Assertion : Cytokinesis is different in animal and plant cells. Reason : Vesicles of golgi apparatus from cell plate in plant cells.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect.
Explanation:
Cytokinesis is the division of protoplast of a cell after the nuclear division. Each daughter cell comes to have its own nucleus. In animal cells, the furrow deepens centripetally and cleaves the cell into daughters, each having a daughter nucleus. The method is known as cleavage cytokinesis. In plant cells, cytokinesis takes place by two methods, cleavage and cell plate. Small vesicles produced by golgi apparatus collect at the equator of the phragmoplast. The membrane of the vesicles fuse to form two sheets on which enclose a matrix or film. Soon the film becomes solidified to form cell plate or middle lamella. The daughter protoplasts deposit cellulose, hemicelluloses and pectin on either side of the cell plate. They form the primary wall.

Which of the following statement(s) is/are true?
1 Cell plate represents the middle lamella between the walls of two adjacent cells.
2 At the time of cytokinesis, organelles like mitochondria and plastids get distributed between the daughter cells.
3 Cytokinesis in plant cell is centrifugal and takes place by cell-plate formation while animal cells by furrowing/ cleavage and is centripetal.
