A section of rosemary stem, an example of a woody plant, showing a typical wood structure. A woody plant is a plant that produces wood as its structural tissue and thus has a hard stem. [1] In cold climates, woody plants further survive winter or dry season above ground, as opposed to herbaceous plants that die back to the ground until spring. [2]
The first column below contains seed-bearing genera from Stearn and other sources as listed, excluding those names that no longer appear in more modern works, such as Plants of the World by Maarten J. M. Christenhusz (lead author), Michael F. Fay and Mark W. Chase. [4] Plants of the World is also used for the family and order classification for ...
Bark is present only on woody plants - herbaceous plants and stems of young plants lack bark. Tree cross section diagram. From the outside to the inside of a mature woody stem, the layers include the following: [20] Bark Periderm Cork (phellem or suber), includes the rhytidome; Cork cambium (phellogen) Phelloderm; Cortex; Phloem; Vascular ...
Cork cambium of woody stem . It is different from the main vascular cambium , which is the ring between the wood ( xylem ) on the inside (top) and the red bast ( phloem ) outside it. Cork cambium ( pl. : cambia or cambiums ) is a tissue found in many vascular plants as a part of the epidermis .
In botany, the trunk (or bole) is the stem and main wooden axis of a tree, [1] which is an important feature in tree identification, and which often differs markedly from the bottom of the trunk to the top, depending on the species. The trunk is the most important part of the tree for timber production.
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. [1] The stem can also be called the culm, halm, haulm, stalk, or thyrsus. The stem is normally divided into nodes and internodes: [2]
A lignotuber is a woody swelling of the root crown possessed by some plants as a protection against destruction of the plant stem, such as by fire. [1] Other woody plants may develop basal burls as a similar survival strategy, often as a response to coppicing or other environmental stressors.
