In order for us to measure the rate of photosynthesis, we needed … Respiration:        oxygen + glucose -> carbon dioxide + water + heat energy, Photosynthesis:    carbon dioxide + water+ light energy -> oxygen + glucose. What is Respiration in Plants. Add a 7 cm piece of Elodea to Tube 2. Demonstration of photosynthesis and cellular respiration in the aquatic plant Elodea using the pH indicator bromothymol blue (BTB). Describe how the rate of photosynthesis would compare to the rate of respiration and use this to explain why the bicarbonate solution turns yellow. It teaches key vocabulary such as leaf, stem, root, xylem, cellulose, chloroplast, photosynthesis and respiration, and the pronunciation. During photosynthesis, plants are using the energy of the sun to build molecules which effectively store this energy (glucose). Teaching Topics. Do air bubbles form everywhere? Photosynthesis occurs on the green parts of the plant that contain chlorophyll. ... Data Table 3: Gross Photosynthesis in Elodea. The hypothesis was, while CO2 is being given off during respiration, it can be re-utilized during photosynthesis. Obtain 3 pieces of Elodea about 6 cm in length and 2 pieces of aluminum foil. ADVERTISEMENTS: Expt. Known for its bright green color and leafy stems, E. densais an excellent oxygenating plant, making it perfect for use in fresh… What observation supports this inference? a. ... Did this experiment support or refute your initialhypothesis. All Rights Reserved. Oxygen and carbon dioxide pass in and out of the stomata in the plants through diffusion. Some of the experiments are: 1.
To accomplish this, the plants were subjected t different light colours (Blue, Green, Red and purple). To Study the ”Primary Photochemical Reaction” of Photo­synthesis 3. All living things use a process called respiration to get energy to stay alive. This colorful picture book is a great introduction to botany. Start studying BIO100: Lab 5 Photosynthesis & Cellular Respiration. Yes; into making glucose 6.Infer Which gas did the snails release? After an hour, observe the plant’s surface. Aquatic plants undergo photosynthesis and cellular respiration much like terrestrial plants. Since these gases are lighter than water, if you shake the plant, the bubbles will quickly rise to the surface and burst. Makino A, Mae T. Photosynthesis and Plant Growth at Elevated Levels of CO2. Although, photosynthesis is atmospheric carbon dioxide is removed and transformed into oxygen and carbohydrates. This lab involves the qualitative measurement of the changes in carbon dioxide concentration associated with respiration and photosynthesis in the freshwater plant Elodea. Experiment – 1: Object: ADVERTISEMENTS: Demonstration of Release of Oxygen during Photosynthesis. This experiment will look at the affect of light intensity on the rate of photosynthesis on Elodea plants. Photosynthesis and cellular respiration are key processes in maintaining this balance. This test can be done with and without snails. 4. Students design an experiment to demonstrate respiration in the Elodea plant. ADVERTISEMENTS: Here is a list of top ten experiments on photosynthesis with diagram. Plants need light to carry out photosynthesis (consume CO 2) 5.Infer When you began the experiment, was there CO 2 in the water? When the plant is submerged in the water, bubbles of oxygen or carbon dioxide released are trapped and they stick on the leaves or petals temporarily. Plants don’t breathe in and out using lungs, but it is an analogy nonetheless. One common way is to gather bubbles of gas given off by an aquatic plant. During respiration, plants consume food to keep plant cells alive while during photosynthesis, plants create their own food.
