Yes they can as long as an adequate food source is available. This is typically from media with animal serum (ex. bovine). Also an antibiotic is usually added to ensure cell defense. Media will have to be changed routinely.
Not if the petri dish is properly sealed, that is why petri dishes are used in microbiology. However the media used may be contaminated so if growth is found it could be from the media
Skin
You grow an entirely new set of skin cells every seven years.
yes becuase, as they generate they tend to grow faster
All bosy and somatic cells under go mitosis to 1) Grow ( for example your skin cells multiply in order toallow your skin to sketrch when you grow bigger) 2) Repair ( when you get a cut cells will undergo mitosis to repair damaged areas)
they are unipotent
Because your cells start to die. And your cells die your skin gets wrinkly. you have dead skin cells and cells at the elbow.
The skin cells duplicate each other by going through Mitosis.
the skin heals through cells reunion. for example when you have a cut, the cells are being splitted apart. in other for the skin to heal. The cells grow back until they collide with each other. , and then they stop growing. During their process of growing the cut is systematically healing
Skin
Injuries in the brain do not heal because brain cells cannot grow back. On the other hand body cells (skin) do grow back.

the hair on your head will still grow, but the hair you cut off from your head will not. Hair is just dead skin cells, so when it isn't attached to something feeding it more cells, it will not grow
Angora goats grow mohair from cells within their skin.
Do people grow? Are you a multicellular organism? Do you have any cells in your body that can grow and shrink without dividing depending on conditions? FAT and MUSCLE cells do. Do you have any cells in your body that can replicate? Skin and epidermal cells do. Many other cells in the body can undergo some replication during a person's life. A common multicellular microorganism is MOLD. IT CAN GROW AND DIVIDE.
skin cells are flat, because they are skin cells . your skin is flat right ,so that's why skin cells are flat.
