  2. Palisade cell - Wikipedia

    en.wikipedia.org/wiki/Palisade_cell

    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 ...

  3. Ground tissue - Wikipedia

    en.wikipedia.org/wiki/Ground_tissue

    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.

  4. Leaf - Wikipedia

    en.wikipedia.org/wiki/Leaf

    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.

  5. Chloroplast - Wikipedia

    en.wikipedia.org/wiki/Chloroplast

    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.

  9. Vascular bundle - Wikipedia

    en.wikipedia.org/wiki/Vascular_bundle

    It forms a protective covering on the leaf vein and consists of one or more cell layers, usually parenchyma. Loosely-arranged mesophyll cells lie between the bundle sheath and the leaf surface. The Calvin cycle is confined to the chloroplasts of these bundle sheath cells in C 4 plants. C 2 plants also use a variation of this structure. [1]
