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 many pounds of skin cells do you?
Humans shed a significant number of skin cells daily, with estimates suggesting that an individual can lose about 30,000 to 40,000 skin cells every minute. Over a year, this can accumulate to approximately 8 pounds of skin cells. This process is part of natural skin renewal, as old cells die and are replaced by new ones.

The lower epidermis typically consists of a single layer of cells, mainly containing guard cells, subsidiary cells, and stomata. Guard cells control the opening and closing of stomata to regulate gas exchange and water loss in the leaf. Subsidiary cells provide support to the guard cells in carrying out their function.
