The reactant molecules, including water, CO2, and light, enter the chloroplast in various ways. For example, water enters the leaves through xylem, which is located in vascular bundles made up of xylem and phloem.
Through the stomata and xylem, respectively, the substrates or reactants like carbon dioxide and water significantly reach the chloroplast in the leaves during photosynthesis. The carbon dioxide that other living things release when they breathe is often used by plants.
We know that plants require water (H2O) and carbon dioxide (CO2) to create food, but where do these reactants come from and how do they get there.
