Verified step by step guidance

Understand the context of cell division: Cell division is a process where a parent cell divides into two or more daughter cells. It is crucial for growth, development, and repair in multicellular organisms.

Identify the types of cells mentioned: Skin cells, cancer cells, cells from an embryo, and nerve cells. Each type has different characteristics and roles in the body.

Consider the division characteristics of each cell type: Skin cells frequently divide to replace dead or damaged cells. Cancer cells divide uncontrollably, which is a hallmark of cancer. Embryonic cells divide rapidly during development.

Focus on nerve cells: Nerve cells, or neurons, are specialized cells that typically do not divide after they have fully matured. They are involved in transmitting signals throughout the nervous system.

Conclude why nerve cells are unlikely to divide: Unlike the other cell types mentioned, mature nerve cells generally remain in a non-dividing state, known as the G0 phase of the cell cycle, making them unlikely to divide.
