Most leaves are coated in a waxy, waterproof substance that renders them hydrophobic, meaning that they repel water.
Some leaves go even further with small bumps called papillae, too small to be seen by the naked eye. The papillae effectively trap bubbles of air, which the water can not displace, and that causes the water to roll off without making contact with the leaf. Think of it kind of like a hovercraft, which uses a pocked of contained air to keep itself above the water, but in reverse.

What exits the leaf during photosynthesis?
Oxygen is given off during photosynthesis.It is during the aerobic cellular respiration of the leaf cells that carbon dioxide is given off.
Why would some leaves need more stomata than others?
Well, stomata are the pores through which leaves breathe. These are also the pores through which transpiration takes place (Transpiration is the loss of excess water- just like in us, only we call it sweating). So if these pores were on the top of the leaf where sunlight falls directly, then there would be a lot of loss of water through evaporation and it is definitely not good to lose so much water. So in order to reduce the chance of losing lot of water, these stomatal pores are in the lower leaf.
Is tulsi leaf simple or compound?
Simple it doesn't have leaflets coming off of a stem!
Do plants give off water or water vapor?
plants give off water so that the water can evaporate and water earth.yes. plants do give off water. the process of plants giving off water is called transpiration. plants transpire to build up tension which then causes water to transport from the roots to the leaves. Then, because they take on more water than they transpire, they have to forcefully expel water. the expelled water is mostly the dew you find on the grass in the morning.hope i answered all your questions, =)
Is a fallen leaf a biotic factor?
no, once it falls off the tree it is no longer living
Why does water roll off the surface of a leaf?
because the leaf is non polar or Because the leaf is coated in lipid molecules
What happenes if you dip a leaf into rainwater?
The leaf has a wax coating, so water will roll off or the leaf would float on the water.
Can a leaf have no waxy surface?
Yes a leaf can not have a waxy surface if it is so adapted. The waxy surface is designed to keep water off, and inside of the leaf. Leaves in the rain forest often have a waxy surface to keep from being constantly saturated in water.
Is this water resistant at all?
The ipod touch has a solid surface, so if water is poured over it then the water will just roll off. If the ipod is submerged in water then water will be able to get inside and may ruin the electronics.
Why is a pencil flat sided?
So it doesn't roll off when you place it on a flat surface.
What reflects off earths surface?
Water.
What happens to temperature when water evaporates off a surface?
This surface become colder.
What is the Difference between the surface and subsurface?
The difference between surface run-off and subsurface run -off is that surface run-off is that when it is precipitation the water goes on the ground like a river and lake. The water that goes on the top of the ground is going to the oceans. The subsurface run-off is that when it is preciptation the water
When water is used to wash off alcohol from a leaf why does the leaf turns dry?
Because the oxygen in water and peroxide in alcohol mix and tiny bubbles form and when they pop air comes out that makes the leaf dry
What is run off from water cycle?
Surface run off is water that runs over the surface of the land. Generally the soil has been infiltrated to full capacity. Channel run off is water in rivers, streams and channels.
Why does water roll off a person's when persons get out of a swimming pool?
Humans are waterproof.
What reflects sunlight off Earth's surface?
Water.
