Stem: The main axis of a plant, supporting leaves, flowers, and fruits and transporting water and nutrients.
Think of the stem as the plant’s highway system, connecting the roots to the leaves and flowers. The sturdy structure holds everything upright, like a botanical skyscraper. Imagine a sunflower’s thick, hairy stem, or the slender, elegant stem of a rose.
Understanding stems is crucial for tasks like pruning, propagation, and even harvesting in a home garden. You’ll prune stems to shape plants, take stem cuttings to grow new ones, and harvest vegetables like asparagus or rhubarb by cutting the stems. Also, stems can be the location of plant problems. If you see discoloration or damage on a stem, it could be a sign of disease or pests.
Ultimately, the stem is a vital part of a plant’s anatomy, crucial in its growth and survival. It’s more than just a stick; it’s a lifeline, a support system, and a conduit for life.
