Place excess sodium bicarbonate (NaHCO3) in the water to give a constant saturated solution of CO2. Hydrilla leaf is used in an experiment to test that. Place the lamp (the only light source) at a fixed distance from the plant. Because hydrilla is a small plant and hence easy to handle and also it is a aquatic plant so it is able to breath in water whereas land plants are not. 1. The products of photosynthesis in aquatic plants, basically carbohydrate and oxygen, are used by other organisms living in the same biotic community. Why only hydrilla plant is used in the experiment to prove that oxygen is necessary for the photosynthesis. Increasing the concentration of CO2 increases the rate of photosynthesis. Photosynthesis is the chemical change by which plants use carbon dioxide and water, with the aid of sunlight, to make glucose and oxygen. For demonstration of photosynthesis experiments, usually aquatic plant Hydrilla is used , not any terrestrial plant , why ? (ii) Potassium hydroxide absorbs CO 2 from the surrounding. Find an answer to your question Why only hydrilla plant is used in the experiment to prove that oxygen is necessary for the photosynthesis 1. If bubbles fail to appear, cut off more of the stem and recrush. No wonder hydrilla has become the most invasive aquatic plant in Florida. 1.Rate increases as long as no other factor is rate limiting. To … Students should be thinking about the question they will raise about the photosynthesis experiment and if an investigation can be designed to test their question. (TS: Mar 2015) A: 2. 10. What teacher does Why Hydrilla plant is used in this experiment? This is a simple demonstration that allows your students to observe photosynthesis firsthand. 2. Basic Materials needed for lab group of 3-4 students:-Spinach leaves -4 mm core borer (used to cut holes in cork stoppers, can … Hydrilla can also become established in lakes with high turbidity when others cannot. Pond water is used so that plant gets Co2 dissolved in water. Photosynthesis is the process plants (or photoautotrophs) use to convert energy from the sun, carbon dioxide, and water into food (carbohydrates). What pupil does They can do photosynthesis inside the water. Place a pond weed Elodea upside in a test tube containing water at 25°C. (iv) Incense stick PREVIOUSLY ASKED QUESTIONS 1 Mark Questions 1. Procedure for the experiment Take a beaker and fill 3/4ths of it with pond water. This is an example of a common experiment used to investigate light intensity and the rate of photosynthesis. A. Chlorophyll is necessary for photosynthesis. This experiment could certainly be done with land plants, but using a water plant makes it easier to have a simple way to measure the rate of photosynthesis--the counting of … Relevance . For demonstration of photosynthesis experiments, usually aquatic plant Hydrilla is used , not any terrestrial plant , why ? E. densa, E. canadensis, and Chara offer great aquatic organisms to use for this activity. In this experiment, the relationship between the photosynthesis rate and temperature on Elodea is investigated. To do this, I will place a piece of pondweed in varying light intensities and temperatures, and observe the amount of oxygen being given off. Prepare the following set-up: a. TT A: Hydrilla sprigs + carbon paper wrap b. TT B: Hydrilla sprigs c. TT C: carbon paper wrap d. TT D: none Note: Make sure that the sprigs are of the same developmental stage, length, and leaf size. B. Method: 1. It can photosynthesize in water. Photosynthesis itself is a rapid process of converting the water and sunlight into chemical energy and storing it to the entire plant parts which happens at the noon when the sun bright fully. Physics. It is placed to remove CO 2 within the conical flask. Why is this important? 3. Answer Save. EXPAND Content Hydrilla plant was used in this experiment because it is an aquatic plant. 2 Answers. Books. Why only hydrilla plant is used in the experiment to prove that oxygen is necessary for the photosynthesis - Biology - NCERT Solutions; Board Paper Solutions; Ask & Answer; School Talk; Login ; GET APP; Login Create Account. Pour equal amounts of the solution (20 mL each) in four large test tubes labeled A to D. 2. A2. Dibyani Badajena. Why pond water is used? First fill up a beaker with water and place the hydrilla plant inside the water. photosynthesis to produce the nutrient from water, sunlight, and carbon dioxide (CO 2). Share 4. The function of the sodium bicarbonate is providing carbon dioxide for photosynthesis to occur. (iii) The leaf inside the conical flask would be tested for the presence of starch by the application of iodine. Subject: Biology, asked on … Synonyms include H. asiatica, H. japonica, H. lithuanica, and H. ovalifolica. Photosynthesis Karen F.
