Hair growth
Lying just beneath the cuticle layer on a leaf, the palisade layer resides very close to the surface. The palisade layer is critical to growth because it is the layer of the leaf that contains the chloroplast.
Contact inhibition, which is a growth mechanism which functions to keep cells growing into a monolayer ( a layer one cell thick).
It functions in appositional bone growth and participates in repairs after an injury.
Epidermis. The layer splits it ad the growth layer in between, like a sandwich.

The topsoil, which is where most root growth occurs, is the most important layer for growing crops.
In the epidermis (the top layer of the skin), there are 5 layers. The bottom layer (The Germinating Layer) has cells that continuously divide by a process know as mitosis. The cells are forced upwards into the next layer (the Prickle Cell Layer), where cells are also constantly dividing. By the time the cells get to the top of that layer, they are dying. The next layer is called the Granular Layer and are slowly forced upwards (although they are dead). Cells go on into the next layer (The Clear Layer) and finally reach the top layer (The Horny Layer) where they are continuously shed. They are then replaced by new ones that have been through the same cycle. The skin is constantly growing new cells and replacing dead ones that are falling off. Hope this helps.
The suggestion to the growth of ozone hole is that it must be stopped. It can cause problems in the near future.
Yes, because they add a new layer of topsoil.
