totipotence
Definition
Noun: The inherent capacity of a single cell, especially a fertilized egg or a plant cell, to divide, differentiate, and develop into a complete, new, and fully functional organism. This property represents the highest degree of developmental potential in biological systems.
Usage
"Totipotence" is a specialized biological term. It is used to describe the unique and powerful developmental capability of certain cells. It is most commonly applied in the contexts of embryology, developmental biology, and plant science.
Examples
- In many plants, a single cell can exhibit totipotence, allowing an entire new plant to be grown from a leaf cutting.
- The totipotence of the zygote is fundamental to the development of a complex multicellular organism from a single cell.
- Scientists study totipotence to understand the fundamental principles of cellular differentiation and development.
Advanced Usage
- "Retain totipotence": To maintain the full developmental capacity.
- Unlike animal cells, many plant cells retain their totipotence even when mature.
- "Loss of totipotence": The point at which a cell's potential becomes restricted to specific cell lineages.
- The loss of totipotence occurs early in animal embryonic development as cells begin to specialize.
Variants and Related Words
- Totipotent (adjective): Having the capability of totipotence.
- A totipotent cell has the potential to form all cell types in an organism.
- Totipotency (noun): A synonym for totipotence, used interchangeably.
- The experiment demonstrated the cell's totipotency.
Synonyms
- Developmental pluripotency (in a broad, sometimes less precise sense, though "pluripotence" is a distinct, more limited potential).
- Full developmental potential.
Antonyms
- Differentiation: The process by which a cell becomes specialized, losing its totipotence.
- Specialization: The state of being committed to a specific function.
- Unipotence: The potential of a cell to develop into only one cell type.
Noun
-
the ability of a cell to give rise to unlike cells and so to develop a new organism or part
-
animal cells lose their totipotency at an early stage in embryonic development
