state an experiment to prove water is necessary for photosynthesis
Answers
Answer:
It is a part of the process of how a plant produces glucose andother sugars in order to live. In order to photosynthesize, a plantneeds water from what is in the air (measured by humidity) or fromwhat it takes from the ground in its roots, or on its leaves whenit rains, and carbon dioxide from the atmosphere. The plant usesthese two elements to produce by products oxygen, which is releasedas a waste product to the atmosphere, and glucose, which is usesfor energy. Specifically, water is needed for photosynthesis because it'selectrons are used to replenish the lost electrons from thechlorophyll in photosystem II. The hydrogens from water are alsoused to make a proton gradient that powers the ATP synthase whichis used to make ATP for the Calvin cycle. The oxygen is a wasteproduct of the process.
Stable isotopes of carbon and hydrogen are useful indicators of the photosynthetic pathway.
