What is the major difference in mitosis and meiosis?
Table of Contents
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 five differences between mitosis and meiosis Class 11?
Cells multiply and reproduce in two ways-mitosis and meiosis….Complete answer:
| Mitosis | Meiosis |
|---|---|
| Mode of reproduction- Asexual | Sexual |
| Cytokinesis occurs in telophase | Cytokinesis occurs in Telophase I and II |
| No recombination. | Recombination and crossing over take place between homologous chromosomes. |
What is the differences between mitosis and mitosis?
The differences between mitosis and meiosis
| Mitosis | Meiosis |
|---|---|
| • Takes place in somatic cells/growth | • Occurs in reproductive cells/gonads/produces gametes |
| • No crossing over/no variations | • Crossing over takes place/variation occurs |
| • Results into 2 daughter cells | • Results into 4 daughter cells |
What are the differences between mitosis and meiosis Class 9?
Mitosis results in two nuclei that are identical to the original nucleus. Meiosis, on the other hand, results in four nuclei that each has ½ the chromosomes of the original cell. In animals, meiosis only occurs in the cells that give rise to the sex cells (gametes), i.e., the egg and the sperm.
What are the similarities between mitosis and meiosis?
Similarities: Both mitosis and meiosis involve nuclear division that results in the formation of new cells. DNA should be replicated before both meiosis and mitosis. Both have the same stages (prophase, metaphase, anaphase, and telophase). But there occurs some specific events like crossing over (recombination) in meiosis.
What are the steps of mitosis?
Interphase. Before a dividing cell enters mitosis,it undergoes a period of growth called interphase.
What exactly happens during meiosis?
What exactly happens during meiosis? In meiosis, the chromosome or chromosomes duplicate (during interphase) and homologous chromosomes exchange genetic information ( chromosomal crossover) during the first division, called meiosis I. The daughter cells divide again in meiosis II, splitting up sister chromatids to form haploid gametes.
What are five stages of mitosis?
– The chromosomes start to condense (making them easier to pull apart later on). – The mitotic spindle begins to form. – The nucleolus (or nucleoli, plural), a part of the nucleus where ribosomes are made, disappears.
