Mitosis and meiosis of eukaryotic organisms
Figure 4a below shows how the two types of cell division, meiosis and mitosis, relate to the development of an organism that undergoes sexual reproductionfigure 4b shows what happens to the chromosomes during the processes shown in 4a note that the genomes of most eukaryotes are split between multiple distinct chromosomes. Eukaryotes, organisms whose cells contain complex structures within their membranes, experience either mitosis or meiosis all of these processes are a method of reproduction and dna replication these are called the daughter cells. Every cellular organism uses the process of cellular division in eukaryotes, the cell cycle is divided in interphase, where the cell readies itself for division, and mitosis, where the process of division occurs interphase takes up the majority of the cell cycle meiosis can sometimes occur instead of mitosis. There are two ways cell division can happen in humans and most other animals, called mitosis and meiosis mitosis is the cell cycle process by which chromosomes in a cell nucleus are separated into two identical sets of chromosome.
A closer look: mitosis is the process by which the nucleus divides in eukaryotic organisms, producing two new nuclei that are genetically identical to the nucleus of the parent cell diamf3 it occurs in cell division carried on by human somatic cells-the cells used for the maintenance and growth of the body these cells have two paired sets of 23 chromosomes, or 46 chromosomes in total. In mitosis, a cell divides and forms two identical daughter cells (prescott 102) each daughter cell then doubles in size and becomes capable of dividing most one-celled plants and animals reproduce by mitosis. Mitosis and meiosis are both forms of division of the nucleus in eukaryotic cells they share some similarities, but also exhibit distinct differences that lead to very different outcomes (figure 6) mitosis is a single nuclear division that results in two nuclei that are usually partitioned into two new cells.

Eukaryotic organisms carry out mitosis throughout their entire life to grow and to replace old or damaged cells some eukaryotic organisms use mitosis to meiosis ii: very similar to mitosis prophase ii: dna condenses into chromosomes no crossing over occurs. Eukaryotic organisms that sexually reproduce have a specialized set of cells that undergo meiosis rather than mitosis in meiosis, the parent cell splits into four daughter cells, or gametes, each of which has half as many chromosomes as the parent. Meiosis is the form of eukaryotic cell division that produces haploid sex cells or gametes (which contain a single copy of each chromosome) from diploid cells (which contain two copies of each chromosome) the process takes the form of one dna replication followed by two successive nuclear and cellular divisions (meiosis i and meiosis ii. The cell is the basic unit of all life all living things-- tigers, trees, elephants, and men-- are made up of cells a cell is alive-- as alive as you are it breathes, takes in food, and gets rid of waste it grows and reproduces, or creates one of i. Organisms which reproduce asexually cannot undergo meiosis, whereas all eukaryotic organisms undergo mitosis mitosis and meiosis are similar in that both can only occur in eukaryotic cells this is because prokaryotic cells do not contain a nucleus within which to begin the processes of mitosis and meiosis.
Unlike mitosis, meiosis is a sexual type of reproductionthis specific type of dividing cells is required for the sexual reproduction of eukaryotes in this process, the produced cells are called spores or gametes the cell has a couple of copies of each chromosome, one from the father and one from the mother. The cell cycle, mitosis and meiosis in some single-celled organisms mitosis forms the basis of asexual reproduction in diploid meiosis meiosis is the form of eukaryotic cell division that produces haploid sex cells or gametes (which contain a single copy of each chromosome). Meiosis is the process by which sexually reproducing organisms make their sex cells, sperm and eggs during meiosis, a specialized cell called a germ cell splits to make four new sex cells, each with half the number of chromosomes as the original germ cell. Mitosis results in growthduring mitosis a cell becomes two genetically, the two daughter-cells are identical to each other and to the original cell in single-celled organisms the daughter-cells separate.
Mitosis and meiosis of eukaryotic organisms
Eukaryotic organisms like humans, dogs, birds, insects, and other higher organisms rely on both to survive now, generally, mitosis and meiosis are similar in a sense the result of both divisions are daughter cells and the same sequence of events occurs in both. Meiosis is a special type of cell division that takes place only in cells involved in sexual reproduction in higher organisms like humans, these are immature sperm cells in males and developing eggs in females. Mitosis occurs in the cell nuclei of eukaryotic cells that are not related to reproduction, while meiosis takes place in the cell nuclei of eukaryotic cells that are related to reproduction cells not associated with reproduction are called somatic cells, and cells associated with reproduction are known as gamete cells. Eukaryotes are capable of two types of cell division: mitosis and meiosis mitosis allows for cells to produce identical copies of themselves, which means the genetic material is duplicated from.

- Mendelian genetics in eukaryotic life cycles the answer is that all haploid organisms that undergo meiosis create a temporary diploid stage that provides the meiocytes in some cases, such as in yeast, simplified representation of mitosis and meiosis at the dna level.
Mitosis and meiosis of eukaryotic organisms mitosis and meiosis of eukaryotic organisms 1101 words jan 25th, 2008 5 pages the cell is the basic unit of all life all living things-- tigers, trees, elephants, and men-- are made up of cells a cell is alive-- as alive as you are it breathes, takes in food, and gets rid of waste. 9 in the nucleus of eukaryotic cells, the distribution process occurs in the form of 2 different types of cell division mitosis is a conservative propagation of genetic information: the daughter cells have the same genetic composition as the. Meiosis - used by eukaryotic organisms to create sex cells (gametes) binary fission - used by prokaryotic organisms to reproduce despite their differences, remember that all three types of cell division begin with dna replication - the act of doubling the amount of dna in the cell.
