What does the spongy layer do in plants?
The spongy layer is part of a layer called the mesophyll layer, the other part is called the palisade layer. The mesophyll layer is found just below the upper epidermis and is the part of the leaf where photosynthesis happens. Photosynthesis is the process in which a plant uses carbon dioxide, water, sunlight and a chemical found in the chlorophyll it contains to make starch; a plants food source.
