What is the most important significance of mitosis?
Answer: 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 of damaged tissues.
Which is the most important stage of cell cycle?
Interphase is the most important stage of cell cycle. The cell stays in the interphase for maximum periods. During this phase the cell prepares itself for division. The cell undergoes cell growth and replication during this phase.
Why is G1 phase important?
The G1 phase is often referred to as the growth phase, because this is the time in which a cell grows. During this phase, the cell synthesizes various enzymes and nutrients that are needed later on for DNA replication and cell division. … The G1 phase is also when cells produce the most proteins.
What is the significance 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.
What are the two significance 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 happens in stages 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 …
