Mitosis is used for several purposes
1. Growth. the embryo increases in size due to mitosis. Enlargement of the embryo, young child and growth during puberty is due in part to increasing the number of cells.
2. Repair. If you cut yourself, or an incision is made during surgery, the hole is closed by cells dividing to close the space created by the wound.
3. Replacement. Some cells wear out rapidly (blood - 90-120 days; skin - 2 weeks; intestine 2.5 days) these old and worn out cells need to be replaced on a constant basis
4. Reproduction - protists that undergo mitosis have produced two identical cells and thus have reproduced
5. Cancer - unfortunately cancer is mitosis of cells that we don't want to be undergoing mitosis.
Meiosis
is used to produce the sperm and the egg each of which have half the number of chromosomes as the starting cell. This is so that when a sperm fertilizes an egg the total number of chromosomes is equal to that in any other cell
What else can I help you with?
How are mitosis and meiosis simlair?
Meiosis and Mitosis are both the division of something. Meiosis is the division of chromosomes and Mitosis is the division of cells. They both occur in the cell cycle. Meiosis creates 4 daughter cells and Mitosis creates two complete cells.
What are 2 parts of meiosis that are similar to mitosis?
The part of meiosis that is similar to mitosis is inter-phase.
When does replication happen during mitosis or meiosis?
Replication occurs during the S phase of the cell cycle before both mitosis and meiosis. In mitosis, the replicated DNA is separated into two identical daughter cells. In meiosis, the replicated DNA is separated into four haploid daughter cells with genetic variation.
What type of cell division Mitosis or meiosis is important in genetic study?
Both
Do human use mitosis or miosis?
Humans use both- mitosis to grow, meiosis to form sex cells for reproduction.
Is metaphase a phase in mitosis or meiosis?
Metaphase is a phase in both mitosis and meiosis.
How are mitosis and meiosis simlair?
Meiosis and Mitosis are both the division of something. Meiosis is the division of chromosomes and Mitosis is the division of cells. They both occur in the cell cycle. Meiosis creates 4 daughter cells and Mitosis creates two complete cells.
Is DNA replication involved in mitosis or meiosis?
DNA replication is involved in both mitosis and meiosis.
From which type of cell do both mitosis and meiosis start?
Both mitosis and meiosis start from a type of cell called a diploid cell.
Occurs in both plants and animals mitosis or meiosis?
Mitosis. Meiosis is only concerned in sex cells.
Is cell division in the process of mitosis or meiosis?
Cell division occurs in both the processes of mitosis and meiosis.
How is mitosis similar to mitosis?
Both meiosis and mitosis are forms of cell reproduction.They both have a prophase and an anaphase.Both are forms of cell reproduction/Both are forms of nuclear division. Meiosis occurs in generative cells and mitosis in somatic cells.
Are homologous chromosomes present in both mitosis and meiosis?
Yes, homologous chromosomes are present in both mitosis and meiosis. In mitosis, homologous chromosomes do not pair up, while in meiosis, homologous chromosomes pair up during prophase I.
What phases are found in both meiosis and mitosis?
The phases found in both meiosis and mitosis are prophase, metaphase, anaphase, and telophase. In meiosis, there are two rounds of division (meiosis I and meiosis II), while mitosis only involves one round of division.
How are meiosis and mitosis similar?
they both have a prophase and an anaphase.
Is crossing over a key process that occurs during both mitosis and meiosis?
Yes, crossing over is a key process that occurs during both mitosis and meiosis.
Is DNA replicated during mitosis or meiosis?
DNA is replicated during the S phase of the cell cycle before both mitosis and meiosis.
