Do plant cells have spindle fibers?

Yes, plant cells have spindle fibers during cell division.

Spindle fibers are structures made of microtubules that help in separating chromosomes during cell division. In animal cells, spindle fibers form from centrioles. However, plant cells do not have centrioles. 

Instead, spindle fibers form directly from the nuclear region during mitosis or meiosis. These fibers attach to the chromosomes and pull them apart into daughter cells. This ensures each new cell gets the correct number of chromosomes. Thus, spindle fibers are essential for proper cell division in both plant and animal cells.
