Students learn a simple technique for quantifying the amount of photosynthesis that occurs in a given period of time, using a common water plant (Elodea). The below mentioned article includes a collection of ten experiments on photosynthesis for high school. Therefor, it cannot be a limiting factor directly. They use this technique to compare the amounts of photosynthesis that occur under conditions of low and high light levels. In this lab, students will be testing whether or not aquatic plants do photosynthesis in the dark or light, and also testing if they do cellular respiration during the dark or light. Ans. Students will perform two sets of experiments. WATER. The effect of light intensity on photosynthesis can be investigated in water plants. Floating plants photosynthesize much like plants that grow on land. Less than 1 percent water is absorbed by the plant. Sunlight and Photosynthesis in Aquatic Plants. But the water content of the leaf often acts as a limiting factor indirectly. However, the process presents more of a challenge for aquatic plants if they are fully submerged below the surface of the water. The plant I usually use for this experiment is called elodea, which is available at any local pet store in the fish area. Investigating photosynthesis. Create two identical models of an ecosystem with pond water, an aquatic plant, and a snail. Photosynthesis involves the same molecules and chemical reactions in land plants and aquatic plants. They produce carbon dioxide during cellular respiration. Hydrilla plants are aquatic algal plants. To make food, plants need carbon dioxide, water, and sunlight; this process is called photosynthesis. Student Activity Worksheet. In this experiment, the student will place aquatic plants under different colors of light in a solution of bromothymol blue. Use Cabomba or Elodea, which are sold in aquarium shops.. of the plant. These plants can carry out photosynthesis even they are inside water. Ability to perform photosynthesis is the main distinguishing feature between green plants and other organisms on Earth. 4 PS-3850 5 Student Activity Worksheet. Photosynthesis in aquatic plants takes place in the same way as the land plants undergo to produce foods. 1. Read on to know more about how photosynthesis takes place in aquatic plants. 4. Ans. Photosynthesis Lab with Aquatic Plants and Freshwater Algae Overview Photosynthesis is the process by which plants transform light energy into chemical energy for growth, reproduction, and metabolism of the organism. Plant and snail in pond water, in the light. Photosynthesis is the process by which green plants make their own food. Here is a short lab activity to demonstrate the oxygen production of Pond water is a source of Co2 for these plants. Before they begin the experiment, however, students must come up with a well-worded hypothesis to be … Plants use carbon dioxide and produce oxygen gas during photosynthesis. 1 Make sure each lab group member is aware of safety rules and procedures for this lab. Why pond water only should be used for this experiment? The amount of water actually used in photosynthesis is very small. Water is one of the raw materials of photosynthesis. This project is … Photosynthesis happens when a plant absorbs carbon dioxide, nutrients, and water through the holes found in the roots (branches, stem, flowers, leaves, etc.) The byproduct of that process is oxygen, and you can prove it using a simple science experiment!
