single layer of cells
- usually covered in thick waxy
layer for

Four types:
1. Dermal tissue= outermost
single layer of cells
- usually covered in thick waxy
layer for protection against
water loss
- Ex. guard cells on underside of

transport system that moves
water and nutrients throughout
plant
- Ex. ______ and ______ are
channels through which water
and nutrients move
