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 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]
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 ...
Lateral buds – a bud located on the side of the stem, usually in a leaf axil. Late wood – the portion of the annual ring that is formed after the formation of earlywood has ceased. Leaf – the photosynthetic organ of a plant that is attached to a stem, generally at specific intervals. Leaf axils – the space created between a leaf and its ...
He noted the commonality of development between foliage leaves and floral leaves (e.g. petals) and wrote: "In the whole plant, whose parts we wonder at as being, at the first glance, so extraordinarily diverse, I finally perceive and recognize nothing beyond leaves and stem (for the root may be regarded as a stem).
In a leaf, the adaxial surface of the leaf will usually be the upper side, with the abaxial surface the lower side. The sugars synthesized by the plant with sun light are transported by the phloem, which is closer to the lower surface. Aphids and leaf hoppers feed off of these sugars by tapping into the phloem. This is why aphids and leaf ...
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.
