Description: (100-200 characters) You’ve met the plant’s outer layer — the epidermis. But did you know it also makes waxy sunscreens and grows absorbent arms? In this video, we explore how the epidermis gets clever with special structures like the cuticle and root hairs: 1. Learn how cutin (a waxy chemical) forms the cuticle, a protective layer that blocks UV rays and reduces transpiration. 2. Discover why desert plants have an extra-thick cuticle to save water. 3. Understand how root hairs grow from epidermal cells to boost water and mineral absorption This is Part 2 of our journey into dermal tissues. Whether you're wondering how plants survive the heat or slurp up water from the soil — this one’s for you! Hit play and let’s go beyond the surface. Courses on Khan Academy are always 100% free.
