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 another term for meiosis?
nounformation of cells by dividing. amitosis. cellular division. meiosis. mitosis.
What is the term for mitosis?
In biology, mitosis refers to the cellular process where a single cell divides resulting in two identical cells. … Now, the term mitosis is used interchangeably with cell division.
What is 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. … During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.
What is a antonym for meiosis?

What is the root word of meiosis?
As with so many scientific terms, the word meiosis comes from the Greek, in this case meíōsis, which means “a lessening.” This idea makes sense, as meiosis creates cells with half the chromosomes than the original.
What happens anaphase?
During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes. The chromosomes are separated by a structure called the mitotic spindle. … The separated chromosomes are then pulled by the spindle to opposite poles of the cell.
What is the product of meiosis?
Cytokinesis splits the chromosome sets into new cells, forming the final products of meiosis: four haploid cells in which each chromosome has just one chromatid. In humans, the products of meiosis are sperm or egg cells.
Is one division mitosis or meiosis?
Mitosis involves one cell division, whereas meiosis involves two cell divisions.
Is mitosis a cell division?
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 is meiosis Class 9?
Meiosis is the process in which a single cell divides twice to form four haploid daughter cells. These cells are the gametes – sperms in males and egg in females.
