Rate of phtosynthesis
Photosynthesis: photosynthesis, process by which green plants and certain other organisms transform light energy into chemical energy. Science fair project which compares the rates of photosynthesis for various light sources which type of light will be best for photosynthesis and why. Count the number of oxygen bubbles given off by the plant in 1 minute period this is the rate of photosynthesis at that particular light intensity. Today, the average rate of energy capture by photosynthesis globally is approximately 130. Lab 5 photosynthesis: why do temperature and light intensity affect the rate of photosynthesis in plants introduction you have learned that green plants have the ability to produce their own supply of sugar through. Does light intensity affect the rate of photosynthesis in elodea plants hypothesis: yes, light intensity does affect the rate of photosynthesis too much light may cause plants to burn out while too little light will not provide enough light for optimal photosynthesis activity.
Lab: exploring the rate of photosynthesis photosynthesis is the process by which plants take carbon dioxide from the atmosphere, add water, and use the energy of sunlight to produce sugar. The rate of photosynthesis can be affected by sunlight, temperature, co2 and o2, and any factor that influences the production of chlorophyll, enzymes, or energy carriers. Autotrophs such as plants capture free energy from the environment through photosynthesis and chemosynthesis the process of photosynthesis occurs in a series of enzyme-mediated steps that capture light energy to build energy-rich carbohydrates the process is summarized by the following reaction. Factors affecting the rate of photosynthesis the main factors are light intensity, carbon dioxide concentration and temperature, known as limiting factors. Photosynthesis has evolved over millions of years - so is it possible for scientists to improve on it teams of scientists from a range of different disciplines from both the us and the uk are working to make photosynthesis more efficient professor janet allen, director of research at bbsrc, said.
Factors affecting the rate of photosynthesis the term rate always involves time, so the rate of photosynthesis can be considered to be how fast photosynthesis takes place. Class practical in this experiment the rate of photosynthesis is measured by counting the number of bubbles rising from the cut end of a piece of elodea or cabomba lesson organisation the work could be carried out individually or in groups of up to 3 students (counter, timekeeper and scribe. When the temperature rises the rate of photosynthesis rises also there is an optimum temperature at which the rate of photosynthesis is maximum. Which things affect the rate of photosynthesis photosynthesis takes place in the leaves of a plant in the leaf there are chloroplast, which contain chlorophyll this chlorophyll absorbs the sun's sunlight. Big idea investigation 5 t95 cellular processes: 2 energy and communication investigation 5 photosynthesis what factors affect the rate of photosynthesis in living leaves.
An increase in the amount of co2 well increase the rate of photosynthesis, carbon dioxide concentration will directly affect the rate of photosynthesis as it is used in the photosynthesis reactionincreased amount of co2 will increase the rate of. Aim the aim of my experiment is to find out how light intensity affects the rate of photosynthesis prediction i predict that as the light intensity increases that the rate of photosynthesis will increase in proportion, so for example if you increase the light intensity from 10cm away to 20 cm. Photosynthesis in leaf disks teacher preparation and background information general information: photosynthesis is a process in which plants convert light energy create hypotheses about the effects of environmental variables on the rate of photosynthesis. The photosynthetic efficiency is the fraction of light energy converted into chemical energy during the following is a breakdown of the energetics of the photosynthesis process from photosynthesis by hall and above about 10,000 lux or ~100 watts/square meter the rate no longer.

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.
- The li-6800 portable photosynthesis system delivers a new experience along with unprecedented capabilities for measuring gas exchange and chlorophyll fluorescence.
- Lab 7: photosynthesis (revised fall 2008) adapted from expmt 7 in biology with computers lab 7 - biol 201- page 1 of 12 lab 7 use of dpip color changes to monitor the rate of photosynthesis.
- Low light intensity lowers the rate of photosynthesis as the intensity is increased the rate also increases however, after reaching an intensity of 10,000 lux (lux is the unit for measuring light intensity) there is no effect on the rate.
- 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, and apply results to current environmental issues.
