Mitosis and meiosis are two processes by which eukaryotic cells may divide and share several similarities: they are both preceded by interphase (which includes dna replication) they both divide according to a common pathway (prophase → metaphase → anaphase → telophase) they both split their cells via. A comparison of mitosis versus meiosis reveals several key differences.

Mitosis is more common than meiosis and has a wider variety of functions meiosis has a narrow but significant purpose: assisting sexual reproduction in mitosis, a cell makes an exact clone of itself this process is what is behind the growth of children into adults, the healing of cuts and bruises, and even the regrowth of. Mitosis - when cells split apart eventually cells need to duplicate there are two main methods of replication, mitosis and meiosis this tutorial will talk about mitosis the big idea to remember is that mitosis is the simple duplication of a cell and all of its parts it duplicates its dna and the two new cells (daughter cells) have. This free course, meiosis and mitosis, looks at how units of inheritance are transmitted from one generation to the next first you will look at what happens to the chromosomes of animals and plants during the process of sexual reproduction then you will examine how genes are transmitted in particular patterns from. The cell cycle actively dividing eukaryote cells pass through a series of stages known collectively as the cell cycle: two gap phases (g1 and g2) an s (for synthesis) phase, in which the genetic material is duplicated and an m phase, in which mitosis partitions the genetic material and the cell divides 22-cell-cyclegif.

Cell division: mitosis and meiosis start science and global issues: biology – genetics: feeding the world, activities 3 and 13 cell division: mitosis and meiosis parent cells that undergo mitosis produce two identical daughter cells this occurs in humans and other multicellular organisms producing new cells it is also. Mitosis and meiosis cells give rise to new cells through a process called cell division cell division is an important and unique event that occurs in all living organism for two mitosis: during mitosis, the cells go through 5 stages: prophase, metaphase, anaphase, telophase, and cytokinesis see more biology topics.

  • 96 cell division – mitosis and meiosis mitosis is a nuclear division giving rise to genetically identical cells in which the chromosome number is maintained by the exact duplication of chromosome meiosis is a reduction division in which the chromosome number is halved from diploid to haploid picture mitosis picture.
  • Where do cells come from 3d image of a mouse cell in the final stages of cell division (telophase) (image by lothar schermelleh.
  • At this stage in the meiosis of germ cells, there is a crucial difference from the mitosis of other cells in meiosis the two chromatids making up each chromosome remain together, so that whole chromosomes are separated from their homologous partners cell division then occurs, followed by a second division that resembles.

Read and learn for free about the following article: mitosis and meiosis. Mitosis what is mitosis mitosis is the division of a eukaryotic cell's nucleus leading to cytokinesis, which ultimately results in two identical cells (called daughter cells) the mitotic phase is short part of the overall cell cycle – which contains interphase as a quick review, interphase has 3 phases: g1, s and g2 – during these. Mitosis results in formation of two daughter cells genetically identical to the mother cell the number of chromosomes remains the same (unlike meiosis where the chromosome number is halved) mitosis occurs in both the haploid cells (eg fungi, plant gametophytes and animals like bees) and diploid cells for the growth.
