To stop or slow down transpiration
The stomata are located on the lower surface of a leaf.
A light microscope would be suitable for counting the hairs on the surface of a leaf. This type of microscope can provide sufficient magnification and resolution to observe and count the hairs effectively.
Starch is typically stored in the amyloplasts, which are specialized organelles within the leaf cells of a variegated Coleus plant. These amyloplasts store starch as an energy reserve that can be used by the plant when needed.
There are about 92 stomatas on upper surface and 39 stomatas on the lower surface. In a dorsiventral leaf number of stomata is more on the lower surface hence the above answer may please be verified
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 scientific name of mayana leaf is Coleus blumei.

coleus amboinicus
Starch is typically stored in the amyloplasts, which are specialized organelles within the leaf cells of a variegated Coleus plant. These amyloplasts store starch as an energy reserve that can be used by the plant when needed.
stomata is present on a leaf's lower surface. but in plants that float on water, stomata is present on a leaf's upper surface, and the lower surface is protected by a coating of wax.
The submerged leaf filaments are covered with brown hairs which function as roots for water and nutrients absorption. Sporocarps(i) are borne on submerged leaf filaments.

because clorophyll is there
Leaf hairs, also known as trichomes, serve various purposes in plants. They help reduce water loss by creating a barrier against evaporation, protect the leaf from harmful UV radiation, deter herbivores by making the leaf surface less palatable, and trap moisture and nutrients. Overall, leaf hairs contribute to the overall function of a plant's leaves by aiding in water conservation, protection, and nutrient absorption.
When iodine comes into contact with a coleus leaf, it can be used to visualize starch. Iodine solution turns dark blue or black in the presence of starch, allowing you to see where starch is concentrated on the leaf. This reaction is commonly used in biology experiments to demonstrate the presence of starch in plant tissues.
