  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. Plant cell - Wikipedia

    en.wikipedia.org/wiki/Plant_cell

    Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...

  5. Palisade (pathology) - Wikipedia

    en.wikipedia.org/wiki/Palisade_(pathology)

    In histopathology, a palisade is a single layer of relatively long cells, arranged loosely perpendicular to a surface and parallel to each other. [1] A rosette is a palisade in a halo or spoke-and-wheel arrangement, surrounding a central core or hub. [ 2 ]

  6. C4 carbon fixation - Wikipedia

    en.wikipedia.org/wiki/C4_carbon_fixation

    C 4 photosynthesis reduces photorespiration by concentrating CO 2 around RuBisCO. To enable RuBisCO to work in a cellular environment where there is a lot of carbon dioxide and very little oxygen, C 4 leaves generally contain two partially isolated compartments called mesophyll cells and bundle-sheath cells.

  7. Plant physiology - Wikipedia

    en.wikipedia.org/wiki/Plant_physiology

    A germination rate experiment. Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. [1]Plant physiologists study fundamental processes of plants, such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed ...

  8. Phycobilisome - Wikipedia

    en.wikipedia.org/wiki/Phycobilisome

    In this way, the cells take advantage of the available wavelengths of light (in the 500–650 nm range), which are inaccessible to chlorophyll, and utilize their energy for photosynthesis. This is particularly advantageous deeper in the water column , where light with longer wavelengths is less transmitted and therefore less available directly ...

  9. 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.
