The waxy transparent layer of leaves prevents water evaporation.
The top layer that people walk on is called the earths crust.
The cuticle.
A waxy layer called the cuticle prevents water loss in leaves.
Leaves have a waxy coating called a cuticle to prevent excess water loss through transpiration. Without this coating they would dry up. The waxy layer blocks the stomata preventing as much water evaporating from them
Because the leaves and branches of the top layer block sunlight from reaching the bottom layer.
The waxy transparent layer of leaves prevents water evaporation.
Leaves have a waxy layer on top of their epidermis layer called the cuticle. This waxy surface protects the leaves from sunburn, dessication (drying out) and reduces attacks by fungi, bacteria, virus particles and insects.
The waxy transparent layer of leaves prevents water evaporation.
The waxy transparent layer of leaves prevents water evaporation.
The waxy transparent layer of leaves prevents water evaporation.
If the bottom layer leaves are small, the would receive lesser sunlight. The top layer leaves are smaller than the bottom layer leaves in size as they can receive more sunlight, thus the bottom layer leaves are larger in size to have a bigger surface area to trap more sunlight. Hope this can help you. '~'
It is called the Epidermis
Cuticle
The top layer that people walk on is called the earths crust.

The cuticle is the waxy waterproof layer on the leaves (it is thicker on the top, but there is also a thin layer underneath the leave), which prevents excessive water loss.
