DENDROLOGY

Detailed explanation-1: -Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.

Detailed explanation-2: -In a process called photolysis (’light’ and ‘split’), light energy and catalyst s interact to drive the splitting of water molecules into protons (H+), electrons, and oxygen gas.

Detailed explanation-3: -To summarize, chloroplasts “capture” sunlight energy in two ways. Light ‘’excites” electrons in pigment molecules, and light provides the energy to split water molecules, providing more electrons as well as hydrogen ions.

Detailed explanation-4: -The chloroplast is involved in both stages of photosynthesis. The light reactions take place in the thylakoid. There, water (H2O) is oxidized, and oxygen (O2) is released.
