Procedure for the experiment Take a beaker and fill 3/4ths of it with pond water. Log in. (ii) Potassium hydroxide absorbs CO 2 from the surrounding. Running the Experiment 1. Place excess sodium bicarbonate (NaHCO3) in the water to give a constant saturated solution of CO2. Answer. 1.Rate increases as long as no other factor is rate limiting. Sodium hydrogen bicarbonate was used in this experiment to supply carbon dioxide to the pineapple leaf discs to perform photosynthesis. Synonyms include H. asiatica, H. japonica, H. lithuanica, and H. ovalifolica. Why is hydrilla stem cut underwater in photosynthesis experiment? Pond water is used so that plant gets Co2 dissolved in water. It is placed to remove CO 2 within the conical flask. Biology. Light Attenuation and Photosynthesis. 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. A. Chlorophyll is necessary for photosynthesis. Theresa. Problems with creating sodium hydroxide from sodium (hydrogen) carbonate. Increasing the concentration of CO2 increases the rate of photosynthesis. The products of photosynthesis in aquatic plants, basically carbohydrate and oxygen, are used by other organisms living in the same biotic community. The equation for photosynthesis is as follows: Carbon dioxide + water ->glucose + oxygen. It can photosynthesize in water. 2.CO2. Why is this important? 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. What molecule did the sodium … (iv) Incense stick PREVIOUSLY ASKED QUESTIONS 1 Mark Questions 1. Count bubbles for five minutes. Prepare your own tabular column to get information about food deficiency diseases from a doctor. Some days (or even weeks later), a disk is cut out of the other half of the leaf, dried and weighed. Place a 40 watt lamp 5 cm from the plant. Carbon Dioxide and Light are the factors that I will change in the experiment as they are easy to change and measure. Plants use the same visible light spectrum as humans (wavelengths between 400 and 700 nanometers). 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. Experiment. Photosynthesis is a vital process in the … Why pond water is used? (iii) The leaf inside the conical flask would be tested for the presence of starch by the application of iodine. For demonstration of photosynthesis experiments, usually aquatic plant Hydrilla is used , not any terrestrial plant , why ? (ii) Hydrilla plant twigs. the Rate of Photosynthesis Aim The aim of my experiment is to determine whether intensity of light and temperature would affect the rate of photosynthesis in a plant. This is a simple demonstration that allows your students to observe photosynthesis firsthand. Answer Save. Books. Hydrilla sprigs experiment 1. Place the lamp (the only light source) at a fixed distance from the plant. After one minute, count and record the number of oxygen bubbles rising from the cut end of the stem. 2. Share with your friends. B. Why should the level of photosynthesis increase because sodium bicarbonate was added to the water? ... For this extension, an aquatic algal plant such as a hydrilla must be used as photosynthesis still must take place take place underwater. Fix a leaf of this plant in between the Ganong’s screen.
