The basal keratinocytes which comprises the stratum basale/germinativum of the skin are mitotically active.

Complex organisms use mitotic cell division to grow and to repair damage, and to replace dead or dying cells.
It is important because it gives us fresh skin cells. It keeps our body protected. We have new skin that will heal faster.

Your body is constantly replace the dead cells with new ones. So that the tissue in your cells can work actively...
Actually it is not that difficult for the skin to repair itself when only the epidermis is damaged. It's when the dermis is injured that the process becomes more complicated. It is difficult to only injure the epidermis, but it happens. The epidermis is avascular, meaning it does not contain blood vessels and therefore does not bleed. Epidermal wounds usually involve only minor damage to the superficial epidermal cells although the center of the wound could extend slightly into the dermis. These types of wounds include minor skin abrasions, where a portion of the skin has been scraped away, and minor burns. In response to an epidermal injury, basal cells from the deepest layer of the epidermis --the stratum basale-- surrounding the wound break off from the basement membrane (epidermal-dermal junction). The cells then enlarge and migrate across the wound. The cells continue to migrate until they meet cells migrating from the opposite side of the wound. Migration of the cells stops when each cell is finally in contact with other epidermal cells on all sides. As the basal epidermal cells migrate, a hormone called epidermal growth factor stimulates basal cells to divide and replace those who have left to fill in the wound. The relocated basal epidermis cells divide to build new strata, thus thickening the new epidermis. Viola, the skin is repaired!

Cork cambium is used for secondary growth.Cork cambium produces new dermal tissues that replace the epidermal tissues from protoderm. Cork cambium is consisted of cork cambium and cork.
All multicellular plants and animals, as well as fungi and protists, use mitotic cell division to develop from single cell organisms into organisms containing billions of cells. Mitosis continues in full-grown organisms replacing dying or repairing damaged cells. Throughout the human body, an estimated 25 million mitotic cell divisions occur every second in order to replace cells that have completed their normal life cycles. Some multicellular organisms rely on mitosis for asexual reproduction, and it is the only reproduction method used by many single-celled organisms.
Everything will still work. However gnome applications do not interact with the desktop environment of KDE as well as they would with gnome. The differences will be mainly superficial. You can always remove the gnome applications later and replace them with kde ones if you want.
There are several layers of skin, listed here from deep to superficial: Dermis, {stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum}. Those inside the {} are parts of the epidermis. The stratum basale has stem cells that undergo mitosis, causing them to give rise to keratinocytes that migrate toward the skin surface and replace dead or lost epidermal cells. The next layer (stratum spinosum) also has capability of mitosis, but only in the deepest area. As the cells are pushed further toward the surface, they lose the ability to divide. Basically, the cells continue to reproduce at the basement layer (stratum basale), and those new cells force the older cells toward the surface, forming the layers of the epidermis. ;-)
Replace will replace one instance of what you want to replace. Replace All will replace all instances of what you want to replace.
