QQuestion
Compare the steps of mitosis in plant cells and animal cells and select which are correct:
| Mitosis in plant cell | Mitosis in animal cell |
| I. Spindle is formed from the cytoplasm. | I. Spindle is formed from centrioles or asters. |
| II. Cytokinesis occurs by cell plate formation. | II. Cytokinesis occurs by cleavage furrow formation. |
| III. Centrosomes are not involved. | III. Centrosomes form from centrioles and are involved in mitosis. |
|
IV. Division of cytoplasm occurs through the formation of a cell plate. |
IV. Division of cytoplasm occurs through furrow formation. |
Which are correct?
(a) I, IV
(b) II, IV
(c) II, III
(d) III, IV
✓Answer
(b) II, IV
Explanation:
In plant cells, cytokinesis happens by cell plate formation (II), and division of cytoplasm takes place through cell plate (IV). In animal cells, cytokinesis happens by furrow (cleavage) formation and involves the centrioles. Thus, options II and IV are correct for plant mitosis.
