Plant cell undergoes cell division to form two new cell. The below diagram represents a certain stage of the cell cycle of plant cells. Determine the step/stage of the cell cycle process that will happen just before the represented process starts.
Options
- ADiakinesis
- BKaryokinesis
- CDNA synthesis
- DCytokinesis
Correct answer
B. Karyokinesis
Step-by-step solution
Cell division phase of cell cycle has two stages - karyokinesis and cytokinesis. Karyokinesis deals with nuclear division where at the end of this stage two nuclei are formed. Following karyokinesis, cytokinesis occurs where the cytoplasm is divided in two resulting in formation of two new whole individual cells. The given diagram represent the cytokinesis stage of plant cell division. In it, the division occurs by making a cell plate in the cytoplasm between the two newly formed nuclei which later becomes the cell
