AnswersDriveThe chemical division process called mitosis is split into the following 6 steps, such that: interphase, prophase, metaphase, anaphase, telophase, cytokinasis. The firts step of mitosis is characterized by the presence of one cell, but in the end of process there exists two identical cells.
What are 4 phases of mitosis in order?
But first, here are the stages of mitosis:
- prophase.
- prometaphase.
- metaphase.
- anaphase.
- telophase.
Which cell is in the first phase of mitosis?
Prophase is the first stage in mitosis, occurring after the conclusion of the G2 portion of interphase. During prophase, the parent cell chromosomes — which were duplicated during S phase — condense and become thousands of times more compact than they were during interphase.
1
What is the process of mitosis?
These stages are prophase, prometaphase, metaphase, anaphase, and telophase. During mitosis, the chromosomes, which have already duplicated, condense and attach to spindle fibers that pull one copy of each chromosome to opposite sides of the cell.
2
What are the steps of meiosis in order?
Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.
3
What are the stages of mitosis and what happens in each?
Mitosis and Cytokinesis. During mitosis, when the nucleus divides, the two chromatids that make up each chromosome separate from each other and move to opposite poles of the cell. Mitosis actually occurs in four phases. The phases are called prophase, metaphase, anaphase, and telophase.

What divides in mitosis?
The mitosis division process has several steps or phases of the cell cycle—interphase, prophase, prometaphase, metaphase, anaphase, telophase, and cytokinesis—to successfully make the new diploid cells. When a cell divides during mitosis, some organelles are divided between the two daughter cells.
5
What is the final phase of mitosis?
Telophase is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. Telophase begins once the replicated, paired chromosomes have been separated and pulled to opposite sides, or poles, of the cell.

What are the eight stages of meiosis?
8 Stages of Meiosis
- Prophase I. The chromosomes condense, and the nuclear envelope breaks down.
- Metaphase I. Pairs of homologous chromosomes move to the equator of the cell.
- Anaphase I. Homologous chrmosomes move to the oppisite poles of the cell.
- Telophase I and Cytokinesis.
- Prophase II.
- Metaphase II.
- Anaphase II.
- Telophase II and Cytokinesis.
7
What is the process of spermatogenesis?
The seminiferous tubules of the testes are the starting point for the process, where spermatogonial stem cells adjacent to the inner tubule wall divide in a centripetal direction—beginning at the walls and proceeding into the innermost part, or lumen—to produce immature sperm. Maturation occurs in the epididymis.
8
What are the stages of meiosis?
Therefore, meiosis includes the stages of meiosis I (prophase I, metaphase I, anaphase I, telophase I) and meiosis II (prophase II, metaphase II, anaphase II, telophase II).
9
What is mitosis and what does it do?
The main functions of mitosis are growth and repair. Some cells once fully formed do not undergo cell division, such as nerve cells and muscle cells. Since you can never re-grow or repair these types of cells once they are mature, you must take care of the ones you have.
10
What happens in the prophase of mitosis?
Concept 5: Prophase. Chromosomes become visible, the nucleolus disappears, the mitotic spindle forms, and the nuclear envelope disappears. Each duplicated chromosome is seen as a pair of sister chromatids joined by the duplicated but unseparated centromere.
11
What are the five main stages of mitosis?
5 Stages of Mitosis
- Interphase. During interphase, the cell is preparing itself for division.
- Prophase. In the phase to follow, called prophase, the duplicated chromosomes from the previous phase condense, meaning they become compacted and more tightly wound.
- Metaphase.
- Anaphase.
- Telophase.
- Cytokinesis.
12
Which is not part of mitosis?
Interphase is often included in discussions of mitosis, but interphase is technically not part of mitosis, but rather encompasses stages G1, S, and G2 of the cell cycle. The cell is engaged in metabolic activity and performing its prepare for mitosis (the next four phases that lead up to and include nuclear division).
13
How many cells are produced by mitosis?
The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell. Meiosis has both similarities to and differences from mitosis, which is a cell division process in which a parent cell produces two identical daughter cells.
14
What are the types of cells that undergo mitosis?
What types of cells and organisms undergo mitosis and meiosis. Mitiosis undergo cells and organisms that can reproduce asexually and create indentical copies of their DNA. Meiosis uses organisms that rely on sexual reproduction however the process of mitosis is still needed for growth.
15
What are the stages of mitosis in order?
These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts in anaphase or telophase. Stages of mitosis: prophase, metaphase, anaphase, telophase. Cytokinesis typically overlaps with anaphase and/or telophase.
16
What is the first phase of mitosis?
Prophase is the first stage in mitosis, occurring after the conclusion of the G2 portion of interphase. During prophase, the parent cell chromosomes — which were duplicated during S phase — condense and become thousands of times more compact than they were during interphase.
17
What happens during the process of mitosis?
What happens during mitosis? During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Mitosis itself consists of five active steps, or phases: prophase, prometaphase, metaphase, anaphase, and telophase.
18
What are the three major stages of interphase?
There three stages in interphase occur in a particular order as part of the cell cycle; cells spend a majority of this cycle in interphase.
- The Purpose of Interphase. While prokaryotic cells, like bacteria, replicate through binary fission, eukaryotic cells divide through mitosis or meiosis.
- G1 Stage.
- S Phase.
- G2 Stage.
19
How mitosis is important for your body?
It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged. In mitosis a cell divides to form two identical daughter cells.
20
What is the process that follows mitosis?
Mitosis is the process in which a eukaryotic cell (cell containing a nucleus) separates its already duplicated chromosomes (copied during the S phase) into two sets of chromosomes so there will be two identical nuclei. It is generally followed by cytokinesis which divides the cytoplasm and cell membrane.
