Typically, the waxy layer of a leaf, known as the cuticle, is thinner than the epidermis. The cuticle is a thin, waterproof layer that helps prevent water loss from the leaf, while the epidermis is a thicker layer of cells that provides protection and support to the leaf.
The cuticle is thinner than the epidermis
The thicker cuticle on the upper surface of leaves helps to reduce water loss through transpiration and protect the leaf from environmental stresses like sunlight, wind, and pathogens. This adaptation helps the plant retain moisture and function more efficiently in photosynthesis and gas exchange.
The answer is no, because, on the top of a leaf there is the, cuticle, then the upper epidermis cells underneath, which you can see these, because you can see a sort of jigzaw pattern on the top of the leaf. but on the bottom of a leaf there are tiny, guard cells, a guard cell is a cell that lets in carbon dioxide to the leaf, but only on the bottom of the leaf. if you have ever wondered why a leaf is greener on the top, than the bottom of a leaf, is because, sunlight can easily reach the top of a leaf, this is called photosynthesis, but on the bottom of a leaf, it only gets sunlight from refections from the ground, because the bottom of the leaf does not have any visible contact with the sun.
There is more chlorophyll in the top of the leaf than there is on the bottom
NOPE
A shiny leaf is usually the result of a waxy coating on the leaf's surface. This waxy cuticle helps reduce water loss through evaporation and can also reflect light, giving the leaf a shiny appearance. Some plants naturally have shinier leaves than others due to variations in their wax production.
The pressure against the dam wall increases at the lower levels than nearer the surface. So I expect the foot of the dam wall to be thicker at the bottom than at the top.
The top part of the leaf has more chlorophyll than the bottom.
Because the water pressure at the bottom of the dam is much more than the top.
Look at the Diabolical Ironclad Beetle, and then tell me that insects are thin. If an insect's proportions were to match an average human's height, then it would generally be thicker than a human.
The bottom of a leaf is called the abaxial surface. It is typically lighter in color than the top of the leaf and may have different characteristics, such as more stomata for gas exchange.
