What is the official name for cell division?
There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells.
What is the name of cell division in prokaryotes?
The usual method of prokaryote cell division is termed binary fission. The prokaryotic chromosome is a single DNA molecule that first replicates, then attaches each copy to a different part of the cell membrane.
Is mitotic and mitosis the same?
In the cell cycle, the cell's DNA is replicated in interphase, the phase that precedes mitosis….Mitosis Versus Meiosis: The Similarities and Differences.
| Mitosis | Meiosis | |
|---|---|---|
| Ploidy | Diploid daughter cells | Haploid daughter cells |
| Genetics | Daughter cells are genetically identical | Daughter cells are genetically different |

How does cell division differ in prokaryotes and eukaryotes?
The main difference between prokaryotic and eukaryotic cell division is that the prokaryotic cell division occurs through binary fission whereas the eukaryotic cell division occurs either through mitosis or meiosis. Furthermore, prokaryotic cells lack a nucleus while eukaryotic cells have a nucleus.
Is mitosis eukaryotic or prokaryotic?
eukaryotes While both binary fission and mitosis are types of cell division that duplicate cells, fission primarily occurs in prokaryotes (bacteria), while mitosis occurs in eukaryotes (e.g., plant and animal cells).
Why do eukaryotic cells divide?
Cell division in eukaryotic organisms is necessary for development, growth, and repair of the organism. Just as in binary fission, eukaryotic cell division ensures that each resulting daughter cell receives a complete copy of the organism's entire genome.
What is meiotic division?
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.
Is meiotic and meiosis same?
Meiosis consists of meiosis I and meiosis II. In meiosis I, homologous chromosomes are separated into different nuclei. This is the reduction division; chromosome number is divided in half. Meiosis II is very similar to mitosis; chromatids are separated into separate nuclei.
Is cell division the same in prokaryotes and eukaryotes?
The main difference between prokaryotic and eukaryotic cell division is that the prokaryotic cell division occurs through binary fission whereas the eukaryotic cell division occurs either through mitosis or meiosis. Furthermore, prokaryotic cells lack a nucleus while eukaryotic cells have a nucleus.
Why does mitosis occur in eukaryotes?
Organisms which reproduce asexually cannot undergo meiosis, whereas all eukaryotic organisms undergo mitosis. Mitosis and meiosis are similar in that both can only occur in eukaryotic cells. This is because prokaryotic cells do not contain a nucleus within which to begin the processes of mitosis and meiosis.
What happens in the eukaryotic cell division?
In eukaryotes, the cell cycle consists of four discrete phases: G1, S, G2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides. The other two phases — G1 and G2, the so-called gap phases — are less dramatic but equally important.
Where does the cell division occur in the eukaryotic cell?
Cell division occurs at the end of an eukaryotic cell's cell cycle. Eukaryotic cell division occurs in two major steps: The first step is mitosis, a multi-phase process in which the nucleus of the cell divides. During mitosis, the nuclear membrane breaks down and later reforms.
What is another name for meiosis?
meiosis, also called reduction division, division of a germ cell involving two fissions of the nucleus and giving rise to four gametes, or sex cells, each possessing half the number of chromosomes of the original cell.
What is Reductional division?
Reduction division: The first cell division in meiosis, the process by which germ cells are formed. In reduction division, the chromosome number is reduced from diploid (46 chromosomes) to haploid (23 chromosomes). Also known as first meiotic division and first meiosis.
Why is mitosis called equational division?
Explanation: Mitosis is called equational division because each of the two daughter cells formed, get the same number of chromosomes as the parent.
Is mitotic and mitosis same?

Is mitosis prokaryotic or eukaryotic?
Mitosis is the eukaryotic answer to binary fission in the single-celled prokaryotes, which is similar on the surface but simpler at the level of details. Mitosis in humans is fundamentally the same as it is in all eukaryotes.
How is cell division different in prokaryotes and eukaryotes?
The main difference between prokaryotic and eukaryotic cell division is that the prokaryotic cell division occurs through binary fission whereas the eukaryotic cell division occurs either through mitosis or meiosis. Furthermore, prokaryotic cells lack a nucleus while eukaryotic cells have a nucleus.
Where does mitosis occur in eukaryotic cells?
Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.
What are the two divisions of eukaryotic cells?
In eukaryotes, there are two distinct types of cell division; a vegetative division, whereby each daughter cell is genetically identical to the parent cell (mitosis), and a reproductive cell division, whereby the number of chromosomes in the daughter cells is reduced by half to produce haploid gametes (meiosis).
What is another name of mitosis?
cell division Another name for cell division is "mitosis." If you study biology, you'll learn about cell division, when a cell divides into two smaller "daughter cells." During cell division, all the tiny elements of the cell also divide — including the cell's chromosomes, nucleus, and mitochondria.
What is meiotic cell division?
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.
What is Reductional and equational division?
The key difference between equational division and reduction division is that equational division refers to meiosis II, during which the chromosomal number remains equal as haploid. In contrast, reduction division refers to meiosis I, during which the chromosome number reduces to half from the diploid state.
What is equatorial division?
equatorial division The division of each chromosome during the metaphase of mitosis or meiosis into two equal longitudinal halves which are then incorporated into separate daughter nuclei. A Dictionary of Plant Sciences.
Why is meiosis called as Reductional division?
Meiosis is sometimes called "reduction division" because it reduces the number of chromosomes to half the normal number so that, when fusion of sperm and egg occurs, baby will have the correct number.
What is meiotic and meiosis division?
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.

During cell division, all the tiny elements of the cell also divide — including the cell's chromosomes, nucleus, and mitochondria.
How do prokaryotic and eukaryotic cells divide?
Most prokaryotic cells divide by the process of binary fission. In eukaryotes, cell division occurs in two major steps: mitosis and cytokinesis.
