The correct answer is the option #3: A cub tiger begins to grow. The stage in which the cub tiger begins to grown is one of the most important stages in the process of mitosis, since the cells are being divided in order to help the cub to grow taller and larger.
What is the main importance of mitosis?
Replacement and regeneration of new cells– Regeneration and replacement of worn-out and damaged tissues is a very important function of mitosis in living organisms. Mitosis helps in the production of identical copies of cells and thus helps in repairing the damaged tissue or replacing the worn-out cells.
What are the five stages of mitosis?
These phases are prophase, prometaphase, metaphase, anaphase, and telophase. Cytokinesis is the final physical cell division that follows telophase, and is therefore sometimes considered a sixth phase of mitosis.
What are two most important goals of interphase?
Interphase is also important for mitosis and cytokinesis because in G1, the cell begins growth and development, where the cell grows in size and synthesizes proteins and messenger RNA, which conveys genetic information from DNA to the ribosomes; this prepares the cell for the following steps towards mitosis.
What occurs in each phase of mitosis?
1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3) Anaphase: sister chromatids are pulled to opposite poles of the cell 4) Telophase: nuclear envelope …
What are the five importance of mitosis?
Significance of Mitosis
It helps in maintaining the same number of chromosomes in daughter cells after division. It is responsible for growth and development of multicellular organisms. It helps in repairing damaged tissues. It helps the cell to maintain proper size.
What is the importance of mitosis and meiosis?
Mitosis and meiosis both involve cells dividing to make new cells. This makes them both vital processes for the existence of living things that reproduce sexually. Meiosis makes the cells needed for sexual reproduction to occur, and mitosis replicates non-sex cells needed for growth and development.
