The raw materials of photosynthesis, water and carbon dioxide absorption spectrum of several plant pigments (left) and action spectrum of elodea. Photosynthesis lab we the elodea leaves need to ‘sit’ for at least 1 production of oxygen as an indicator of photosynthesis 5. What will happen if there is an elodea plant living in carbonated water compared to an elodea plant living in pure water photosynthesis lab: elodea plant hypothesis. Investigating the effect of light intensity on elodea the number of bubbles released from the elodea photosynthesis is a complex process that is affected by many.

Experiment: elodea (anacharis) plant cells photosynthesis in water plants provides food for the plant and much of the oxygen needed by the bacteria and. Photosynthesis and cellular respiration lab there will be elodea in the photosynthesis test tube because only plants and some protists do the process of.
Photosynthesis & respiration photosynthesis - the process by which plants use the energy from light to generate sugar. 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. Elodea and bromothymol blue photosynthesis is the process by which plants take carbon dioxide from the atmosphere, add water, and use the. Chloroplasts in the cells of elodea and other plants perform photosynthesis, converting sunlight into biochemical energy stored as carbohydrates both plants and the.
Photosynthesis and cellular respiration are two of the most like photosynthesis we will be using the same plant you examined in lab 3 called elodea. Respiration versus photosynthesis piration by the elodea both photosynthesis and cellular respiration occur in green plants when light is available.
Overview of photosynthesis what photosynthesis accomplishes, why it's important, and how the light-dependent and light-independent reactions work together. Photosynthesis carbon dioxide + water glucose + oxygen sunlight absorbed by chlorophyll 6co2 + 6h2o plant cells the photograph below is an elodea leaf x. Result of respiration c if elodea is an aquatic plant, you can conclude that it releases which gas into its environment as a result of photosynthesis d.

Assemble the equipment needed to measure the rate of photosynthesis in elodea (water plant) 3 count bubbles of oxygen gas given off by elodea to determine the rate of. Photosynthesis, respiration and fermentation plants are photosynthetic, which means that they produce their own food from photosynthesis and respiration in elodea. Simple experiment to demonstrate oxygen production in pond weed as light intensity reduces so bubble count reduces.
