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.
Leaf surface area is important to measure in plant studies because it provides a quantitative measurement of the leaf's overall size and potential for photosynthesis. Understanding the surface area helps researchers analyze how efficiently plants can exchange gases with their environment, absorb light for photosynthesis, and regulate transpiration. Additionally, leaf surface area data can be used to compare different plant species, assess the impact of environmental factors, and evaluate the overall health and growth of plants.
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.
Most water loss occurs from the lower surface of the leaf because it has more stomata, which are tiny pores that allow water vapor to escape during transpiration. The lower surface is also less exposed to direct sunlight, reducing the risk of excessive water loss through evaporation.
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.
Factors that influence the plant transpiration rate include environmental conditions such as temperature, humidity, wind speed, and light intensity, as well as plant-specific factors like leaf surface area, stomatal density, and plant species.
The formula for transpiration is: Transpiration = (Amount of water transpired) / (Area of leaf surface) * (Time taken)

This phenomenon is called transpiration.
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.

The water evaporates through the stomata during transpiration. The stomata are very small holes on the surface of the leaf.
Most water loss occurs from the lower surface of the leaf because it has more stomata, which are tiny pores that allow water vapor to escape during transpiration. The lower surface is also less exposed to direct sunlight, reducing the risk of excessive water loss through evaporation.
Leaf area duration (LAD) can be calculated by summing the leaf area at each measurement time point throughout the growing season. It is commonly calculated by using the trapezoidal rule to estimate the area under the curve of leaf area over time. This provides an integrated measure of the total leaf area produced by a plant over a specific period.
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.
