Definition

1. Noun (Biology, Cell Biology):
   • Centrosome: A small, non-membrane-bound organelle located near the nucleus in animal cells, serving as the main microtubule-organizing center (MTOC). It plays a crucial role in cell division by organizing the mitotic spindle.

Usage Examples

• Noun:
  • Trung thể đóng vai trò quan trọng trong quá trình phân bào. (The centrosome plays an important role in the process of cell division.)
  • Các tế bào động vật thường chứa một trung thể. (Animal cells usually contain one centrosome.)
  • Sự nhân đôi của trung thể xảy ra trước khi phân chia tế bào. (The duplication of the centrosome occurs before cell division.)

Advanced Usage

• In scientific literature, the term is used specifically in the context of eukaryotic cell biology and is not typically applied to plant cells, which lack distinct centrosomes.

Variants and Related Words

• Trung tử (n): Centriole. A cylindrical cell structure, composed mainly of tubulin, found within the centrosome.
  • Mỗi trung thể thường chứa hai trung tử. (Each centrosome typically contains two centrioles.)

Synonyms

• Centrosome: The primary and direct synonym in English scientific terminology.

Related Terms (Not Synonyms)

• Bộ máy phân bào: Mitotic spindle. The structure formed by microtubules, organized by the centrosome, to separate chromosomes.
• Thể cực: Pole (in cell division). The area of the cell where the centrosome is located during mitosis.
