The stomata on the underside of the leaf regulate transpiration. The leaf surface area helps to estimate the number of stomata, which could speed up or slow the rate of 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.
Does the size of a leaf affect the rate of transpiration?
The more leaves the plant has, the more surface there is for photosynthesis. This means there will be more stomata so the plant can take in more carbon dioxide. This will also result in more water vapour leaving the plant.
Why do coleus have hairs on their lower surface of the leaf?
To stop or slow down transpiration
Why do most water loss occur from the lower surface of the leaf?
the underside of the leaf loses water much faster
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.

How does the structure of a leaf help with transpiration?
Increasing surface area via capillary action
Why the stomata on undersurface of leaf?
To minimize the rate of transpiration from leaf surface
Evaporation of water from surface of the leaf is called?
This phenomenon is called transpiration.
The release of water through openings on the leaf surface?
Transpiration
How do you calculate leaf area duration LAD?
LAD= [(LAI1 + LAI2)/2] x Number of days LAI is Leaf Area Index. That number is usually given, if not it can be found by Leaf Surface Area/Soil Surface Area.

How can you calculate the total leaf surface area expressed in cm2 in mm2?
1 cm2= 100 mm2
Where does water leave the leaf?
The water evaporates through the stomata during transpiration. The stomata are very small holes on the surface of the leaf.
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.
