What are the stages of Mitosis in order and what are the stages of Meiosis in order? Can someone explain all of them please?
Since this is not my area of expertise, I searched Google under the key words "Meiosis mitosis stages" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

Don't just copy the material. Express the ideas in your own words. Although this will take more time and effort, you will learn more.

Certainly! I can explain the stages of Mitosis and Meiosis in order for you.
1. Stages of Mitosis:
Mitosis is a type of cell division that occurs in somatic cells (body cells) and results in the formation of two genetically identical daughter cells. There are four stages of Mitosis:
a. Prophase: In this stage, the chromatin condenses and becomes visible as distinct chromosomes. The nuclear membrane starts to disintegrate, and structures called spindle fibers begin to form.
b. Metaphase: During this stage, the centromeres of the duplicated chromosomes line up along the equatorial plate of the cell. The spindle fibers attach to the centromeres, preparing for the separation of sister chromatids in the next stage.
c. Anaphase: In this stage, the sister chromatids separate and are pulled towards opposite poles of the cell by the contraction of the spindle fibers. Each pole receives an identical set of chromosomes.
d. Telophase: During telophase, the separated chromosomes arrive at the opposite poles of the cell. The nuclear envelope reforms around each set of chromosomes, and the spindle fibers disintegrate. This completes the process of Mitosis.
2. Stages of Meiosis:
Meiosis is a type of cell division that occurs in specialized cells called germ cells and results in the formation of four genetically diverse daughter cells. Meiosis consists of two divisions, Meiosis I and Meiosis II. Each division has four key stages:
a. Prophase I: This is the longest phase of Meiosis. The homologous chromosomes pair up in a process called synapsis, forming structures called tetrads. Crossing over occurs, where segments of genetic material are exchanged between non-sister chromatids, enhancing genetic diversity. The nuclear envelope begins to break down, and the spindle apparatus forms.
b. Metaphase I: During this stage, the homologous pairs of chromosomes line up along the equatorial plate of the cell. Unlike in Mitosis, the homologous chromosomes do not separate at this stage.
c. Anaphase I: In this stage, the homologous chromosomes separate, moving towards opposite poles of the cell. The sister chromatids remain attached, but each pole receives a mixture of maternal and paternal chromosomes.
d. Telophase I and Cytokinesis: The chromosomes arrive at the opposite poles, and the nuclear envelope reforms around each set. Cytokinesis follows, resulting in the division of the cell into two daughter cells.
The Meiosis II division follows a structure similar to Mitosis, where the sister chromatids of each replicated chromosome separate, leading to the formation of a total of four genetically unique daughter cells.
I hope this explanation helps you understand the stages of Mitosis and Meiosis!
