  2. Epidermis (botany) - Wikipedia

    en.wikipedia.org/wiki/Epidermis_(botany)

    The epidermis is the outermost cell layer of the primary plant body. In some older works the cells of the leaf epidermis have been regarded as specialized parenchyma cells, [1] but the established modern preference has long been to classify the epidermis as dermal tissue, [2] whereas parenchyma is classified as ground tissue. [3]

  3. Guard cell - Wikipedia

    en.wikipedia.org/wiki/Guard_cell

    Guard cells are specialized cells in the epidermis of leaves, stems and other organs of land plants that are used to control gas exchange. They are produced in pairs with a gap between them that forms a stomatal pore .

  4. Root hair - Wikipedia

    en.wikipedia.org/wiki/Root_hair

    Root hair cells improve plant water absorption by increasing root surface area to volume ratio which allows the root hair cell to take in more water. The large vacuole inside root hair cells makes this intake much more efficient. Root hairs are also important for nutrient uptake as they are main interface between plants and mycorrhizal fungi.

  5. Trichome - Wikipedia

    en.wikipedia.org/wiki/Trichome

    Both trichomes and root hairs, the rhizoids of many vascular plants, are lateral outgrowths of a single cell of the epidermal layer. Root hairs form from trichoblasts, the hair-forming cells on the epidermis of a plant root. Root hairs vary between 5 and 17 micrometers in diameter, and 80 to 1,500 micrometers in length (Dittmar, cited in Esau ...

  6. Ground tissue - Wikipedia

    en.wikipedia.org/wiki/Ground_tissue

    Sclerenchyma is the tissue which makes the plant hard and stiff. Sclerenchyma is the supporting tissue in plants. Two types of sclerenchyma cells exist: fibers cellular and sclereids. Their cell walls consist of cellulose, hemicellulose, and lignin. Sclerenchyma cells are the principal supporting cells in plant tissues that have ceased elongation.

  7. Rhizodermis - Wikipedia

    en.wikipedia.org/wiki/Rhizodermis

    Anatomy of a root tip. 3 is the rhizodermis. Rhizodermis is the root epidermis (also referred to as epiblem), the outermost primary cell layer of the root.. Specialized rhisodermal cells, trichoblasts, form long tubular structures (from 5 to 17 micrometers in diameter and from 80 micrometers to 1.5 millimeters in length) almost perpendicular to the main cell axis – root hairs that absorb ...

  8. Pavement cells - Wikipedia

    en.wikipedia.org/wiki/Pavement_cells

    The main purpose of these cells is to form a protective layer for the more specialized cells below. [1] The arrangement and undulating geometry of these cells are demonstrated to enhance the epidermal tear resistance by extending the path of cracks and hindering their progression along cell interfaces, thereby preserving the plant epidermal ...

  9. Meristem - Wikipedia

    en.wikipedia.org/wiki/Meristem

    Meristematic cells are totipotent, meaning they retain the ability to differentiate into any plant cell type. As they divide, they generate new cells, some of which remain meristematic while others differentiate into specialized cells that typically lose the ability to divide or produce new cell types.
