Investigating photosynthesis – gas exchange photosynthesis can be investigated to show gas exchange at different light intensities making oxygen the production of oxygen by photosynthesis is most easily seen in water plants such as elodea and cabomba the number of bubbles released in a given time can be. Read this full essay on light wavelength effect on the photosynthetic rate of elodea introduction:the rate of photosynthesis varies greatly with changes in. Like other plants, elodea gets its energy from photosynthesis photosynthesis uses sunlight and other elements to manufacture food for the plant the food is essential in keeping the elodea plant alive and healthy photosynthesis also generates dissolved oxygen in the water, which fish need to survive elodea may not. Elodea is a common freshwater angiosperm found throughout much of northern north america the leaves are only two cells thick, making it very simple to view the photosynthetic cells unlike other plants, its epithelial cells carry out photosynthesis other plants relegate photosynthesis to the internal. Profile how does this weed affect you leafy elodea is a submerged aquatic perennial plant that thrives in shallow, nutrient-rich, slow-moving or stationary water to depths of around seven metres more cold tolerant than many other aquatic weeds, it thrives in southern australia leafy elodea was traded as an aquarium. Elodea (canadian pond weed) is the aquatic plant that has been used traditionally in the classroom to demonstrate oxygen evolution in the process of photosynthesis in theory, when elodea is placed in a solution of sodium hydrogencarbonate in the presence of light of appropriate intensity, the elodea will photosynthesise.
Therefore, having more plants in an aquarium can help to lower nitrate levels in the water this also means less algae growth and less frequent cleaning of the tank the gills of fishes absorb oxygen from the water and produce carbon dioxide plants living in the water need the carbon dioxide for photosynthesis and growth. 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. To determine how carbon dioxide cycles through a biological system by performing the “carbon transfer through snails and elodea” lab activity procedure: read through the background information and purpose create your own question for what you are investigating in this experiment problem (in question form): how.
Photosynthesis this virtual experiment was developed by the university of reading in partnership with syngenta main sub 100% measuring the rate of photosynthesis of elodea sample of pond weed use the ruler to measure the distance between the light and the sample light drag the slider below to move the. In contrast, rates of photosynthesis and respiration in e nuttallii (jones et al, 2000) and e canadensis (simpson et al, 1980) under different conditions of ph, o2 and dissolved inorganic carbon, appear quite similar in addition, james et al (1998) demonstrated that ph tolerance by the two species is also comparable.
Science fair project that examines how light wavelengths affect photosynthesis in the aquatic plant: elodea. Photosynthesis karen f adams burnside scholastic academy 650 east 91st place chicago il 60619 312-535-3300 objectives: (adaptable to grade levels 6- 9) the student will: 1 observe evidence of photosynthesis in a water plant 2 assemble the equipment needed to measure the rate of photosynthesis in elodea. The affect of light on photosynthesis can be investigated using the experimental setup shown a water plant such as elodea pond weed or cabomba pond weed is placed upside in a test tube containing water the pond weed is weighted down with a paperclip to ensure it remains fixed in position the test tube is placed in.
