Within the sponge parenchyma


The middle part of the leaf contains two layers: the sponge parenchyma and the palisade parenchyma. The sponge parenchyma has cells with a large surface, enabling them to exchange as much gas as possible, while the palisade parenchyma is optimized to absorb as much light as possible.
