How do animal 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
A. By the appearance of a furrow in the plasma membrane
Step-by-step solution
In an animal cell, this is achieved by the appearance of a furrow in the plasma membrane. The furrow gradually deepens and ultimately joins in the centre dividing the cell cytoplasm into two. 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 p
