Detailed explanation-1: -Leaves are specialized plant organs designed to capture light energy by photosynthesis. This energy drives the fixation of carbon from the atmosphere in photosynthesis.

Detailed explanation-2: -Leaves are the main photosynthetic organs in plants and thus they are eminently important for growth and biomass accumulation.

Detailed explanation-3: -In leaves, cells in the mesophyll (the tissue between the upper and lower epidermis) are uniquely suited to carry out photosynthesis on a large scale. This is due to their high concentration of chloroplasts, which are the sites of photosynthesis. More chloroplasts means more photosynthetic capability.

Detailed explanation-4: -Thylakoids: A membrane bound structure within the chloroplast. Thylakoids consist of a thylakoid membrane surrounding a thylakoid space or lumen. Thylakoids contain chlorophyll and are where photosynthesis takes place.
