Detailed explanation-1: -So, the correct option is ‘Stromal lamellae-Synthesis of ATP’.
Detailed explanation-2: -The two photosystems are Photosystem I and Photosystem II. Both these photosystems PS I and PS II are multi-subunit membrane-protein complexes participating in oxygenic photosynthesis. The pigment that is mainly involved in trapping light energy is chlorophyll. Thus, it is called a pigment system or photosystem.
Detailed explanation-3: -Photosynthesis occurs in two stages. Stage I is called the light reactions because it requires sunlight or artificial light. This stage uses water and changes light energy from the sun into chemical energy stored in ATP and NADPH (another energy-carrying molecule). This stage also releases oxygen as a waste product.
Detailed explanation-4: -Chloroplasts are found in all higher plants. It is oval or biconvex, found within the mesophyll of the plant cell. The size of the chloroplast usually varies between 4-6 µm in diameter and 1-3 µm in thickness. They are double-membrane organelle with the presence of outer, inner and intermembrane space.
