Which characteristic allows a cell to be classified as totipotent?

• A. Ability to undergo apoptosis
• B. Ability to form only muscle cells
• C. Ability to divide rapidly
• D. Ability to differentiate into any cell type

Answer: (D)

Verified step by step guidance

1. Understand the concept of totipotency: Totipotency is the ability of a single cell to divide and produce all of the differentiated cells in an organism, including both the somatic cells and the germ cells.
2. Identify the key characteristic of totipotent cells: Totipotent cells have the potential to differentiate into any cell type, which means they can give rise to a complete organism.
3. Differentiate between totipotent and other types of stem cells: Unlike pluripotent cells, which can form almost any cell type but not an entire organism, totipotent cells can form all cell types, including extraembryonic tissues.
4. Evaluate the options given in the problem: The ability to undergo apoptosis, form only muscle cells, or divide rapidly are not exclusive characteristics of totipotent cells.
5. Conclude with the correct characteristic: The defining feature of a totipotent cell is its ability to differentiate into any cell type, which is the correct answer to the problem.
