because the skin is constantly needing repair
Liver cells divide about once a year, and neurons (nerve cells) never divide once we are born (and when they are mature).
As far as I know, liver cells usually only undergo mitosis if the liver is damaged. You should check a few other sources though.
Labile cells are constantly dividing and regenerating, such as skin epithelial cells. Permanent cells do not normally regenerate, such as neurons. Stable cells have a low rate of division but can regenerate under certain conditions, such as liver cells.
liver cells
Yes, a liver cell is a type of somatic cell. Somatic cells are any cell in the body that is not a sperm or egg cell. Liver cells are an example of somatic cells because they make up the majority of the cells in the liver and are responsible for the organ's function.
Yes, liver cells are capable of division. This process, known as mitosis, allows liver cells to regenerate and repair damage. However, the rate of cell division in the liver is lower compared to other tissues like skin or intestines.
No, different cell types divide at different rates. For example, skin cells divide rapidly, while heart cells divide very slowly or not at all. The rate of cell division is determined by factors such as their function and location in the body.
In neurons. Also liver cells typically don't divide, but can start dividing if a serious damage is done to the liver.
No, a liver cell is a eukaryotic cell. Eukaryotic cells, like liver cells, have a well-defined nucleus that contains the cell's genetic material and are more complex than prokaryotic cells, which lack a nucleus.
During mitosis, liver cells undergo cell division to produce two identical daughter cells. This process allows the liver to regenerate and maintain its functionality. Liver cells replicate their DNA, distribute their chromosomes equally, and then divide to ensure the continual renewal of liver tissue.
All cells will stop dividing when you die. When you're born, cells slow down the dividing, but don't completely stop.
Both plant and animal cells use mitosis to form two daughter cells. They are usually called soma (body) cells but there are some exceptions: nerve cells and liver cells. The liver cells can divide in the time of need.
