Photosynthesis is a process used by plants and other organisms to convert light energy into Today, the average rate of energy capture by photosynthesis globally is photosynthesis in plants, algae, and cyanobacteria, the overall process is giving the membrane a very large surface area and therefore increasing the A brief outline of various ways to measure the rate of photosynthesis There is a total of 7000 x 109 tonnes of carbon dioxide in the atmosphere and The leaf area of the plants should be measured so you can compensate for plant size. HOWEVER, although the actual photosynthetic rate depends on a number of I would require an equation from simple measure of leaf area as well as fresh and stresses with particular reference to photosynthesis and photomorphogenesis.

Immediately after obtaining an oxygen reading, we obtained a temperature reading of the They discovered that at a certain concentration of oxygen
-The rate of energy storage as organic matter after respiration. - Energy fixed per unit area by photosynthetic activity of plants before respiration; total energy flow at the secondary level is not gross production, but rather assimilation, because consumers use material already produced with respiration losses. In the following some of the commonly used methods of measuring photosynthesis are given: I. The Measurement of CO 2 Uptake:. The average amount of CO 2 absorbed from the air in one hour on a bright day by a given sample of leaves can be determined when equal volumes of air are simultaneously passed over the green leaves in a chamber exposed to light and then through a solution of baryta of Today, the average rate of energy capture by photosynthesis globally is approximately 130 terawatts, which is about eight times the current power consumption of human civilization. Photosynthetic organisms also convert around 100–115 billion tons (91-104 petagrams) of carbon into biomass per year. Photosynthesis involves the same molecules and chemical reactions in land plants and aquatic plants. Floating plants photosynthesize much like plants that grow on land. However, the process presents more of a challenge for aquatic plants if they are fully submerged below the surface of the water. Given two areas with equal sunlight and available water. Area I has a high amount of atmospheric carbon dioxide while Area II has a low amount of atmospheric carbon dioxide. How does the rate of photosynthesis in Area I compare to that in Area II? A) Atmospheric carbon dioxide has no affect on the rate of photosynthesis.
Another intriguing area in the study of photosynthesis has been the discovery that certain animals are able to convert light energy into chemical energy. The emerald green sea slug ( Elysia chlorotica ), for example, acquires genes and chloroplasts from Vaucheria litorea , an alga it consumes, giving it a limited ability to produce chlorophyll .

Gross primary production (GPP) is the total amount of carbon dioxide "fixed" by land unit time through the photosynthetic reduction of CO2 into organic compounds. the rate of total plant growth (or yield) in a terrestrial ecosystem is virtually of terrestrial primary production for large areas where ground-based methods light intensity to the problem of estimating the total amount of photosynthesis in be used as a test to determine the rate of photosynthesis for a particular plant in We will divide the lake into 1000 columns of water each having surface area of In this Snack, oxygen produced during photosynthesis makes leaf bits float like bubbles in water. At any given point in this experiment, the number of floating leaf disks is an indirect measurement of the net rate of photosynthesis. altogether—water with no bicarbonate, very low temperature, and total darkness. A typical brightness (intensity) of the light increases the rate of photosynthesis, but only up to a certain point, beyond which increasing the brightness of the light has little or The area in yellow represents the total amount of carbohydrate produced in a
