What is a pore or hole in the leaf that allows air and water vapour in or out?

Hydathode
*
A hydathode is actually a gland that secretes water. A pore through which water vapor leaves the leaf is a stoma (plural stomata), also called a stomate. On typical leaves, most stomata are found on the underside.
You need a microscope to see stomata well. Each stoma lies between two specialized epidermal cells called guard cells.
yes it is the stoma

What kind of climate and weather conditions do you wil cause a high rate of transpiration?
Warm air can hold more water vapour than cold air therefore transpiration will take place more rapidly into warm air.Furthermore, when the sun shines on the leaves,they will absorb heat as well as light which increases the rate of evaporation of water. In moving air ,the water vapour will be swept away from the leaf as fast as it diffuses out.This will speed up transpiration.The air should also be less humid to accept more water vapour.
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
The leaf 's main job then is to make?
The cells of a leaf contain large numbers of chloroplasts, the part of the plant responsible for photosynthesis. The main job of a leaf is to collect sunlight which allows the plant to produce carbohydrates via photosynthesis.
What is fine network of lines on the undersurface of a leaf?
The fine network of lines on the undersurface of a leaf are called Veins. The water and minerals go to every part of the leaf through these Veins.
Why is it an advantage for plants in the shade to have a large surface area?
The plants in the shade develop larger leaves to capture more sunlight but at the same time it invites for more transpiration from larger leaf surface, hence it is an adventure for such plants.
What is the process when water vapour leaves leaf cells?
The process of water vapour leaving the cells in the leaf is called Osmosis.The process of water vapour leaving the Stoma (The leaf) is called Transpiration.
What is the name of the process when the water vapour escapes from the leaf?
Transpiration
Why did you need to calculate leaf surface area in tabulating your results?
transpiration is the loss of water vapour from the leaves of the plant, therefore the bigger the surface area of the leaf, the more water vapour lost from the plant.
What is the name of water vapour escaping a leaf?
The process I think you're speaking of is transpiration. If you can physically see water droplets on the leaf you could also be witnessing guttation, though, this depends on whether you are viewing this during the day or night. If it is indeed guttation, not transpiration, you would be able to see what looks like water droplets on the leaf surface.
What allows air and water into a leaf?
Stomata
Is water vapour passing out of the stomata of the leaf an example of excretion?
No it is not I don't know what it is but it surely isn't that! Your Welcome!
Through which structure of a leaf is most mater vapour lost into the atmosphere?
The stoma on the underside of the leaf
What are openings in the epidermis of a plant that allows air and water to pass in and out of the leaf?
Stomata....
What is the job of the mesophyll of the leaf?
To carry out photosynthesis as the cells contain chloroplasts and the organelles perform photosynthesis. It has a waxy cuticle which is impermeable to water, so the water passes out of the leaves as water vapour.
What happens when the stomatas of a plant are facing the sun?
The guard cells in the stomata will swell and it will cause the pores to be at its widest and CO2 diffuses into the leaf and into the cells and it will be used for photosynthesis. It will also diffuse water vapour from the leaf.
What are stomata or stomate?
Stomatastomata is a pour found on the leaf or stem of a plant which opens and closes to release water vapour and gases into the atmosphere.
What is the stomata on a leaf?
The opening (usually on the underside of a leaf) that allows gas exchange to take place which is essential for respiration but which also looses water.
