2. Verb:

   • To form into a nucleus; to act as a nucleus for formation or growth: The process of coming together to form a central core or initial point of development, often around which further growth or organization occurs.

Examples of Usage

• Adjective:

  • Eukaryotic cells are nucleate, unlike prokaryotic cells.
  • The nucleate region of the cytoplasm showed high activity.

• Verb:

  • In crystallization, impurities can cause the solution to nucleate more rapidly.
  • The particles began to nucleate, forming the seed of a new crystal structure.

Advanced Usage

• "Nucleate boiling": A phase-change heat transfer process where vapor bubbles form at discrete points (nucleation sites) on a heated surface.
