  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. Leaf - Wikipedia

    en.wikipedia.org/wiki/Leaf

    The products of photosynthesis are called "assimilates". In ferns and most flowering plants, the mesophyll is divided into two layers: An upper palisade layer of vertically elongated cells, one to two cells thick, directly beneath the adaxial epidermis, with intercellular air spaces between them. Its cells contain many more chloroplasts than ...

  4. Spongy tissue - Wikipedia

    en.wikipedia.org/wiki/Spongy_tissue

    Spongy tissue is a type of tissue found both in plants and animals.. In plants, it is part of the mesophyll, where it forms a layer next to the palisade cells in the leaf.The spongy mesophyll's function is to allow for the interchange of gases (CO 2) that are needed for photosynthesis.

    A plant adapted to growing in crevices or hollows, such as in cliff faces. Compare cremnophyte. [28] [29] chimera An individual composed of two or more genetically distinct tissues, most commonly as a result of a graft and sometimes by mutations that occur during cell division or cellular transfers during seed development. chiropterophilous

  6. 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.

  7. C4 carbon fixation - Wikipedia

    en.wikipedia.org/wiki/C4_carbon_fixation

    A: Mesophyll cell B: Chloroplast C: Vascular tissue D: Bundle sheath cell E: Stoma F: Vascular tissue 1. CO 2 is fixed to produce a four-carbon molecule (malate or aspartate). 2. The molecule exits the cell and enters the bundle sheath cells. 3. It is then broken down into CO 2 and pyruvate. CO 2 enters the Calvin cycle to produce carbohydrates. 4.

    Chloroplasts in leaf cells of the moss Mnium stellare. Plant anatomy or phytotomy is the general term for the study of the internal structure of plants.Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure.
