DENDROLOGY

Detailed explanation-1: -Photosynthesis primarily takes place in the specilised structures called chloroplasts that have chlorophyll present in them. It is the chlorophyll that absorbs light energy from the sun. The leaves contain majority of the chloroplast which absorbs sunlight for the process of photosynthesis to take place.

Detailed explanation-2: -In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.

Detailed explanation-3: -Maize, sugar cane, and sorghum are C4 plants. These plants are economically important in part because of their relatively high photosynthetic efficiencies compared to many other crops.

Detailed explanation-4: -All of the green structures in plants, including stems and unripened fruit, contain chloroplasts, but the majority of photosynthesis activity in most plants occurs in the leaves.
