How do you describe a plant stem?
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; it may also store food, and green stems themselves produce food.
What are the characteristics of stems?
Characteristics of Stem
- Stem is the vertically growing axis of the shoot system.
- The vertical growth of the stem is maintained by the apical bud.
- Stem is divisible into nodes and internodes.
- Leaves are developed on the stem at nodes.
- Young stems are green and woody stems are brown in color.
What are the 5 types of stems?
- Different types of stems: axis of a plant.
- Stolon: running stems, which trail above the ground.
- Tuber: subterranean swellings of plant axes.
- Volubilate twining: a stem that will wind around objects for support.
- Section of a bulb: division of a bulb that allows study of the interior.
How do you identify the stem and root of a plant?
Stems have nodes and internodes. Nodes and internodes are not found in roots. Stem branches have a thick cell wall. Root hairs have a thinner cell wall.
What are the different kind of stem in plants?

Unique Properties of All Stem Cells All stem cells—regardless of their source—have three general properties: they are capable of dividing and renewing themselves for long periods; they are unspecialized; and they can give rise to specialized cell types.
What are the morphological features of a stem?
Stem morphology is simple. Its components are nodes (places where leaves are/were attached) and internodes, long or short (in the last case, plant sometimes appears to be stemless, rosette-like). Stems are different by the type of phyllotaxis. The phyllotaxis refers to the arrangement of leaves.

What are the different types of stems in the garden?
Woody stems include young twigs, older branches, and the trunk which provides the main support. Herbaceous stems are stems that are mostly supported by water. If the plant lacks water, the stems bend and fall towards the ground. Most garden plants and vegetables with soft, green stems fall under this category.
What are the characteristics of a strong stem?
It is generally erect, strong and usually grows away from the soil (negatively geotropic). There are several plants in which the stem is weak and it either trails on the ground or twines around a support.
