centrioles
Centrioles. They are visible during metaphase, the second stage of mitosis. Added: Centrosomes. Centrioles are present in animal cells but are, seemingly, not needed to mount a spindle apparatus. Plant cells get along very well without centrioles.
In the laboratory, chromosomes can be separated according to length by the electric field of a gel electrophoresis apparatus. The separation of a chromosome into individual units during cell division (mitosis or meiosis) is caused by microtubules which attach the centromere to opposite end of the cell, pulling the two chromatids apart as the cell divides.
Protein synthesis is essential for the cell cycle because it produces the proteins needed for cell growth, division, and repair. During different phases of the cell cycle, specific proteins are synthesized to regulate processes such as DNA replication, cell division, and cell signaling. This ensures that the cell cycle progresses smoothly and accurately.
The organelles and molecules needed for cell division are formed during the G2 phase of the cell cycle, after DNA replication has occurred during the S phase. This is a crucial preparation phase for mitosis, where the cell ensures it has all the necessary components for successful division.

The structure that disappears during telophase is the mitotic spindle, which is responsible for separating the sister chromatids during cell division. As the cell prepares to complete division, the mitotic spindle breaks down and is no longer needed.
Collagen fibers is needed to reach the break and to connect the end of broken bones. The collagen fibers are produced by Fibroblasts.

Meiosis produces the sperm and egg cells needed for reproduction. Only cells in the ovaries or testes undergo meiosis.

Why is THE nucleus needed for cell division? well, THE nucleus is needed because it contains DNA, the building blocks and director of your cells.....

Plants have to utilize solar energy during photosynthesis because it is needed to create the chemical reaction. This reaction produces glucose and oxygen.
Particularly with cotton thread, if it is too dry it will be brittle and the fibers will break during sinning. A cool humid climate is needed to prevent this.
