According to the Investigation Manual, in a leaf disc assay, disc float in solution because Group of answer choices oxygen gas generated within them increases their net buoyancy. leaf tissue has less mass than the water it displaces. of the extreme surface tension of the water molecules. carbon dioxide gas production displaces them within solution. photosynthesis has not yet begun in the disc.

During the floating leaf disk assay, the leaf disk eventually floats as it photosynthesizes. Why does this occur? a. The leaf disk floats due to oxygen produced during the light independent reactions (i.e., Calvin cycle) b. The leaf disk floats due to oxygen produced during the light dependent (i.e. light) reactions. c. The leaf disk floats due to carbon dioxide produced during the light independent reactions (i.e., Calvin cycle) d. The leaf disk floats due to carbon dioxide produced during the light dependent (i.e. light) reactions.

Explain what is happening (in all appropriate metabolic processes) in the leaf discs exposed to darkness. Which gases are being produced/consumed? Which gas causes the leaf to float?

The floating leaf disk assay serves as a measure of photosynthetic activity because: [2 pt] glucose is the chemical that absorbs light, allowing photosynthesis to occur; oxygen is produced, which causes the leaf disks to float at different times; sodium bicarbonate is the product of photosynthesis; the leaf disks are too small to float upwards.
