In plant cells, cytokinesis is accomplished by the formation of a:

Answer: Cell plate.

A Cleavage furrow
B Cell plate
C Contractile ring
D Centriole

Correct answer: B. Cell plate

Explanation: Plant cells divide the cytoplasm by laying down a cell plate from the centre outward; animal cells pinch inward with a cleavage furrow.

The cell cycle: G₁ (growth and preparation), S (DNA replication, chromosome number stays 2n but DNA content doubles), G₂ (final checks before division), and M (mitosis itself) - together, G₁+S+G₂ make up interphase.

Concept context

Mitosis and meiosis: how cells divide for growth, repair, and reproduction.
