Answer
(i) Prophase.
Chromosomes have duplicated as paired chromatids connected by centromere. Centrosome split into centrioles and are moving to opposite poles. Nuclear membrane and nucleolus disappearing.
(ii) The next stage is Metaphase. It's diagram is shown below:
(iii) Two differences between mitotic division in an animal cell and plant cell are:
| Animal cell | Plant cell |
|---|---|
| Asters are formed. | Asters are not formed. |
| Cytokinesis by formation of furrow in the cytoplasm. | Cytokinesis by cell plate formation. |
(iv) Type of cell division is mentioned below:
A. Mitosis
B. Meiosis
