Detailed explanation-1: -The mesophyll can be further broken down into two layers, the palisade layer and the spongy layer, both of which are packed with chloroplasts, the factories of photosynthesis.
Detailed explanation-2: -Answer and Explanation: The two layers of a plant which contain chloroplasts are the spongy mesophyll layer as well as the palisade layer. These two layers combined comprise the mesophyll layer and they are the factories of photosynthesis. The palisade layer contains more chloroplasts than the spongy mesophyll.
Detailed explanation-3: -The palisade mesophyll layer is made up of closely-packed, elongated cells located just below the upper epidermis. They contain chloroplasts and carry out most of the photosynthesis.
