Chloroplasts are highly abundant in the palisade parenchyma tissue. Privacy Policy Difference between Palisade parenchyma and Spongy parenchyma. Summary. Leaves are the main structural parts of plants that produce food by photosynthesis. Spongy parenchyma cells are loosely arranged; hence, there are a lot of intercellular spaces between cells. 1. (adsbygoogle = window.adsbygoogle || []).push({}); Copyright © 2010-2018 Difference Between. Cross-contamination with the opposite cell type was minimal and both cell types were photosynthetically as active as leaf discs.

Complete information about the anatomy of dorsiventral leaf, Short essay on Parenchyma of Simple Tissues. Degree in Plant Science, M.Sc. The photosynthetic parenchyma of the leaves is known as mesophyll, which is usually divided in two types: palisade and spongy mesophyll. 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. The key difference between palisade parenchyma and spongy parenchyma is that palisade parenchyma consists of columnar cells which are compacted tightly below the upper epidermis of a leaf while spongy parenchyma consists of rounded cells which are loosely arranged below the palisade parenchyma. Palisade parenchyma cells and spongy parenchyma cells were isolated separately from Vicia faba L. leaflets. The irregular spongy parenchyma also contains chloroplasts and facilitates the passage of gases through its many intercellular spaces.

A generalized plant cell type, parenchyma cells are alive at maturity. Palisade cells are plant cells located on the leaves, right below the epidermis and cuticle. 4. The main parenchyma tissues are: Chlorenchyma: Cells which have chloroplast and perform photosynthesis The mesophyll cells in leaves which differentiate into palisade and spongy cells; In the other green parts of the plants like stems, sepal etc. In contrast, spongy parenchyma is the lower mesophyll layer of spherical or ovoid cells with few chloroplasts and very prominent intercellular air spaces. Because Mesophyll is ground tissue that occurs between the two epidermal 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. Chloroplasts are radially arranged in these cells. Other articles where Palisade parenchyma is discussed: angiosperm: Leaves: …divided into two regions: the palisade parenchyma, located beneath the upper epidermis and composed of columnar cells oriented perpendicular to the leaf surface, and spongy parenchyma, located in the lower part of the leaf and composed of irregularly shaped cells.
