A stem-and-leaf plot of prime numbers under 100 shows that the most frequent tens digits are 0 and 1 while the least is 9. A stem-and-leaf display or stem-and-leaf plot is a device for presenting quantitative data in a graphical format, similar to a histogram, to assist in visualizing the shape of a distribution.
The upper angle between one part of a plant and another, e.g. the stem and a leaf. axile On an axis; of a placenta, on the central axis of the ovary. axillary Borne in or arising from the axil, usually referring to the axil of a leaf. axis The main stem of a whole plant or inflorescence; also, the line along which this stem extends.
English: This diagram show a specific parts of a leaf that is on a stem. The parts included are: 1. Apex 2. Midvein (Primary vein) 3. Secondary vein. 4. Lamina. 5. Leaf margin 6. Petiole 7. Bud 8. Stem
stem attachment: A round leaf where the petiole attaches near the center, e.g. a lotus leaf perfoliate: perfoliatus: stem attachment: With the leaf blade surrounding the stem such that the stem appears to pass through the leaf perforate: perforatus: leaf surface features Many holes, or perforations, on leaf surface. Compare with fenestrate ...
Cladode – a flattened stem that performs the function of a leaf; an example is the pad of the opuntia cactus. Cladophyll – a flattened stem that is leaf-like and green – used for photosynthesis. Normally such plants have no, or greatly reduced, leaves. Climbing – typically long stems that cling to other objects.
The stem can also be called the culm, halm, haulm, stalk, or thyrsus. The stem is normally divided into nodes and internodes: [2] 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]
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.

A tree structure, tree diagram, or tree model is a way of representing the hierarchical nature of a structure in a graphical form. It is named a "tree structure" because the classic representation resembles a tree , although the chart is generally upside down compared to a biological tree, with the "stem" at the top and the "leaves" at the bottom.
