Mitosis:

This is the process where a single cell divides into two identical daughter cells each having the same number of chromosomes as the parent nucleus.

Spindle Fibers: These are protein structures that form early in mitosis or meiosis and play a vital role in cell division. They help move chromosome pairs apart to opposite ends of a cell.

Eukaryotic Cells:

These are complex cells with a nucleus and other organelles enclosed within membranes. Animals, plants, fungi, and protists have eukaryotic cells.
