Question

Are there spindle fibers in plant cells?

Answer 1

Spindle fibers:

1. Spindle fibers are a type of protein that divides a cell's genetic material.
2. During both types of nuclear division, mitosis and meiosis, the spindle is required to evenly divide the chromosomes in a mother cell into two daughter cells.
3. Kinetochore and interpolar fibers are the two types of spindle fibers.
4. From one spindle to the next, the interpolar spreads indefinitely.
5. From the pole to the kinetochore, the kinetochore fiber stretches.
6. Plant cells do not have centrioles, although they can still create mitotic spindles.
7. During mitosis, chromosomes, spindle fibers, and kinetochores all play important roles.
8. Centrosomes, which play a key role in spindle formation, are completely absent in plant cells.
9. To carry out chromosomal segregation, plants have evolved novel methods.
10. Recent research on plant mitosis has revealed that plants use a form of “spindle self-organization.”
11. Plant cells lack centrioles, yet the centrosome area can form a mitotic spindle.
