Pondweed photosynthesis experiment

Pondweed photosynthesis experiment, Biology hl ia - photosynthesis of elodea lab report to find the effect of light intensity on the rate of photosynthesis of canadian pondweed photosynthesis.

Photosynthesis in action move the light source to see how it affects the rate of photosynthesis in pond weed complete the experiment above. Photosynthesis practical - bubbling pondweed in this practical experiment, the rate of photosynthesis is measured by counting the number of bubbles rising from the cut end of a piece of cabomba pondweed this is a much more reliable version of the practical than the frequently used elodea pondweed.

Aim of the experiment to use pondweed to see how light intensity affects the rate of photosynthesis method set up the apparatus as in the diagram leave for five minutes for the pondweed to acclimatise to the new light intensity count the number of bubbles given off in one minute move the light 10 cm further back. Investigating factors affecting the rate of photosynthesis 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.

Demonstrating oxygen evolution during photosynthesis using pondweed watching gas bubble up from a pondweed as it photosynthesises can be a great demonstration or student practical when placed closer to a light source, the rate of bubbling will speed up, and as the pondweed is taken further away, the bubbles will slow down again - an.

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.

Investigating the rate of photosynthesis of canadian pondweed the same water cannot be used for each experiment because if the pondweed has not used up the.

Rate of photosynthesis in pond-weed plan the aim of this activity is to investigate one of the factors that affect the rate of photosynthesis in pond-weed.
