See the dictionary meaning, pronunciation, and sentence examples. The palisade parenchyma (also called the palisade mesophyll) aids in photosynthesis and has column-shaped, tightly-packed cells. Thus, it assimilates the chlorophyll pigment and refers as “ Assimilatory parenchyma ”. The irregular spongy parenchyma also contains chloroplasts and facilitates the passage of gases through its many intercellular spaces. Parenchyma is a type of simple permanent tissue that makes a major part of ground tissues in plants, where other tissues like vascular tissues are embedded. The photosynthetic parenchyma of the leaves is known as mesophyll, which is usually divided in two types: palisade and spongy mesophyll. Palisade parenchyma is the upper layer of ground tissue in a leaf, consisting of elongated cells beneath and perpendi-cular to the upper epidermis and consti-tuting the primary area of photosynthesis.
