In this experiment, the effect of light intensity on rate of photosynthesis was investigated by recording the time taken for the leaf discs. Floating leaf disk assay for investigating photosynthesis pre-lab questions: answer these in your lab notebook before starting the experiment name at least four parameters that will affect the rate of photosynthesis. Areal photosynthesis net photosynthesis per unit area (in seedling, mg c/m2/day) fixed carbon carbon that has been incorporated into sugar by photosynthesis leaf-area index (lai) the ratio of total leaf area to underlying soil area.
The floating leaf disk assay for with the technique they can readily design experiments to of photosynthesis using the floating leaf disk assy. And design an experiment that uses leaf disks to test your ideas create hypotheses about the effects of environmental photosynthesis in leaf discs 1 using a one. An experiment designed by a student should be presented in two parts (where are grana found), or linking photosynthesis to the rising of leaf discs the connection.
Photosynthesis inquiry for this experiment, you will use the floating leaf disk assay for photosynthetic activity of the bicarbonate ions in the leaf. Floating leaf disk photosynthesis lab when the air spaces are infiltrated with a solution the overall density of the leaf disk design an experiment using the. Using the floating leaf disk assay protocol as a tool to measure the rate of photosynthesis, design an experiment to investigate how varying an environmental or plant condition effects the rate of photosynthesis. The purpose of this experiment was to determine the effect of sodium bicarbonate on the rate of photosynthesis of spinach leaf disks hypothesis: the leaf disks placed in the water solution with sodium bicarbonate will float to the top faster and in a higher quantity because the sodium bicarbonate will serve as a source of carbon dioxide for.

Floating leaf disk photosynthesis lab report the center of your respective lab report targets the information on your experiments — as well as lots of the data.
Photosynthesis is a series of reactions in which green plants and cyanobacteria convert the energy of sunlight into chemical bond energy of organic molecules such as monosaccharides cellular respiration is a series of reactions in eukaryotic cells that converts the energy in the bonds of. Investigating factors affecting photosynthesis using leaf discs one of a series of resources from science & plants for schools (saps) investigating key topics in plant biology an enjoyable and reliable practical activity allowing students to compare factors affecting photosynthesis. Independent research leaf disc photosynthesis lab 1 honori yamada biology sl 2 mar/12/11 the effect of the rate of photosynthesis on different leavesintroduction: oppositely from cellular respiration, photosynthesis is a chemical reaction inwhich autotrophs or green plants produce their own food and as a byproduct, theysynthesize glucose and oxygen.
The floating leaf disk assay for investigating photosynthesis introduction: trying to find a good, quantitative procedure that students can use for exploring photosynthesis is a challenge.
