How is cytokinesis achieved in a plant cell?
Options
- ABy the appearance of a furrow in the plasma membrane
- BBy the inextensibility of cell wall
- CBy the segregation of duplicated chromosomes
- DBy the separation of cytoplasm
Correct answer
B. By the inextensibility of cell wall
Step-by-step solution
Plant cells however, are enclosed by a relatively inextensible cell wall, thererfore they undergo cytokinesis by a different mechanism. In plant cells, wall formation starts in the centre of the cell and grows outward to meet the existing lateral walls. The formation of the new cell wall begins with the formation of a simple precursor, called the cell-plate that represents the middle lamella between the walls of two adjacent cells. At the time of cytoplasmic division, organelles like mitochondria and plastids get d
