A stage in cell division is shown in the figure. Select the answer which gives correct identification of the stage with its characteristics.
Correct answer: C. Telophase: Nuclear envelope reforms, Golgi complex reforms
- A. Cytokinesis: Cell plate formed, mitochondria distributed between two daughter cells
- B. Telophase: Endoplasmic reticulum and nucleolus not reformed yet
- C. Telophase: Nuclear envelope reforms, Golgi complex reforms
- D. Late anaphase: Chromosomes move away from equatorial plate, Golgi complex not present
Explanation
The figure given in the question shows a stage of mitotic cell division called the telophase stage. The individual chromosomes are no longer seen and chromatin material tends to collect in a mass at the two poles. This is the stage that shows the following key events: -Chromosomes cluster at opposite spindle poles and their identity is lost as discrete elements. - Nuclear envelope assembles around the chromosome clusters. - Nucleolus, Golgi complex and ER reform.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
