Web12 nov. 2015 · Many models have been used to assess the relationship between the photosynthetic rate (Pn) and photosynthetically active radiation (PAR), including the exponential function (EF, [ 8, 10 ]), hyperbolic tangent function (HTF, [ 1 ]), nonrectangular hyperbola model (NHM, [ 11, 13 ]), rectangular hyperbolic model (RHM, [ 18 ]), binomial … WebUltimately, the rate of photosynthesis in this experiment is measured through the number of leaves floating every minute. The sooner all the leaves float, the faster the rate of photosynthesis was. With this said, the data can be analysed and further examined to answer the question. Analysis: Purpose of Procedure Analysis: Room Temperature
Web24 sep. 2024 · This measurement is referred to as a P N-C i curve (or more commonly as an A/C i curve, as A is also widely used as an acronym for photosynthetic assimilation of CO 2) and is one of the most common gas exchange analyses undertaken to determine the response of photosynthetic biochemistry to factors such as drought, [CO 2], light … Web28 feb. 2003 · Methods for measuring the rates of photosynthesis and respiration in plants are reviewed. Closed systems that involve manometric techniques, 14 CO 2 fixation, O 2 electrodes and other methods for measuring dissolved and gas phase O 2 are described.
