Web1. Chloroplasts (Figs. 295-296), responsible for the photosynthesis of the plants, are the characteristic features of the cells of green plants. ADVERTISEMENTS: 2. Around the chloroplast is present a double membrane envelope. 3. Each membrane of chloroplasst is 35 to 50 Å thick. 4. Many dark-coloured grana are present. Absorbs light energy and converts it into chemical energy. Chloroplast has a structure called chlorophyll which functions by trapping the solar energy and is used for the synthesis of food in all green plants. Produces NADPH and molecular oxygen (O 2) by photolysis of water. Produces ATP – Adenosine triphosphate by … See more It comprises inner and outer lipid bilayer membranes. The inner membrane separates the stroma from the intermembrane space. See more The system is suspended in the stroma. It is a collection of membranous sacs called thylakoids or lamellae. The green coloured pigments called chlorophyll are found in the thylakoid membranes. It is the sight for the process of light … See more Stack of lamellae in plastids is known as grana. These are the sites of conversion of light energy into chemical energy. See more It is a colourless, alkaline, aqueous, protein-rich fluid present within the inner membrane of the chloroplast present surrounding the grana. See more
