted to life in freshwater when it is placed into a saltwater environment. The cells of elodea, which are often classified as waterweeds, photosynthesize because they grow in the presence of sunlight. By placing a piece of tissue or paper towel at one edge (right) and dropping the solution at the edge of the other side (left), the solution is drawn or "wicked" across the specimen.
