The spongy mesophyll is a complex, porous tissue found in plant leaves that enables carbon capture and provides mechanical stability. Unlike many other biological tissues, which remain confluent throughout development, the spongy mesophyll must …
Many plant leaves have two layers of photosynthetic tissue: the palisade and spongy meso- phyll. Whereas palisade mesophyll consists of tightly packed columnar cells, the structure of spongy mesophyll is not well characterized and often treated as a …
Genome size coordinates cell sizes and packing densities throughout the leaf
Maintaining high rates of photosynthesis in leaves requires efficient move- ment of CO2 from the atmosphere to the mesophyll cells inside the leaf where CO2 is converted into sugar. CO2 diffusion inside the leaf depends directly on the structure of …
Characterizing the development, structure, and function of the mesophyll in leaves and flowers
The leaf intercellular airspace (IAS) is generally considered to have high conductance to CO2 diffusion relative to the liquid phase. While previous studies accounted for leaf-level variation in porosity and mesophyll thickness, they omitted 3D IAS …
