What two structures keep a tree leaf from drying out?

Answer 1

waxy cuticle to prevent water loss

Guard cells to close over stomata to prevent water loss

Stomata on the lower surface of most leaves to prevent less water loss by transpiration ( is lower temp, higher humidity)

Sometimes leaves will curl up, to again increase humidity against the leaf surface and try ot stop water loss via transpiration......these are really only leaves in quite sry environments.....also these leaves will tend to have a thicker cuticle and often store water in leaves or stem eg succulents or cacti depending on where you live.

Answer 2

The cuticle, which is a waxy layer on the leaf surface, helps prevent water loss by creating a barrier against evaporation. Stomata, which are tiny pores on the underside of the leaf, can open and close to regulate the exchange of gases and water vapor, helping to control water loss.

Answer 3

leaves have a waxy covering called a CUTICLE, which keeps water in the leaf.

Answer 4

the cuticle and the stomates

Answer 6

water and oxygen
