If the ph is too high or too low, the rate of photosynthesis will decrease if the ph is just right, the rate will increase to the best possible point photosynthesis. How can the answer be improved. Photosynthesis virtual lab observation: many different factors can affect the rate of photosynthesis such as temperature, light intensity, levels of co.
Study photosynthesis in a variety of conditions oxygen production is used to measure the rate of photosynthesis light intensity, carbon dioxide levels, temperature. Basic products of photosynthesis the rate of photosynthesis is defined in terms of the rate of oxygen production either per unit mass (or area. Please contribute to this project, if you have more information about this term feel free to edit this page. Photosynthesis is the cornerstone of physiological process and the basis of drymatter production in plants photosynthetic rate is an important parameter.
Category: papers title: an analysis and evaluation of data from photosynthesis experiments. Photosynthesis lab what is the effect on the rate of photosynthesis of spinach leaves when they are in an environment of different concentration of carbon dioxide. The photosynthetic rate (rate of co 2 exchange in the leaf chamber) is the difference in co 2 concentration through chamber, adjusted for the molar flow of air per m 2 of leaf area, mol m −2 s −1. Lab: what affects the rate of photosynthesis duration: 45 min class size: up to 32 students general overview: in this lab, students will make hypotheses about.
Biology news & research we expect that our experimental plant will have higher rates of photosynthesis and hence a higher rate of growth than normal plants. Big idea investigation 5 t95 cellular processes: 2 energy and communication investigation 5 photosynthesis what factors affect the rate of photosynthesis. Photosynthesis and respiration 8 determine the rate of photosynthesis for the curve of co2 (ppm) vs time a examine the graph and determine the most linear.
Ap biology investigation on photosynthesis includes background information and instructions for using spinach leaf disks, light, and baking soda to measure the rate. Using an open and a closed system of gas analysis, it was found that co 2 evolution in light and in darkness from plant leaves (sunflower, soybean, watermelon. This activity is a lab where students design an experiment to test the rate of photosynthesis students will analyze data,write a report using the scientific method. A brief overview of c4 photosynthesis in other words, the rate of dark respiration is lower, and the plant has a lower light compensation point. Gross photosynthesis home » gross photosynthesis definition noun (1) the total rate of carbon dioxide fixation supplement synonym: true photosynthesis.
A brief outline of various ways to measure the rate of photosynthesis - including measuring photosynthesis via the uptake of carbon dioxide (eg using immobilised algae), via the production of oxygen in pondweed, via the increase in dry mass, and via the production of carbohydrates. Stages of photosynthesis | back to top photosynthesis is a two stage process the first process is the light dependent process. Your toughest technical questions will likely get answered within 48 hours on researchgate, the professional network for scientists. C based on your data, how does an increase in temperature affect the rate of photosynthesis 11 return to your settings from 9c (25°c, light intensity of 20.
Factors affecting the rate of photosynthesis the main factors are light intensity, carbon dioxide concentration and temperature, known as limiting factors. Carbon dioxide amount, and determine the effects on the photosynthesis rate 5 prepare a graph of the collected data and analyze it materials needed. How does the level of light affect the rate of photosynthesis question date: 2014-11-03: answer 1: in photosynthesis, the energy from the sun is used to turn carbon. Quiz & worksheet - photosynthesis biology lab quiz course light intensity, and found a greater intensity of light meant a faster rate of photosynthesis.
