Present your results in a graph. can serve as an indicator of the rate of photosynthesis. The plant was laid in the test tube, soaked in water and sodium bicarbonate. What was the name of the plant you used to study photosynthesis? Experiment 3: Measuring the Rate of Photosynthesis with Floating Leaf Discs. Photosynthesis Lab Answer Key photosynthesi s lab answer key after getting deal. 1. As photosynthesis proceeds oxygen is released into the interior of the leaf, which changes the buoyancy--causing the disks to rise. They compare the rate of net photosynthesis in water vs. a solution of sodium bicarbonate. Be sure to clearly indicate the x and y axes, the units used, and the graph title(s). 3/15/2017 0 Comments Elodea is this plant: To measure the rate of its photosynthesis, we cut the stalk, so that bubbles would appear more easily. In this lab, you will be experimenting with how different variables affect the rate of photosynthesis. As the, graph shows, photosynthesis works best at intermediate temperatures. Set the thermometer to 25°C (Room Temperature) and the light intensity to 20 . Temperature Light intensity CO 2 level Oxygen production Student Exploration: Photosynthesis Lab Plants use some of the oxygen they produce, but most of it is released. Post-Lab Questions. Taking the air out of the spinach circles to be able to measure the rate of photosynthesis Did the rate of photosynthesis increase or decrease due to the independent variable? Depending on the, You answered this question incorrectly. Independent variable - the light intensity (how close the light is). Students are not expected to know the answers to the … Room Temperature/°C (25°C) Temperature of the room is same during the experiment and measured by the thermometer. 1. In this virtual photosynthesis lab, students can manipulate the light intensity, light color, and distance from the light source. El odea branch 2. In this experiment, the leaves will only rise to the surface when enough CO2 and light is present to allow the leaf disks to carry out photosynthesis and produce O2. The apparatus below (Audus micro burette), is used to measure the rate of photosynthesis in plants. Include a brief statement describing why you selected the graphing method you did. [Note: The purpose of these questions is to activate prior knowledge and get students thinking. Since cellular respiration is taking place at the same time, consuming oxygen, the rate that the disks rise is an indirect … The lab allows a user to vary the light intensity and temperature conditions of an aquarium plant and observe how fast it is photosynthesizing. Decide on those 6 trial distances before you start Then measure the DV for each trial Record all data and units in the table on your page. Students can measure the rate over time. “The hypothesis was…” a. 4. Student Exploration Photosynthesis Lab Answers Glucose is a simple sugar that plants use for energy and as a building block for larger molecules. | Course Hero, Inc. Question: Photosynthesis SHORT ANSWER Experiment 1: Measuring The Rate Of Photosynthesis Lab Results 1. Photosynthesis in Spinach Leaves and Respiration in Beans Abstract\u000B Using spinach leaves, we modeled the rate of photosynthesis in controlled environments. & In the Photosynthesis Lab Gizmo™, you can monitor the rate of photosynthesis by measuring oxygen production. and the volume at 2 minutes 30 seconds was 3.6 mL, then the change Time Volume in Gas Syringe (mL) :00:30 00:01:30o :30 00:02:00.

As photosynthesis proceeds, oxygen is released into the interior of the leaf which changes the buoyancy-- causing the disks to rise. Your answer was, According to the graph below, what temperature will result in the highest rate of. Both ATP and NADPH are necessary for carbon fixation.
