Skin cells because they need to get replaced the most often. Which type of tissue would have a higher mitotic index, normal tissue or cancerous tissue? Cancerous tissue would have a higher mitotic index because the cells are constantly dividing.
What human cells perform the highest rate of mitosis?
For example bone marrow which is responsible for blood cell production is an area in the body where rapid mitosis occurs. Skin cells, hair follicles and the cells lining our intestines (epithelial cells) all have high rates of mitosis as these tissues constantly need to be replaced.
What has a higher mitotic index normal cells or cancerous cells?
An elevated mitotic index indicates more cells are dividing. In cancer cells, the mitotic index may be elevated compared to normal growth of tissues or cellular repair of the site of an injury.
What type of cells go through mitosis the most often?
In contrast to prokaryotic cells, eukaryotic cells may divide via either mitosis or meiosis. Of these two processes, mitosis is more common.
Which human cells divide the fastest?
The fastest-dividing human cells can complete a cell cycle in about 24 hours (G1: 9h, S: 10h, G2: 4h, M: 30 min).

What type of tissue would have a higher mitotic index?
Which type of tissue would have a higher mitotic index, normal tissue or cancerous tissue? Cancerous tissue would have a higher mitotic index because the cells are constantly dividing.
What is the mitotic index used for?
The mitotic index (percentage of cells in mitosis at any time) provides a measure of the capacity of cells to divide and of the rate of cell division. It is used to identify the sites of growth within a tissue and to determine which cell types are dividing.
What is a mitotic index quizlet?
the mitotic index is the number of cells going through mitosis.
What is mitotic index a level biology?
mitotic index = number of cells with visible chromosomes ÷ total number of cells.
Why is the mitotic index less than 100?
Mitotic index decreases with increasing distance from root tip. That means gradual decrease in cell division as it moves from the zone of cell division to the zone of cell elongation.
What are the mitotic figures?
A mitotic figure is a cell that is in the process of dividing to create two new cells. … Mitotic figures are easy to see because the genetic material inside the nucleus changes colour and shape before the cell divides.
How often do cells go through mitosis?
Human somatic cells go through the 6 phases of mitosis in 1/2 to 1 1/2 hours, depending on the kind of tissue being duplicated. Some human somatic cells are frequently replaced by new ones and other cells are rarely duplicated.
What kind of cells does mitosis produce?
Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.
Does mitosis make haploid or diploid cells?
Meiosis produces 4 haploid cells. Mitosis produces 2 diploid cells. The old name for meiosis was reduction/ division. Meiosis I reduces the ploidy level from 2n to n (reduction) while Meiosis II divides the remaining set of chromosomes in a mitosis-like process (division).
