Palisade cell, or palisade mesophyll cell are plant cells located inside the mesophyll of most green leaves. They are vertically elongated and are stacked side by side, in contrast to the irregular and loosely arranged spongy mesophyll cells beneath them. Palisade cells are responsible for carrying out the majority of the photosynthesis in a ...
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. [2] These layers are called the palisade parenchyma and spongy mesophyll. Palisade parenchyma cells can be either cuboidal or elongated.
Palisade mesophyll cells can contain 30–70 chloroplasts per cell, while stomatal guard cells contain only around 8–15 per cell, as well as much less chlorophyll. Chloroplasts can also be found in the bundle sheath cells of a leaf, especially in C 4 plants, which carry out the Calvin cycle in their bundle sheath cells.
In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf, [1] but in some species, including the mature foliage of Eucalyptus, [5] palisade mesophyll is present on both sides and the leaves are said to be isobilateral.
Granger’s family and team have since confirmed that the 81-year-old rep is indeed at an independent living facility but denied reports that she is residing within the facility’s memory care ...

The cells in the interior tissues of a leaf, called the mesophyll, can contain between 450,000 and 800,000 chloroplasts for every square millimeter of leaf. The surface of the leaf is coated with a water-resistant waxy cuticle that protects the leaf from excessive evaporation of water and decreases the absorption of ultraviolet or blue light to ...
Steam therapy can be particularly effective, says Dr. Mercola: create a steam bath by filling a bowl with hot water, adding a few drops of eucalyptus or menthol essential oil, and placing a towel ...
