The mitotic index is calculated by counting the number of cells undergoing mitosis and dividing it by the total number of cells counted in a particular area of interest, then multiplying by 100 to get a percentage. This provides a measure of the proportion of actively dividing cells in a tissue sample, which can be important for understanding cell proliferation and growth rates.

How do you calculate a mitotic index?
To calculate the mitotic index, you count the number of cells undergoing mitosis in a given sample and divide this number by the total number of cells in the sample. The result is usually expressed as a percentage. Mitotic index is commonly used to assess the rate of cell division in tissues, especially in cancer research.
What is the mitotic index for the onion root tip?
The mitotic index for the onion root tip is typically around 18-20%, meaning that around 18-20% of cells in the onion root tip are actively undergoing mitosis at any given time. This high mitotic index is due to the rapid growth and development of the root tip.
Which type of tissue would have a higher mitotic index normal tissue or cancerous tissue?
Cancer cells have higher mitotic index because they have a mutation in the DNA so they reproduce uncontrollably and therefore divide faster which means they have a higher mitotic index. ex. In a normal lung tissue, % of cells dividing is 5% while in a cancerous lung the % of cells divding is 25 %

Why does skin have the highest mitotic index?
Skin has a high mitotic index because the skin cells are constantly renewing and replacing themselves due to wear and tear. The outermost layer of skin, the epidermis, contains rapidly dividing cells that continuously produce new skin cells to maintain and repair the skin barrier. This rapid turnover of cells is important for skin regeneration and wound healing.

Which has highest mitotic index muscle skin kidney or lung?
Skin because it has to be continuously replaced.
Why root tips are placed in 10 percent hydrochloric acid mitotic index?
Root tips are placed in 10% hydrochloric acid to break down the cell walls and release the cells for analysis. The mitotic index is calculated as the ratio of cells in mitosis to the total number of cells examined, providing information on the rate of cell division in the root tip. This method helps to determine the growth activity and health of the plant.
What is the mitotic index for the onion root tip?
The mitotic index for the onion root tip is typically around 18-20%, meaning that around 18-20% of cells in the onion root tip are actively undergoing mitosis at any given time. This high mitotic index is due to the rapid growth and development of the root tip.
Why would the mitotic index be relevant to a diagnosis of breast cancer?
Because cancer is uncontrolled mitosis of cells; thus if the mitotic index of the breast cells in question is outside the normal range (above it, generally), then this would suggest increased rate of cell proliferation which could indicate cancer.
Which type of tissue would have a higher mitotic index normal tissue or cancerous tissue?
Cancer cells have higher mitotic index because they have a mutation in the DNA so they reproduce uncontrollably and therefore divide faster which means they have a higher mitotic index. ex. In a normal lung tissue, % of cells dividing is 5% while in a cancerous lung the % of cells divding is 25 %
