Explanation: Mitosis is used to grow new tissues an repair the wounded ones. Meiosis is used to produce gametes which eventually fuse together to make zygote that will develop into a new individual.
Why do our cells need to undergo 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. … Meiosis begins following one round of DNA replication in cells in the male or female sex organs.
Why do cells need to undergo mitosis?
Mitosis is a process where a single cell divides into two identical daughter cells (cell division). … The major purpose of mitosis is for growth and to replace worn out cells.
Why do cells undergo mitosis quizlet?
Cells undergo mitosis to replace old cells, repair damaged tissues, and for the growth of an organism.
Do cells go through mitosis and meiosis?
There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life.
Why do our cells need to undergo mitosis and meiosis quizlet?
Cells undergo mitosis for growth and repair. … a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cells. Cells undergo meiosis to produce haploid cells.
Which of the following are reasons that cells undergo cell division?
Cells divide for two reasons:
- Growth. We all started out as a single cell; the fusion of a sperm from dad and an egg from mom. …
- Repair. Cells are constantly wearing out and getting damaged, and unless an organism replaces them at least as fast as they are lost, a gradual deterioration will occur.
What would happen without mitosis and meiosis?
Instead of mitosis, gametes reproduce through a process called meiosis. … Without meiosis, organisms would not be able to reproduce effectively. If organisms did not undergo mitosis, then they would not be able to grow and replace worn-out cells. They are two of the most important cellular process in existence.
What is one of the very important differences between mitosis and meiosis?
Most important difference is that Mitosis results in 2 daughter cells with same number of chromosomes( Takes place in somatic cells) whereas Meiosis is a reduction division where the chromosome number is halved in the daughter cells (takes place in reproductive cells).
What happens to the cell 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.
