Somatic cells of the body replicate by mitosis. Examples of somatic cells include fat cells, blood cells, skin cells, or any body cell that is not a sex cell. … Meiosis is the process by which gametes (sex cells) are generated in organisms that reproduce sexually.
What is an example of mitosis?
An example of mitosis is the way the skin cells covering a child’s body all multiply while they are growing. The process in cell division in eukaryotes in which the nucleus divides to produce two new nuclei, each having the same number and type of chromosomes as the original.
What are mitosis and meiosis both examples of?
Mitosis and meiosis are both processes of cell division. Organisms are constantly replenishing their cell supply and creating new cells to replace those that are old or damaged, as well as making cells to be used to create new organisms during sexual reproduction.
Is growing an example of mitosis?
The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue. Some species of algae are capable of growing very quickly.
NGSS Performance Expectations:
|Number of new cells||2 identical cells||4 unique cells|
What are 3 ways mitosis and meiosis?
The differences between mitosis and meiosis
|• Maintenance of chromosome number (diploid)||• Reduction/halving of chromosomes (haploid)|
|• Takes place in somatic cells/growth||• Occurs in reproductive cells/gonads/produces gametes|
|• No crossing over/no variations||• Crossing over takes place/variation occurs|
Which of the following is an example of meiosis?
An example of meiosis is when a chromosome reduces from a double cell to a single cell.
How do you explain mitosis to a child?
The process of cell division, during which one cell gives rise to two identical daughter cells, is called mitosis. The process of mitosis is essential to life: it provides new cells for growth and replaces old and dying cells.
Are daughter cells identical in meiosis?
Like mitosis, meiosis is a form of eukaryotic cell division. … Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.
How is meiosis 1 and meiosis 2 different?
In meiosis I, homologous chromosomes separate, while in meiosis II, sister chromatids separate. Meiosis II produces 4 haploid daughter cells, whereas meiosis I produces 2 diploid daughter cells. Genetic recombination (crossing over) only occurs in meiosis I.
What are 4 similarities between mitosis and meiosis?
The similarities between mitosis and meiosis are as follows:
- Mitosis and meiosis take place in the cell nuclei.
- Both involve cell division.
- Both the processes occur in the M-phase of the cell cycle.
- In both cycles, the stages are common – metaphase, anaphase, telophase and prophase.
- Synthesis of DNA occurs in both.
Is asexual mitosis or meiosis?
Meiosis does not occur during asexual reproduction. Meiosis is the process of producing gametes (eggs and sperm). Mitosis, on the other hand, is simply the process of cell division. This is the process that animals are going through during regeneration.
Where does mitosis occur in the skin?
Mitosis occurs in the deepest layer of the epidermis, which is called the stratum basale.
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 is different between mitosis and meiosis?
Cells divide and reproduce in two ways, mitosis and meiosis. 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.
What are the 2 main functions of meiosis?
What Are Two Main Functions Of Meiosis?
- Production of gametes. Meiosis in humans causes the decrease or reduction of the number of chromosomes in normal cells.
- Induces genetic variation by the process of recombination.
