They are irregularly shaped cells that have many intercellular spaces that … Earn Transferable Credit & Get your Degree, Get access to this video and our entire Q&A library. Plants have larger vacuoles, chloroplasts and cell walls which animal cells don’t have. The important functions of the spongy mesophyll are: The presence of chloroplast in the spongy mesophyll tissue also helps in performing the photosynthesis. ( Log Out /  The midrib is biconvex.

Structure: Consists of cellulose microfibrils and other polysaccharides. The mesophyll, consisting of upper and lower palisade layers and median spongy mesophyll, contains cluster crystals about 15–20 μm in diameter. 3. Palisade cells are found in the mesophyll of a leaf and their main function is the absorption of light so that photosynthesis can take place. 3.
