How does the cell plate divide the plant cell into two daughter cells?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
The cell plate forms at the centre of the cell and grows centrifugally (outward) toward the lateral walls, ultimately dividing the cell into two halves.
Explanation: In plant cytokinesis:
- Phragmoplast (microtubule structure) forms at the equator
- Golgi-derived vesicles carry cell wall materials (pectin, cellulose)
- Vesicles fuse to form the cell plate
- Cell plate expands outward until it fuses with the parental cell wall
This differs from animal cytokinesis, which occurs via cleavage furrow formation.
