Question

Fill in the blanks
1. Mitosis is a type of cell division takes place in __________ cell
2. Meiosis is a type of cell division takes place in __________ cell
3. In mitosis the chromosome number ___________
4. In meiosis the chromosome number ___________
5. Mitosis occurs at the time of __________ reproduction
6. Meiosis occurs at the time of __________ reproduction

Answer 1

Hint: The process through which the parent cell gets divided into two or more than two, daughter cells is called cell division. The five main phases in the cell division cycle are interphase, prophase, metaphase, anaphase, and telophase. Cytokinesis is the last step in cell division.

Complete answer:
The two types of cell division are mitosis and meiosis.
In mitosis the genetically identical cells are produced. The resultant cells are diploid in nature and this type of cell division takes place throughout the entire life of the living organism that is the somatic cells. The process of mitosis is involved during the asexual reproduction.
On the other hand, in meiosis the genetically unique cells are produced, which are known as germinal cells. The resultant cells are diploid in nature and this type of cell division takes place only at some stages of life in a living organism. The process of meiosis is involved during the sexual reproduction.
Thus, the above blanks would be filled as-
1. Mitosis is a type of cell division that takes place in Somatic cells.
2. Meiosis is a type of cell division that takes place in the germinal cell.
3. In mitosis the chromosome number remains the same.
4. In meiosis the chromosome number is reduced to half.
5. Mitosis occurs at the time of asexual reproduction.
6. Meiosis occurs at the time of Sexual reproduction.

Note:
The German botanist, Hugo Von Mohl first discovered cell division under the microscope. This discovery was made in the year 1835, while working on the green algae. The filming of cell division took place in 1943. For this the scientists Kurt Michel used a phase contrast microscope.
