Hairs that grow from leaf skin
A trichome is a hair that grows out of a plant's skin. Some are made of just one long cell. Others are a short row of cells stacked end to end. Some even branch like a tiny tree or star.
Many grown-up plant hairs are dead and hollow, with tough walls, a bit like your own hair.
You can feel them on lamb's ear, sunflower leaves, tomato stems, and the fuzzy skin of a peach.
Try this
Gently rub a fuzzy leaf or a peach skin with your finger. Then look closely with a magnifying glass. You are feeling thousands of trichomes!
