How Do Plant Cells Reproduce?
How Do Plant Cells Reproduce?. All eukaryotic cells -- cells that contain genetic material in a nucleus -- reproduce through cell division to replace old, worn-out cells and make the organism larger and more complex. The basic phases of mitosis are prophase, metaphase, anaphase, telophase and cytokinesis.
All eukaryotic cells -- cells that contain genetic material in a nucleus -- reproduce through cell division to replace old, worn-out cells and make the organism larger and more complex. The basic phases of mitosis are prophase, metaphase, anaphase, telophase and cytokinesis.
Prophase
During prophase, the cell's chromatids -- strands that contain DNA -- become thicker and more visible, and the nuclear membrane dissolves. Centrosomes -- structures that produce spindle fibers -- form and begin to move to opposite ends of the cell. The spindle fibers attach to sister chromatids.
Metaphase
In metaphase, the chromatids line up in the center of the cell, between the centrosomes.
Anaphase
During anaphase, the spindle fibers shorten, pulling sister chromatids apart toward opposite ends of the cell.
Telophase
During telophase, the chromatids -- now called chromosomes -- become thinner and less visible, and a new nuclear membrane forms to contain them.
Cytokinesis
In cytokinesis, a cell plate forms through the center of the cell, dividing the cell into two. Following cytokinesis, the cells go through a resting period called interphase.
