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. Sccor1010 prac 2 - photosynthesis photosynthesis - discovering the effect of irradiance and temperature on reaction rate sarah dyer 30085118 partner - elizabeth dyer scott nankervis and martin lee thursday 1130 class introduction - what is the most important process that takes place on earth. Get expert answers to your questions in environmental stresses and photosynthesis and more on researchgate, the professional network for scientists. We can conclude that the et 50 statistic is indirectly proportional to the rate of photosynthesis, the higher the rate of photosynthesis, the smaller the et 50 statistic this is a rather undesirable result.
Start studying photosynthesis learn vocabulary, terms, and more with flashcards, games, and other study tools. However the rate of photosynthesis is usually 30 times the rate of respiration, so plants produce large net quantities of oxygen that is then used by animals that in turn produce co 2 which feeds the plants, in a cycle leaves, cells and chloroplasts. Intensity on the rate of photosynthesis to the canadian pondweed, elodea in the results the pattern is that when the light intensity is higher the readings are generally higher on the graph the less the. Get expert answers to your questions in plant biology, photosynthesis, chlorophyll and carotenoids and more on researchgate, the professional network for scientists. For example, the high rates of c 4 photosynthesis in maize (zea mays) and sugarcane (saccharum officinarum) photosynthesis, grain yield, and nitrogen utilization in rice and wheat amane makino plant physiology jan 2011, 155 (1.
Three factors can limit the speed of photosynthesis - light intensity, carbon dioxide concentration and temperature if you plot the rate of photosynthesis against the levels of these three limiting factors, you get graphs like the ones above in practice, any one of these factors could limit the. Abstract introduction results graphs discussions methodology initial investigation background the effect of co2 concentration on the rate of photosynthesis in spinach leaves by: rafid, safwat, saheeb the overview question hypothesis materials light source straw to stir the solutions procedure 1. Photosynthesis in elodea john hindmarsh photosynthesis and respiration with cabomba pondweed ms cooper - duration: 15:06 ms cooper's igcse biology 36,251 views 15:06 effect of a varying light intensity on rate of photosynthesis-updated - duration: 4:05 biology. 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.
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.
In the photosynthesis investigation, you will compare the photosynthetic light response curve of your leaf to that studied by another group to adequately explain your result in your lab reports, you will need to discuss some of the factors that affect the rate of photosynthesis in a leaf and thus. 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. Ib biology higher level lab report title: investigate the effects of sodium bicarbonate and light intensity on the rate of photosynthesis of green spinach leaves through the observation of floating leaf discs. At low and medium light intensity the rate of photosynthesis is directly proportional to the light intensity as the carbon dioxide concentration increases so does the rate of photosynthesis.
