Most xerophytic plants have waxy coating on epidermal cells of leaves to minimize water loss by transpiration. For this reason these plants also have sunken stomato gaurded by trichomes etc.
They live in very hot climates, and so there is a lack of water around.Therefore, they need to retain as much water as possible to help them stay alive.The waxy layer helps reduce water loss from the cacti.
Plaque is the coating that creates white matter.
The fat coating around the dendrites and axons is to insulate them.
waxy coating
yes
Cuticle prevents evaporation .
:O Oh yes they do!
Non metallic coating is not very stable except Graphite coating other coating includes Sulphur coating and organic coating of polymers the temporary coating of wax ,grease and oils also may be used.
Cacti usually have a waxy coating on their leaves to minimise water evaporation. They also have a shallow root system - so they can absorb any rainfall as soon as it hits the ground.
It does melt, if left long enough.The "secret" to deep fried chocolate is the insulation provided by rapid evaporation of water in the breading coating and a VERY short time in the deep fryer.
The coating on aspirin is called an enteric coating.
- coating with another metal - paint coating - plastic coating
no
electrically conducting coating
The upper layer of skin is called cornified layer.This is made up of dead cells thus it forms a hard coating over the skin which protect us from bacterial invation or infection and reduces waterloss by evaporation.
When your body perspires, it is coating your body with sweat. When it is really hot out, the sweat evaporates, cooling your body by removing the sweat.
The coating is to protect the stomach.
