The internal structure of a leaf that has larger air space is?

The internal structure of a leaf with larger air spaces is the spongy mesophyll. The mesophyll is the main tissue inside the leaf, and it is divided into two main layers: the palisade mesophyll and the spongy mesophyll. The palisade mesophyll is located near the upper surface of the leaf and has tightly packed cells that are responsible for carrying out photosynthesis. The spongy mesophyll is located near the lower surface of the leaf and has loosely packed cells with larger air spaces between them. The larger air spaces in the spongy mesophyll allow for the exchange of gases such as carbon dioxide and oxygen between the leaf and the air. This is important for the process of photosynthesis, where the plant uses energy from sunlight to convert carbon dioxide and water into glucose and oxygen. The oxygen produced during photosynthesis is released into the air through the stomata, which are small pores found on the surface of the leaf.
