Answer: composed of columnar epithelium and extends from the middle of the leaf to
the bottom of the leaf where it connects to the lower epidermis. the cells
of the spongy layer of the epidermis are not as densely packed as those
which exist within the palisades layer. these cells have a lower
concentration of chloroplasts and consiquently do not have the same
photosynthetic activity as the cells that exist in the palisades layer

The spongy layer of a leaf features small air spaces between cells that allow for the exchange of gases in photosynthesis. Together with the palisade the spongy layer makes up the mesophyll of the leaf. Spongy cells of the leaf are loosely packed together and lie between the palisade and the lower epidermis with the air spaces connected to each other and the outside by stomata.
