Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells. The word “mitosis” means “threads,” and it refers to the threadlike appearance of chromosomes as the cell prepares to divide.
What is the most correct definition of mitosis?
1 : a process that takes place in the nucleus of a dividing cell, involves typically a series of steps consisting of prophase, metaphase, anaphase, and telophase, and results in the formation of two new nuclei each having the same number of chromosomes as the parent nucleus — compare meiosis.
How would you describe the phases of mitosis?
Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. … These phases occur in strict sequential order, and cytokinesis – the process of dividing the cell contents to make two new cells – starts in anaphase or telophase.
How do you describe meiosis?
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. … The process is split into meiosis I and meiosis II, and both meiotic divisions have multiple phases.
What does mitosis mean in kid terms?
The process of cell division, during which one cell gives rise to two identical daughter cells, is called mitosis. The process of mitosis is essential to life: it provides new cells for growth and replaces old and dying cells.
What is a sentence for mitosis?
1) The chromosomes duplicated in mitosis. 2) In just one session, Mitosis recorded eight songs. 3) Mitosis lasted two years during the period between the pair leaving the sixth form and attending university. 4) Thus, in effect, before mitosis a normal body cell of an animal contains four functional sets of chromosomes.
What are the 4 stages of mitosis and what happens in each?
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 is mitosis Class 11?
Hint: Mitosis is the stage in the cell cycle in which the newly formed DNA splits and two new cells are formed with the same number and type of chromosomes as the nucleus of the parent cell. Mitosis is an asexual reproduction mechanism found in single-celled species.
What happens during mitosis?
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. … Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division.
How do you explain meiosis to a child?
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females. During meiosis one cell? divides twice to form four daughter cells.
Does mitosis create two daughter cells?
Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.
How is mitosis different from meiosis?
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.
What are some examples of mitosis in the human body?
One example of mitosis in the human body is the healing of scrapes or cuts. After the scab forms over the injury new skin grows underneath the scab….
What is a real life example of mitosis?
Some organisms use mitosis to replace body parts. For example starfish replace lost arms by mitosis. Some organisms such as the hydra use mitosis to produce genetically identical offspring. The process is known as budding.
Where does the mitosis take place?
Mitosis occurs in somatic cells; this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell.
