If a leaf has a thick waxy cuticle then it reduces water loss due to the lipids and fats being hydrophobic to water, this prevents evaporation and thus slows transpiration. Also the shiny surface reflects some sunlight which can reduce heat at the surface of the water reducing evaporation further.
It restricts cuticular transpiration
Let's think about this for a minute and you'll figure it out. Do they need to be protected from extreme temperature? Do they need something to keep water from evaporating too quickly and drying them out? Yes, so they'd need a thick protective cuticle.
cuticle coating on leaves and thick epidermal cell walls
This is a reasoned guess but I would say arid regions such as the desert to prevent water loss.
yes conifers have a cuticle.
Thick cuticle limits transpiration.
The desert; a thick cuticle will prevent/reduce water loss
No.
For protection against fauna
Arthropods, more specifically, crustaceans, have a thick, tough cuticle and two pair of antennae. The cuticle acts as an exoskeleton and two pair of antennae to help them find food and keep them safe.
cuticle it on the leaf for the bugs to eat to keep out posion
structural adaptations
It restricts cuticular transpiration
The cuticle. It's usually not that thick, but with succulents, it's really thick and waxy to hold in as much water as possible.

cuticle is the thick layer outside the leaf to prevent loss of water.
