Verified step by step guidance

Understand the context: Multicellular organisms need to replace damaged body cells to maintain tissue integrity and function.

Identify the process: Mitosis is the process by which a cell divides to produce two identical daughter cells, each with the same number of chromosomes as the parent cell.

Explore the role of mitosis: Mitosis is crucial for growth, development, and repair in multicellular organisms, allowing for the replacement of damaged or dead cells.

Differentiate from other processes: Apoptosis is programmed cell death, meiosis is for sexual reproduction, and osmosis is the movement of water across membranes. None of these processes directly replace damaged cells like mitosis does.

Visualize the stages of mitosis: Mitosis consists of several stages—prophase, metaphase, anaphase, and telophase—each contributing to the accurate division and replication of genetic material.
