Introduction to Mitosis and Meiosis
Cell division is a fundamental process for life. It is useful not only to generate new cells but also to help in growth and development. This cell division can take place through 2 different modes - Mitosis and Meiosis. We are about to look at a few characteristics, the basic definitions, and the difference between mitosis and meiosis. Cell reproduction is the process of creating new species using a single-parent cell. However, this process is different in unicellular and multicellular organisms. Unicellular organisms perform cell reproduction or division to generate daughter cells. Multicellular organisms perform cell division to enhance growth and replace worn-out cells from the body. To put it straight, mitosis creates new body cells, whereas meiosis generates sperm and egg cells. Mitosis Overview
Meiosis Overview
Differences Between Mitosis and Meiosis in DetailMitosis is a core process that replicates all of its content, including duplication of its chromosomes. The result is two identical daughter cells. Mitosis is a critical process to life, and hence this is controlled by several genes. If the genes are not regulated properly, it might cause serious health issues in humans, such as cancer. Meiosis, on the other side, will create copies that have the same number of chromosomes in humans (in all generations). Meiosis is a two-step procedure, reducing the chromosome number by half. The result of this process is the formation of egg and sperm cells, with chromosome counts from 46 to 23. This is a reason why the human embryo has 46 chromosomes from birth (conception of egg and sperm). Chances are likely in meiosis to exhibit genetic variations from DNA shuffling. Following is a table to quickly describe the differences in mitosis vs meiosis. Difference Between Mitosis and Meiosis Table in Tabulated Form
In case of time constraints, students can refer to this table directly. This table will also come in handy while revising the topic. You may get information about many such topics of Biology on Vedantu's website for free. Similarities Between Mitosis and MeiosisApart from its cell division or reproductive processes, there are 3-4 similarities between meiosis and mitosis. DNA synthesis is primarily common to both. If already formed, the cardiac tissues and nervous system cells will never replicate their daughter/sister cells either through meiosis or mitosis. Both these methods of reproduction are visible under an electron microscope. Fun Facts about MitosisSome very interesting facts about Mitosis are given below to make the learning process interesting for you:

ConclusionBoth mitosis and meiosis have their roles in human development and genetic message transmission. Credits to ‘Walther Flemming’ for the discovery of mitosis and helping new cells grow and nurture. Also, thanks to the brain of Oscar Hertwig for uncovering meiosis and making continuity of required cells possible with definite DNA variants.

Recently Updated Pages Recently Updated Pages What are 5 differences between meiosis and mitosis?Mitosis involves the division of body cells, while meiosis involves the division of sex cells. The division of a cell occurs once in mitosis but twice in meiosis. Two daughter cells are produced after mitosis and cytoplasmic division, while four daughter cells are produced after meiosis.
What are 3 major differences between mitosis and meiosis?Mitosis consists of one stage whereas meiosis consists of two stages. Mitosis produces diploid cells (46 chromosomes) whereas meiosis produces haploid cells (23 chromosomes). Mitosis produces two identical daughter cells whereas meiosis produces four genetically different daughter cells.
