Detailed explanation-1: -The type of cell exhibiting the formation of a cell plate across the middle of its cell and nuclei forming at opposite ends of the cell is a plant cell undergoing cytokinesis.

Detailed explanation-2: -Nucleoli disappear and each chromosome is now an identical sister chromatid. The formation of a cell plate is beginning across the middle of a cell and nuclei are reforming at opposite ends of the cell.

Detailed explanation-3: -Although this is a temporal chain of events, a developing cell plate may be simultaneously involved in all of these stages because cell plate formation starts in the cell center and then progresses centrifugally towards the cell periphery.

Detailed explanation-4: -The assembly of the cell plate begins in late anaphase and is guided by a structure called the phragmoplast, which contains the remaining overlap microtubules of the mitotic spindle that interdigitate at their growing plus ends.

Detailed explanation-5: -The cell plate arises from small Golgi-derived vesicles that coalesce in a plane across the equator of the late telophase spindle to form a disk-shaped structure. In this process, each vesicle contributes its membrane to the forming cell…
