Palisade parenchyma:. Cross-contamination with the opposite cell type was minimal and both cell types were photosynthetically as active as leaf discs. The palisade parenchyma tissue usually is located on the upper side of the leaf, and the spongy parenchyma on the lower side. 5. In simpler terms, they are known as leaf cells. Both types of cells have chloroplasts and appear in green colour. Columnar cells without intercellular spaces, compactly arranged. 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. Spongy parenchyma cells are loosely arranged; hence, there are a lot of intercellular spaces between cells. De er søyleceller. 6. Also, there are two main types of photosynthetic cells in plant leaves. In comparison to palisade parenchyma, spongy parenchyma contains a low number of chloroplasts. In contrast, spongy parenchyma is the lower mesophyll layer of spherical or ovoid cells with few chloroplasts and very prominent intercellular air spaces. Present in dorsiventral leaves.

On the other hand, spongy parenchyma cells are rounded and loosely packed. 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.. Leaves are the main structural parts of plants that produce food by photosynthesis. Because Mesophyll is ground tissue that occurs between the two epidermal layers. Similarities Between Palisade Parenchyma and Spongy Parenchyma 4. Palisade parenchyma cells and spongy parenchyma cells were isolated separately from Vicia faba L. leaflets. It contains elongated cells arranged in layers with small intercellular spaces. Mesophyll parenchyma cells contain many chloroplasts and are usually arranged in two ways: palisade and spongy.

The elongated palisade parenchyma contains the largest number of chloroplasts per cell and is the primary site of photosynthesis in many plants. 5. Chloroplasts are radially arranged in these cells. Yes ! Palisade and spongy-parenchyma cells were isolated from the leaves of a number of mesomorphic dicotyledons by simply brushing the upper and lower sides, respectively, of the leaves with nylon brushes. Moreover, they have a high number of chloroplasts and they are tightly packed cells. Furthermore, palisade parenchyma is present beneath the upper epidermis, while spongy parenchyma is present beneath the palisade parenchyma towards the lower epidermis.
