What is formed by the division of the cytoplasm at the end of cell division?

During cell division, specifically at the end of the process known as cytokinesis, the cytoplasm of a parent cell is divided to form new cells. This process ensures that the genetic material is evenly split and that each new cell has the necessary components to function independently.

As a result of cytokinesis, two new daughter cells are formed, each with its own nucleus and an identical set of chromosomes. This is crucial for the continuity of cellular life and the maintenance of genetic information across generations of cells. The formation of daughter cells is a key event not just in mitosis, but also in meiosis, where gametes are formed.

The other processes mentioned in the question do not directly result from the division of the cytoplasm. For instance, nuclei refer to the organelles that house the cell's genetic material but are not themselves formed by cytokinesis. A cell wall, present in plant cells, also does not arise from cytoplasmic division but is instead constructed as part of the cellular architecture during the formation of new cells. Spindle fibers are involved in the separation of chromosomes during cell division, but they do not persist after cytokinesis is complete. Hence, the correct answer identifies the end result of cytoplasmic division as the formation of
