    en.wikipedia.org/.../Leaf_tissue_structure

    Original - The fine scale structure of a leaf showing the major tissues; the upper and lower epidermis (and associated cuticles), the palisade and spongy mesophyll and the guard cells of the stoma. Vascular tissue (veins) is not shown. Key plant cell organelles (the cell wall, nucleus, chloroplasts, vacuole and cytoplasm) are also shown. Reason

  3. Leaf - Wikipedia

    en.wikipedia.org/wiki/Leaf

    A leaf (pl.: leaves) is a principal appendage of the stem of a vascular plant, [1] usually borne laterally above ground and specialized for photosynthesis.Leaves are collectively called foliage, as in "autumn foliage", [2] [3] while the leaves, stem, flower, and fruit collectively form the shoot system. [4]

  4. Plant stem - Wikipedia

    en.wikipedia.org/wiki/Plant_stem

    The nodes are the points of attachment for leaves and can hold one or more leaves. There are sometimes axillary buds between the stem and leaf which can grow into branches (with leaves, conifer cones, or flowers). [2] Adventitious roots (e.g. brace roots) may also be produced from the nodes. Vines may produce tendrils from nodes.

    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.

    The rosette form is the structure, the relationship of the parts, and the variations within it, as shown in the following study from a herbarium: Dryas octopetala (white dryas, Rosaceae ) has a leaf rosette of leaf blades with a short petiole , slim, egg-shaped leaves with cordate bases with clearly and regularly toothed margins, and single ...

    en.wikipedia.org/wiki/Microphylls_and_megaphylls

    In plant anatomy and evolution a microphyll (or lycophyll) is a type of plant leaf with one single, unbranched leaf vein. [1] Plants with microphyll leaves occur early in the fossil record, and few such plants exist today. In the classical concept of a microphyll, the leaf vein emerges from the protostele without leaving a leaf gap. Leaf gaps ...

  9. Leaf gap - Wikipedia

    en.wikipedia.org/wiki/Leaf_gap

    The leaf is connected to the stem by the leaf trace, which grows through the leaf gap. The leaf gap is a break in the vascular tissue of a stem above the point of attachment of a leaf trace. [1] It exists in the nodal region of the stem as a "gap in the continuity of the primary vascular cylinder above the level where a leaf trace diverges ...
