On the other hand, the spongy chlorenchyma has cells with huge gaps in distances in order to facilitate aeration. Similarities Between Palisade Parenchyma and Spongy Parenchyma These are oval-shaped parenchymatous cells and are loosely arranged with large air chambers. It contains elongated cells arranged in layers with small intercellular spaces. The difference between Palisade Parenchyma and Spongy Parenchyma are Palisade Parenchyma are present below the upper epidermis in dorsiventral leaf whereas Spongy Parenchyma are present towards the lower epidermis in dorsiventral leaf. The palisade parenchyma tissue usually is located on the upper side of the leaf, and the spongy parenchyma on the lower side. There are spaces between spongy parenchyma cells and they are located beneath the palisade parenchyma. In contrast, spongy parenchyma is the lower mesophyll layer of spherical or ovoid cells with few chloroplasts and very prominent intercellular air spaces. The spongy parenchyma shows larger contact areas as well as cell-to-cell contacts between palisade parenchyma and spongy parenchyma and between spongy parenchyma and cells of the vascular bundles. Present in dorsiventral leaves. In comparison to palisade parenchyma, spongy parenchyma cells have a low number of chloroplasts. 6. Parenchyma cells have a variety of functions: In leaves, they form two layers of mesophyll cells immediately beneath the epidermis of the leaf, that are responsible for photosynthesis and the exchange of gases. In simpler terms, they are known as leaf cells. spongy parenchyma synonyms, spongy parenchyma pronunciation, spongy parenchyma translation, English dictionary definition of spongy parenchyma. 2.

Sengbusch, Peter v. Botany Online: Dermal Tissues, Parenchyma and Assimilation Tissues – Mesophyll, Available here. Chloroplasts are radially arranged in these cells. Because Mesophyll is ground tissue that occurs between the two epidermal layers. Cross-contamination with the opposite cell type was minimal and both cell types were photosynthetically as active as leaf discs. In dicot leaves, spongy parenchyma is found below palisade parenchyma and has spherical or oval cells with large intercellular spaces. So, this is the key difference between palisade parenchyma and spongy parenchyma. Degree in Plant Science, M.Sc.

Thus, lower part one for the leaf is less green. Both palisade parenchyma and spongy parenchyma are found in plant leaves. Also, palisade parenchyma cells are tightly packed without the intercellular spaces, while the spongy parenchyma cells are loosely packed with a lot of intercellular spaces. The palisade parenchyma (also called the palisade mesophyll) has column-shaped, tightly packed cells, and may be present in one, two, or three layers. Photosynthetic parenchyma is commonly found under the epidermis, where light is more intense, and it is abundant in leaves, but also in the cortex of green shoots. Palisade parenchyma cells are present beneath the upper epidermis of dorsiventral leaves. Chloroplasts are highly abundant in the palisade parenchyma tissue. 2.
