Detailed explanation-1: -The spongy layer is the more open space found directly below the palisade layer. Within the spongy layer you can see the air pockets as well as the vascular bundle containing the xylem and phloem. Collectively, the area that contains the palisade and spongy layers is known as the mesophyll.
Detailed explanation-2: -Spongy mesophyll-loosely packed cells with large air spaces between them. The air spaces allow movement and exchange of gases, specifically oxygen, carbon dioxide, and water vapor. Spongy mesophyll cells also contain chloroplasts.
Detailed explanation-3: -There are two mesophyll layers in a leaf, the palisade mesophyll layer and the spongy mesophyll layer. Via chloroplasts, organelles that serve as the center of photosynthesis, mesophyll’s role is photosynthesis.
