For example, when you skin your knee, cells divide to replace old, dead, or damaged cells. Cells also divide so living things can grow. When organisms grow, it isn't because cells are getting larger. Organisms grow because cells are dividing to produce more and more cells.

All multicellular organisms use cell division for growth and the maintenance and repair of cells and tissues. Single-celled organisms use cell division as their method of reproduction. Somatic cells divide regularly; all human cells (except for the cells that produce eggs and sperm) are somatic cells.

The purpose of mitosis is to divide and replicate cells. What is interphase? Interphase is the cell growth and reproduction phase that is broken into three part: First Growth Phase, (G1) Synthesis Phase (S), and Second Growth Phase (G2). DNA is relaxed during all of Interphase.

Nuclear division divides the genetic material in the nucleus, while cytokinesis divides the cytoplasm.

The main functions of mitosis are growth and repair. Some cells once fully formed do not undergo cell division, such as nerve cells and muscle cells. Since you can never re-grow or repair these types of cells once they are mature, you must take care of the ones you have.

Mitosis cannot happen without cytokinesis. Mitosis is the process a cell goes through to produce 2 new cell nuclei. If mitosis happened but cytokineses did not, then one cell would have 2 nuclei in it. Cytokinesis is the splitting of the cytoplasm.

Eukaryotic cells must first divide their nucleus, followed by division of their cytoplasm, to complete cell division.

What is the function of the centrosome? The centrosome plays an important role during cell division, when a special "spindle" of microtubules is constructed for the purpose of moving chromosomes around the cell.

Mitosis is the process in cell division by which the nucleus of the cell divides (in a multiple phase), giving rise to two identical daughter cells. Mitosis happens in all eukaryotic cells (plants, animals, and fungi). It is the process of cell renewal and growth in a plant, animal or fungus.

Cells divide by mitosis for growth and repair. They divide by meiosis to produce gametes for sexual reproduction.

The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication of its DNA (DNA replication) to produce two daughter cells. ... During the final stage, cytokinesis, the chromosomes and cytoplasm separate into two new daughter cells.

mitosis / cell division. Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells.

['FIRST PART. CELLS CONTAIN DNA THAT IS PASSED CELL TO CELL DURING CELL DIVISION.', 'SECOND PART. CELLS ARE SIMILAR IN CHEMICAL COMPOSITION AND REACTIONS THAT MAINTAIN HOMEOSTASIS.', 'THIRD PART. ALL BASIC CHEMICAL AND PHYSIOLOGICAL FUNCTIONS ARE CARRIED OUT INSIDE THE CELL.', 'FOURTH PART.']

Cell division serves as a means of reproduction in unicellular organisms through binary fission. In multicellular organisms, cell division aids in the formation of gametes, which are cells that combine with others to form sexually produced offspring. ... The human body also repairs injuries by means of cell division.

Cell division consists of two phases— nuclear division followed by cytokinesis. Nuclear division divides the genetic material in the nucleus, while cytokinesis divides the cytoplasm.
