Mitosis occurs in only somatic cells/both somatic and germ cells.

Text Solution

AI Generated Solution

**Step-by-Step Solution:** 1. **Understanding Mitosis**: Mitosis is a type of cell division that results in two genetically identical daughter cells from a single parent cell. This process is essential for growth, repair, and asexual reproduction in organisms. 2. **Types of Cells**: There are two main types of cells in multicellular organisms: somatic cells and germ cells. - **Somatic Cells**: These are non-reproductive cells that make up most of the body tissues and organs. - **Germ Cells**: These are reproductive cells (sperm and eggs) that are involved in sexual reproduction. ...

Meiosis takes place in both somatic cells and germ cells.

In eukaryotes, the process of division of a somatic parent cell into two daughter cells is known as mitosis. During the M or mitosis phase of a cell cycle, the chromosomes present in the nucleus are separated into two identical sets, which eventually form two daughter nuclei. This is followed by cytokinesis. Onion root tips are most commonly used to observe the different stages of mitosis in the laboratory. Each onion cell contains a total of eight chromosomes. DNA specific stains are used to visualise these chromosomes in different phases of mitosis. Mention are difference between mitosis occurring in onion root tip cell and human cheek cells.
