How do plant cells undergo cytokinesis?
Options
- ABy the appearance of a furrow in the plasma membrane
- BBy the formation of a simple precursor called the cell-plate
- CBy the formation of a new cell wall that grows outward to meet the existing lateral walls
- DBy the formation of a syncytium
Correct answer
C. By the formation of a new cell wall that grows outward to meet the existing lateral walls
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
