NEETBotanyCell Cycle and Cell Division
How is the cell itself divided into two daughter cells at the end of mitosis?
Options
- ABy the segregation of duplicated chromosomes
- BBy the separation of cytoplasm
- CBy the appearance of a furrow in the plasma membrane
- DBy the inextensibility of cell wall
Correct answer
B. By the separation of cytoplasm
Step-by-step solution
Mitosis accomplishes not only the segregation of duplicated chromosomes into daughter nuclei (karyokinesis), but the cell itself is divided into two daughter cells by the separation of cytoplasm called cytokinesis at the end of which cell division gets completed. 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 c
