What is ligule?

How would you recognize the epidermis of a root versus the epidermis of a leaf?
The lower epidermal layer of leaf has many holes (stomata) in it and guard cells surrounding these holes. In the roots the epidermis has many root hairs growing out of it or regions of dead root hairs where over time the roots have grown longer and the old root hairs are no longer needed to capture water. In the upper epidermis of a leaf you would see palisade cells just beneath the epidermal layer and a waxy cuticle just above.
How does the brittle bush adapt to survive in the desert?
in general, brittle bushes in the desert have deep roots to absorb as much water as possible (or is that cacti?) anyway, they have tightly curled leaves that reduce moisture loss. Leaf pubescence (leaf hairs) grow on brittle brush. These leaf hairs reduce the amount of light the plant is able to absorb, therefore limiting the rate of photosynthetic activity.
Are root hairs found mostly on the stomata?
No root hairs are not found on the stomata.
What is the usual functions of the epidermal hairs on a leaf?
to hold the moisture in the leaf
How are leaves used as a means to identifying plants?

Why does water slide off a leaf?
because there are small "hairs" on it that cant absorb water. the plant doesnt absorb water through its leaves, so it just rolls it off instead of soaking it in. i dont know what the hairs actually are, they just look like hairs from up really close
