Describe the growth and repair cycle of the skin?
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 :)
Why does your skin renew itself?
The inner layer is constantly growing new cells which are pushed outward, where they desiccate and die. Each cell (as its dieing) is designed to attach itself to the cells next to it. If all goes well then you have a thin layer of dead, dry cells exposed to the outside world which slowly flake off. If the the cells are too well attached then you get flakes that are visible ... like dandruff or psoriasis.
Where do New cells of the epidermis originate?
They originate in the deepest layer of epidermis, called stratum basale. The columnar cells of this deep layer are constantly dividing to produce new cells that move outward to undergo metamorphosis at different levels.
What is the cases represented as the phenomenon of contact inhibition?
Contact inhibition helps keep cells growing in a layer that is the width of one cell. Cancer cells lose this property when they form.
Why does bark grow on trees?
Trees have bark to protect a layer that is underneath it, the cambium. This is the only part of the tree that has living, growing cells.
What is the flaking of the outer layer of dead skin cells on the scalp?
That is called tissue.

The portion of the epidermis from which cells are constantly sloughed off is the?
basal layer
How does a sunburn come off?
The skin is a living thing, the outer layer is constantly dieing and flaking off, while a new layer is growing right underneath. As more and more of the "old" tanned/sunburned layer gets replaced with new skin, the tan/burn will fade. Unless you stay in the sun of course, in which case the new skin will tan/burn as it appears too.

Why are youre skin cells continuously undergoing mitosis?
Bacteria is constantly forming on the outer layer of your skin. It is looking for a way to invade your body. Your body reacts by simply throwing away the outer layer of your skin. It does that a cell at a time, but it does it constantly. Those cells must be replaced. To do that, the cells underneath must constantly reproduce and create new skin cells.

What do you normally call epidermis?
The epidermis is the outer layer of skin, this goes for almost all animals and plants. In mammals the epidermis consists of four to five separate layers, the top layer is made up of cornified cells, which form the primary protective layer. This layer is constantly renewed by releasing dead cells and advancing new cells. The bottom layer creates new cells which then start their journey to the top layer.
The protective layer of cells that covers the actively growing tip of a root?
root cap
What layer of the epidermal region has scalelike cells full of keratin that constantly flake off?
The outer layer of the epidermis is full of scale like that frequently flake off. These cells are pushed to the surface as they begin to die.
How does the long narrow shape of cells in the palisade layer adapt the cells to their major function?
The long narrow shape of cells in the palisade layer adapt the cells to their major by shedding whatever isn't needed and growing what is needed to be able to function in their area.
