Verified step by step guidance

Understand the basic concept of cell division: Cell division is a fundamental process in biology where a single parent cell divides to form two or more daughter cells. This is essential for growth, development, and repair in organisms.

Identify the types of cell division: There are two main types of cell division - mitosis and meiosis. Mitosis results in two identical daughter cells and is used for growth and repair, while meiosis results in four genetically diverse daughter cells and is used in sexual reproduction.

Evaluate the statement about maturity: Cell division is not unnecessary once an organism reaches maturity. Even mature organisms require cell division for tissue repair and maintenance.

Consider the fusion of sex cells: The fusion of sex cells is not cell division; it is fertilization, which is a separate process where two gametes (sperm and egg) combine to form a zygote.

Clarify the stages of cell division: Mitosis and meiosis are distinct processes. Mitosis involves stages like prophase, metaphase, anaphase, and telophase, while meiosis includes two rounds of division (meiosis I and II) and is specific to the formation of gametes.
