Question

Examining a cell in the microscope, you can see a cell plate beginning to develop across the middle of the cell and nuclei reforming at opposite poles of the cell. This cell is most likely a

• A. Bacterial cell dividing
• B. Animal cell in the S phase of the cell cycle
• C. Plant cell in the process of cytokinesis
• D. Animal cell in the process of cytokinesis

Answer 1

The correct option is C Plant cell in the process of cytokinesis

• Cytokinesis is the process of formation of cell after the division of cells in the cell cycle.
• After the telophase of the mitosis where the genetic material is present in each daughter cell the nuclear membrane in the cell will start appearing again which is known as karyokinesis.
• In animals cell which do not have cell wall but only plasma membrane the cell will start constricting from the ends and meet in the middle at the end after which the cells will be separated.
• While in plant cells which have cell wall outside the cell membrane, the formation of cell wall in the young daughter cell takes place from the middle of cytoplasm where the cells are dividing.
• This cell plate starts from the middle and moves towards the end forming 2 cells surrounded by cell wall.
  
• Therefore the answer 'Plant cell in the process of cytokinesis' is correct.
