The first layer, located under the epidermis but about the second layer, is the palisade parenchyma cells. Palisade mesophyll. The mesophyll, consisting of upper and lower palisade layers and median spongy mesophyll, contains cluster crystals about 15–20 μm in diameter. C to expose the mesophyll cells. Gases enter and exit the leaf through the stomata. Happy Labeling! Start studying Function of Organelles within Exocrine Gland Cells of the Pancreas and within Palisade Mesophyll Cells of the Leaf. Wide collections of all kinds of labels pictures online. This is to optimize the collection of light, and maximize the surface area that is exposed to light. Palisade cells are cells found within the mesophyll in leaves of dicotyledonous plants. What is the function of mesophyll? At the level of the veins, the clusters of palisade cells were fewer, usually providing an inadequate sample. In snow gum, both upper and lower mesophyll layers consist of palisade cells (Fig. The largest clusters of cells were found at the same level as the oil glands. Sunday, December 10th 2017. The Mesophyll is the name given two layers of cells inside of the plants leaves. In broad-leaved trees both SO 2 and HF cause collapse of spongy mesophyll cells and those of the lower, stomata-bearing epidermis, followed by injury to palisade cells (Ormrod, 1978).
