What is mitosis Class 9?

What is mitosis explain?

Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells. The word “mitosis” means “threads,” and it refers to the threadlike appearance of chromosomes as the cell prepares to divide.

What is mitosis * Your answer?

Mitosis is a process of cell duplication, in which one cell divides into two genetically identical daughter cells. In the various stages of mitosis, the cell’s chromosomes are copied and then distributed equally between the two new nuclei of the daughter cells.

What is meiosis Class 9 Ncert?

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.

What is mitosis and explain the phases?

Mitosis Is Divided into Well-Defined Phases. … Today, mitosis is understood to involve five phases, based on the physical state of the chromosomes and spindle. These phases are prophase, prometaphase, metaphase, anaphase, and telophase.

What is mitosis quizlet?

Mitosis. is the process of the division of the nucleus in eukaryotic cells (body cells only). Usually includes four stages: prophase, metaphase, anaphase, and telophase.

What is mitosis Class 9?

Mitosis is a process of cell division. Here the mother cell divides and produces two daughter cells. These daughter cells are identical to each other genetically. In the cell cycle, the division process is known as mitosis, where the DNA in the nucleus of the cell gets split into two equal chromosome sets.

What is meiosis short answer?

Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females. … These four daughter cells only have half the number of chromosomes? of the parent cell – they are haploid.

What is meiosis in biology?

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. … Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome.
