Question

The formation of cell plate occurs in ________ manner.

• A. centripetal manner
• B. centrifugal manner
• C. both centripetal and centrifugal manner
• D. none of these

Answer 1

The correct option is B centrifugal manner

Centripetal means moving towards the centre from the periphery.
Centrifugal means moving towards the periphery from the centre.
During mitosis, the division of the nucleus is followed by division of cytoplasm. During division of cytoplasm a new cell wall is laid in the centre. The process begins with formation of a cell plate which is the precursor to the cell wall. The cell plate grows from the centre to periphery. Hence, cell plate formation occurs in a centrifugal manner.
