Cells that are no longer needed die in a process called Blank______.Multiple choice question.meiosisgastrulationapoptosismitosis

Step 1: Break Down the Problem

Identify the correct term for the process by which cells that are no longer needed die.

Step 2: Relevant Concepts

The provided options are:

1. Meiosis
2. Gastrulation
3. Apoptosis
4. Mitosis

Definitions:

• Meiosis: A type of cell division that reduces the chromosome number by half, resulting in the production of gametes (sperm and eggs).
• Gastrulation: An early phase in embryonic development that involves the reorganization of the cells in the embryo.
• Apoptosis: The process of programmed cell death that occurs in multicellular organisms.
• Mitosis: A type of cell division that results in two daughter cells, genetically identical to the parent cell.

Step 3: Analysis and Detail

Among the options, apoptosis is specifically associated with the controlled and regulated process of cell death, making it the correct term for cells that are no longer needed.

Step 4: Verify and Summarize

The definition and role of apoptosis confirm it as the process by which unnecessary or damaged cells undergo programmed cell death.

Final Answer

The correct answer is apoptosis.
