mother cell
Học thuậtThân thiện
Definition
Noun: A mother cell is a biological cell that divides or differentiates to produce other cells, typically daughter cells of a different type or function. It serves as the origin or precursor in cellular development.
Examples
- Under the microscope, we observed the mother cell dividing into two specialized daughter cells.
- In plant biology, a pollen mother cell undergoes meiosis to produce pollen grains.
- The research focused on how the mother cell gives rise to a variety of cell types in the tissue.
Advanced Usage
- Stem cells as mother cells: While not always synonymous, pluripotent stem cells can be considered a classic example of a mother cell, as they have the potential to develop into many different cell types in the body.
- Asymmetrical division: A key concept is that a mother cell often divides asymmetrically, producing two daughter cells with different fates or properties.
Variants and Related Words
- Parent cell: A more general synonym often used interchangeably with mother cell, especially in the context of cell division.
- Progenitor cell: A cell that, like a mother cell, is committed to differentiating into a specific cell type but has a more limited capacity for self-renewal than a stem cell.
- Daughter cell: The direct product cell resulting from the division of a mother cell.
Synonyms
- Progenitor cell
- Precursor cell
- Parent cell
Notes on Meaning
The term mother cell is specifically used in developmental biology and cytology. It emphasizes the generative and origin role of the cell. It is distinct from a general "dividing cell" because it implies the production of cells that are different or will undergo further specialization.
Noun
- cell from which another cell of an organism (usually of a different sort) develops
- a sperm cell develops from a sperm mother cell
