Spongy mesophyll cells are not packed so tightly together, which allows carbon dioxide and oxygen to reach the palisade cells where they are needed in photosynthesis. Spongy mesophyll cells and guard cells (see below) also get some photosynthetic action.
The mesophyll has two layers. The outermost layer is the palisade layer that is made of tightly packed chloroplasts, and the innermost layer is the "spongy layer" that has air between its cells.
Palisade cells, spongy mesophyll cells, and guard cells contain chloroplasts in leaves. Palisade cells are located in the upper leaf epidermis, spongy mesophyll cells are below the palisade layer, and guard cells surround the stomata.
The spongy layer or mesophyll has many air spaces.
There are 4 layers to the typical leaf; the upper epidermis, palisade layer, spongy layer and lower epidermis. ref http://users.rcn.com/jkimball.ma.ultranet/Biology/Pages/L/Leaf.html
Leaves consist mostly of tissue called mesophyll, which is made up of loosely arranged cells with spaces between them. The spaces are filled with air, from which the cells absorb carbon dioxide and into which they expel oxygen.

The two main types of mesophyll cells found in plant leaves are palisade mesophyll cells and spongy mesophyll cells. Palisade mesophyll cells are located in the upper layer of the leaf and are specialized for photosynthesis, while spongy mesophyll cells are found beneath the palisade layer and aid in gas exchange and the storage of nutrients.
spongy layer
The two types of mesophyll in plant leaves are palisade mesophyll and spongy mesophyll. Palisade mesophyll is located closer to the upper epidermis and consists of closely packed cylindrical cells that are specialized for photosynthesis. Spongy mesophyll is located beneath the palisade layer and consists of loosely arranged cells with air spaces for gas exchange and moisture retention.

Beneath the palisade layer of a leaf is the spongy mesophyll layer. This layer contains loosely packed cells with air spaces between them that allow for gas exchange, such as the intake of carbon dioxide and the release of oxygen during photosynthesis.

The region in the leaf that has air spaces to facilitate the movement of gasses is the mesophyll region. This region is composed of layers of cells.
yes :)
The palisade mesophyll is superior to the spongy mesophyll (in most leaves) which aids in photosynthesis, but also serves a "sun block" to the more sensitive cells the spongy mesophyll.
