  2. Meristem - Wikipedia

    en.wikipedia.org/wiki/Meristem

    Meristematic tissues are classified into three main types based on their location and function: apical meristems, found at the tips of roots and shoots; intercalary or basal meristems, located in the middle regions of stems or leaves, enabling regrowth; and lateral meristems or cambium, responsible for secondary growth in woody plants. At the ...

  3. Tissue (biology) - Wikipedia

    en.wikipedia.org/wiki/Tissue_(biology)

    Meristematic tissues that take up a specific role lose the ability to divide. This process of taking up a permanent shape, size and a function is called cellular differentiation. Cells of meristematic tissue differentiate to form different types of permanent tissues. There are 2 types of permanent tissues: simple permanent tissues

  4. Cork cambium - Wikipedia

    en.wikipedia.org/wiki/Cork_cambium

    It is one of the plant's meristems – the series of tissues consisting of embryonic disk (incompletely differentiated) cells from which the plant grows. The function of cork cambium is to produce the cork, a tough protective material. [1] [2] Synonyms for cork cambium are bark cambium, peri-cambium and phellogen. Phellogen is defined as the ...

  5. Primary growth - Wikipedia

    en.wikipedia.org/wiki/Primary_growth

    The functions of a plant's growing tips – its apical (or primary) meristems – include: lengthening through cell division and elongation; organising the development of leaves along the stem; creating platforms for the eventual development of branches along the stem; [4] laying the groundwork for organ formation by providing a stock of ...

  6. Lateral root - Wikipedia

    en.wikipedia.org/wiki/Lateral_root

    Meristematic Zone: Right above the root cap and contains the "stem cells" of the plant. In this zone, cells are dividing quickly and there is little to no differentiation present. Root Cap: Protective layer of cells that covers the meristematic tissue. The cells in this part of the root have been seen to play a critical role in gravitropic ...

  7. ABC model of flower development - Wikipedia

    en.wikipedia.org/wiki/ABC_model_of_flower...

    The meristem can be defined as the tissue or group of plant tissues that contain undifferentiated stem cells, which are capable of producing any type of cell tissue.Their maintenance and development, both in the vegetative meristem or the meristem of the inflorescence is controlled by genetic cell fate determination mechanisms.

  8. Vascular cambium - Wikipedia

    en.wikipedia.org/wiki/Vascular_cambium

    During secondary growth, cells of medullary rays, in a line (as seen in section; in three dimensions, it is a sheet) between neighbouring vascular bundles, become meristematic and form new interfascicular cambium (between vascular bundles).

  9. Axillary bud - Wikipedia

    en.wikipedia.org/wiki/Axillary_bud

    As the apical meristem grows and forms leaves, a region of meristematic cells is left behind at the node between the stem and the leaf.These axillary buds are usually dormant, inhibited by auxin produced by the apical meristem, which is known as apical dominance.
