Step 1:
Stage 1: Prophase

In prophase, chromosomes condense and become visible, and the nuclear envelope begins to break down. For example, in onion root tip cells, chromosomes can be seen as distinct structures under a microscope.

Step 2:
Stage 2: Metaphase

During metaphase, chromosomes align at the cell's equatorial plate. In animal cells, such as those in whitefish blastula, chromosomes line up in the center before being separated.

Step 3:
Stage 3: Anaphase

In anaphase, sister chromatids are pulled apart toward opposite poles of the cell. For example, in human somatic cells, spindle fibers separate the chromatids during this stage.

Step 4:
Stage 4: Telophase

Telophase involves the reformation of the nuclear envelope around each set of chromosomes, which begin to de-condense. In plant cells, such as those in root tips, new nuclei form at each pole.

Step 5:
Stage 5: Cytokinesis

Cytokinesis is the division of the cytoplasm, resulting in two daughter cells. In animal cells, this occurs through cleavage furrow formation, while in plant cells, a cell plate forms.

Final Answer

The stages of mitosis are prophase, metaphase, anaphase, telophase, and cytokinesis, each with observable examples in plant and animal cells.
