Stem | Description, Facts, & Types | Britannica
WEBSep 3, 2024 · Stem, in botany, the plant axis that bears buds and shoots with leaves and, at its basal end, roots. The stem conducts water, minerals, and food to other parts of the plant and may also store food or be photosynthetic itself. Learn more about the importance, types, and functions of plant stems.
Plant stem - Wikipedia
WEBA 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.

WEBAug 28, 2024 · Stem Anatomy. The stem and other plant organs are primarily made from three simple cell types: parenchyma, collenchyma, and sclerenchyma cells. Parenchyma cells are the most common plant cells. They are found in the stem, the root, the inside of the leaf, and the pulp of the fruit.

WEBOct 31, 2023 · Stems may be herbaceous (soft) or woody in nature. Their main function is to provide support to the plant, holding leaves, flowers, and buds; in some cases, stems also store food for the plant. A stem may be unbranched, like that of a palm tree, or it may be highly branched, like that of a magnolia tree.

WEBstem, In botany, axis of vascular plants that emerges from the roots, supports the branches, bears buds and shoots with leaves, and contains the vascular tissues (xylem and phloem) that transport water, minerals, and food to other parts of the plant.
Key Differences Between Trees vs Plants - Local Tree Estimates
WEBHeight and Size. One of the most distinctive differences between plants and trees is their size. While plants can grow quickly and expand to cover a significant amount of ground, trees tend to be much larger. Tree canopies can be vast, and the roots beneath the ground can create expansive networks.
