Question

write a hypothesis about oxygen being formed in leafs through photosynthesis

Answer 1

Hypothesis: Photosynthesis in plant leaves involves the release of oxygen gas as a byproduct. The oxygen gas is formed during the light-dependent reactions of photosynthesis, in which light energy is absorbed by chlorophyll molecules in the chloroplasts. This excites the electrons, initiating a series of reactions that result in the splitting of water molecules into oxygen gas, protons (H+), and electrons. The released oxygen gas is then diffused out of the leaf through tiny pores called stomata, providing evidence that oxygen is indeed formed in leaves through the process of photosynthesis.
