The process in which body cells are duplicated in order to grow and repair body tissues is called cell division or mitosis.
The process in which body cells are duplicated in order to grow and repair body tissues is called cell division. Specifically, the type of cell division that is responsible for this process is called mitosis.
To understand how cell division works, let's break it down into steps:
1. Interphase: Before cell division can occur, the cell goes through a phase called interphase. During interphase, the cell prepares for division by growing, making new organelles, and duplicating its DNA.
2. Prophase: In this stage, the duplicated chromosomes inside the cell condense and become visible. The nuclear membrane starts to break down, and the centrosomes move to opposite poles of the cell.
3. Metaphase: During metaphase, the chromosomes line up along the center of the cell. The spindle fibers, which emerge from the centrosomes, attach to each chromosome's centromere.
4. Anaphase: In anaphase, the spindle fibers shorten and pull the sister chromatids apart. They move towards opposite poles of the cell.
5. Telophase: During telophase, the chromosomes reach opposite poles of the cell, and a new nuclear membrane starts forming around each set of chromosomes. The chromosomes begin to decondense.
6. Cytokinesis: Cytokinesis is the final stage of cell division. It involves dividing the cytoplasm and organelles to form two daughter cells. In animal cells, a structure called the cleavage furrow forms and pinches the cell membrane inward until the cell splits in two. In plant cells, a cell plate forms in the middle of the cell, which eventually becomes a new cell wall.
By undergoing this process, cells can generate new cells, allowing for the growth and repair of body tissues.
