the top side is normally brighter with semi-visible veins. the underside is normally darker with very visible veins.
The stoma on the underside of the leaf
The cuticle on the upper surface of a leaf helps to reduce water loss through evaporation and protect the leaf from damage. Since the underside of the leaf is not exposed directly to sunlight and does not play a major role in gas exchange, it does not have a thick cuticle layer.
The breathing hole on the underside of a leaf is called a stomata. Stomata are tiny pores that allow for the exchange of gases such as oxygen and carbon dioxide between the leaf and the surrounding environment. This exchange is crucial for photosynthesis and respiration in plants.
In most cases it is at the underside of the leaf, as it does not want sunlight to dry it up.
Opening/closing of leaf pores (stoma) has the purpose to control evaporation.
the small openings on the underside of a leaf allow water to come in and replenish the leaf :D

In the underside of the leaf
Ah, the word "underside" brings to mind the gentle image of a leaf, with its vibrant colors on top and delicate veins on the underside. One sentence could be: "As the caterpillar crawled along the underside of the leaf, it marveled at the intricate patterns and shades of green above." Remember, every part of nature has its own beauty, even the underside of things.
These are called "stomata".

Stomata on the underside of the leaf control the passage of gases into and out of the leaf.
