Mitosis: Stages and Significance · NCERT Biology

Why can plant cells not undergo cytokinesis by the furrowing method?

  1. They lack centrioles for spindle formation.
  2. They have a large central vacuole blocking division.
  3. They have a rigid, inextensible cell wall.
  4. They contain more DNA than animal cells.
Show answer and explanation

Correct answer: They have a rigid, inextensible cell wall.

Plant cells are encased in a rigid, inextensible cell wall that prevents the membrane from constricting. Instead, they divide by forming a cell plate that grows from the center toward the periphery.
