Answer:

The Cell membrane plays its role in cell division by sustaining its organelles and division of its self to separate cytokinesis

Nucleus

is the control center of the cell. This is because the nucleus contains chromosomes that are made up of long strands of molecules called DNA. The DNA carries messages for how to put together proteins. Proteins, in turn, are used for structure (skin, muscle). Also, enzymes are proteins that are involved in all the chemical reactions of the cell. They are catalysts, which speed up the rate of the chemical reactions that are going on in the cell.

Centrioles

are paired organelles that are in the cytoplasm only to take part in cell division. As you will see in the diagrams of cell division first they duplicate and then each pair moves to a place called the pole of the cell and seems to anchor the spindle fibers.

Microtubules

are miniature tubes that act as the skeleton of the cell, just like our skeleton holds us together. In Cell division, the microtubules rearrange themselves into spindle fibers that stretch between the centrioles and attach to the chromosomes to move them around, as you will see in the diagrams contained in the mitosis section.

Answer:

Cell membrane

  • It provides protection. It also maintains a constant environment within the cell, and the membrane serves a variety of purposes. The first is to move nutrients into the cell, and the second is to transport harmful chemicals out.

Nucleus

  • It disassembles and re-forms each time most cells divide.

Centrioles

  • These spindle fibers act as guides for the alignment of the chromosomes as they separate later during the process of cell division.

Microtubules

  • Microtubules play an important role in cell division by contributing to the formation of the mitotic spindle, which plays a part in the migration of duplicated chromosomes during anaphase.
