  3. Plant stem - Wikipedia

    en.wikipedia.org/wiki/Plant_stem

    A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves , flowers and fruits , transports water and dissolved substances between the roots and the shoots in the xylem and phloem , engages in photosynthesis, stores nutrients, and produces new living tissue.

  4. Biomass partitioning - Wikipedia

    en.wikipedia.org/wiki/Biomass_partitioning

    Biomass partitioning is the process by which plants divide their energy among their leaves, stems, roots, and reproductive parts.These four main components of the plant have important morphological roles: leaves take in CO 2 and energy from the sun to create carbon compounds, stems grow above competitors to reach sunlight, roots absorb water and mineral nutrients from the soil while anchoring ...

    It can first be seen on the plant as light-green circles, on the stem or underside of its leaves, that eventually turn brown and form pustules. [1] Rust may cause A. majus to bloom prematurely, sprout smaller flowers, and begin decomposition earlier. [12] Stem rot: A fungal infection, it can be seen as a cottony growth on the stem, low, near ...

  6. Cortex (botany) - Wikipedia

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

    In botany, a cortex is an outer layer of a stem or root in a vascular plant, lying below the epidermis but outside of the vascular bundles. [1] The cortex is composed mostly of large thin-walled parenchyma cells of the ground tissue system and shows little to no structural differentiation. [ 2 ]

  7. Monocotyledon - Wikipedia

    en.wikipedia.org/wiki/Monocotyledon

    Many monocots are herbaceous and do not have the ability to increase the width of a stem (secondary growth) via the same kind of vascular cambium found in non-monocot woody plants. [34] However, some monocots do have secondary growth; because this does not arise from a single vascular cambium producing xylem inwards and phloem outwards, it is ...

  8. Herbaceous plant - Wikipedia

    en.wikipedia.org/wiki/Herbaceous_plant

    "A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; "A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.".

  9. Vinca - Wikipedia

    en.wikipedia.org/wiki/Vinca

    Vinca difformis in habitat, Cáceres, Spain. Vinca plants are subshrubs or herbaceous, and have slender trailing stems 1–2 m (3 + 1 ⁄ 2 – 6 + 1 ⁄ 2 ft) long but not growing more than 20–70 cm (8– 27 + 1 ⁄ 2 in) above ground; the stems frequently take root where they touch the ground, enabling the plant to spread widely.
