Which type of cell division is required for growth and repair of body and which type is involved in formation of gametes

Types of Cell Division Definition, Mitosis, Meiosis & Vs Cancer Introduction Cells are the most basic units of life, and every living organism is made up of one or more cells. These cells reproduce by copying their genetic information and undergoing cell division , where the parent cell gives rise to two daughter cells. There are three major types of cell division, which are: • Binary fission • Mitosis • Meiosis Whereas binary fission takes place in prokaryotic cells of simple single-celled organisms such as bacteria. Mitosis and meiosis take place in eukaryotic cells and are more advanced. Although there are differences between prokaryotes and eukaryotes, there are a number of features that are common during their processes of cell division. These include: • The replication of DNA, • The segregation of the original and the replica, • Binary fission is the type of cell division that takes place in prokaryotes ( In a similar fashion to eukaryotes, the genetic material of these cells is duplicated before division. As the prokaryote elongates, the two chromosomes attached to the Except in a case of mutation, the two resultant cells are identical. Eukaryotes Eukaryotic cells are more complicated given that they contain more organelles as compared to the prokaryotic cells. The cell cycle, which is composed of four main phases, is responsible for planning and the development of these cells. This cycle is also composed of all the steps required for the reproduction of a eukaryoti...

Cells divide and reproduce in two ways: mitosis and meiosis. Mitosis is a process of cell division that results in two genetically identical daughter cells developing from a single parent cell. Mitosis is used by single-celled organisms to reproduce; it is also used for the organic growth of tissues, fibers, and membranes. Meiosis, on the other hand, is the division of a Comparison chart Meiosis versus Mitosis comparison chart Meiosis Mitosis Definition A type of cellular reproduction in which the number of chromosomes are reduced by half through the separation of homologous chromosomes, producing two haploid cells. A process of asexual reproduction in which the cell divides into two daughter cells, with an equal number of chromosomes in each resulting Steps (Meiosis 1) Prophase I, Metaphase I, Anaphase I, Telophase I; (Meiosis 2) Prophase II, Metaphase II, Anaphase II and Telophase II.

Meiosis does not occur in archaea or bacteria because they reproduce asexually. Mitosis occurs in all organisms.

Cell division: It is the process of formation of two daughter cells from a single cell following a series of steps. Mitosis: • It is also known as equational division because it forms exactly a xerox copy of the previous cell. • The DNA amount remains constant and also the chromosome number remains constant in a species. • This is the cell division required for growth and repair of the body as it adds up identical cells to a certain part of the body increasing its size. • In case of injuries where the cells are damaged, mitosis occurs to repair those regions. Meiosis: • It is known as the reductional division as the chromosome number reduces to half in this type of division. • It can form gametes as gametes need to be haploid cells so that they can fuse together in order to form a diploid zygote which will give rise to a new offspring.

Dear student, The type of the cell division required for the growth and repair of the body is mitosis which is also called as the equational division in which the chromosomes number remains the same and thus same type of the cells are formed by the mitosis division. For the formation of the gametes, the meiotic division is required which is also called as the reductional division in which the chromosome number is reduced to half. Thus, it occurs in the diploid cells to form the haploid gametes like sperm and ovum. Regards

(Image by Lothar Schermelleh) Sometimes you accidentally bite your lip or skin your knee, but in a matter of days the wound heals. Is it magic? Or, is there another explanation? Every day, every hour, every second one of the most important events in life is going on in your body—cells are dividing. When cells divide, they make new cells. A single cell divides to make two cells and these two cells then divide to make four cells, and so on. We call this process "cell division" and "cell reproduction," because new cells are formed when old cells divide. The ability of cells to divide is unique for living organisms. Why Do Cells Divide? Cells divide for many reasons. For example, when you skin your knee, cells divide to replace old, dead, or damaged cells. Cells also divide so living things can grow. When organisms grow, it isn't because cells are getting larger. Organisms grow because cells are dividing to produce more and more cells. In human bodies, nearly two trillion cells divide every day. Watch cells divide in this time lapse video of an animal cell (top) and an E. coli bacteria cell (bottom). The video compresses 30 hours of mitotic cell division into a few seconds. (Video by the National Institute of Genetics) How Many Cells Are in Your Body? You and I began as a single cell, or what you would call an egg. By the time you are an adult, you will have trillions of cells. That number depends on th...

\( \newcommand\) • • • • • • One parent or two? That is the main difference between sexual and asexual reproduction. Sexual reproduction just means combining genetic material from two parents. Asexual reproduction produces offspring genetically identical to the one parent. Reproduction: Asexual vs. Sexual Cell division is how organisms grow and repair themselves. It is also how many organisms produce offspring. For many single-celled organisms, reproduction is a similar process. The parent cell simply divides to form two daughter cells that are identical to the parent. In many other organisms, two parents are involved, and the offspring are not identical to the parents. In fact, each offspring is unique. Look at the family in Figure Family Portrait: Mother, Daughter, Father, and Son. Children resemble their parents, but they are never identical to them. Do you know why this is the case? Reproduction is the process by which organisms give rise to offspring. It is one of the defining characteristics of living things. There are two basic types of reproduction: asexual reproduction and sexual reproduction. Asexual Reproduction Asexual reproduction involves a single parent. It results in offspring that are genetically identical to each other and to the parent. All prokaryotes and some eukaryotes reproduce this way. There are several different methods of asexual reproduction. They include binary fission, fragmentation, and budding. • Binary fission occurs when a parent cell spli...
