Cell division: mitosis and meiosis how do eukaryotic cells divide to produce genetically identical cells or to produce gametes with half the normal dna align with the enduring understandings and learning objectives from the ap biology curriculum framework, as indicated below. Designed to match traditional ap® biology lab 3 using prepared slides and electronic images of whitefish and onion cells, students learn about the stages of mitosis and meiosis the 8-station kit includes enough materials for a class of 32 students working in groups of 4 the 1-station kit incl. Wwwnjctlorg psi ap biology cell cycle 9 metaphase is the stage of mitosis during which the chromosomes line up along the metaphase plate in preparation of separating into two cells.
Mitosis and meiosis share many procedural similarities, however, it is important to remember that mitosis makes identical cells while meiosis allows genetic variability between cells meiosis takes place in sex cells, which are capable of creating millions of different variations of offspring. Ap bio lab 3: mitosis and meiosis part a: mitosis background: it was discovered in 1858, by rudolf virchow, that new cells can only arise from previously existing cells this is done in two ways: mitosis and meiosis somatic (body) cells divide exclusively by mitosis followed by cytokinesis, while germ cells produce gametes by the process of. - [voiceover] before we go in-depth on meiosis, i want to do a very high level overview comparing mitosis to meiosis so, in mitosis, this is all a review, if you've watched the mitosis video, in mitosis, we start with a cell, that has a diploid number of chromosomes. A human cell ordinarily will have 23 pairs of chromosomes, for a total of 46 chromosomes at the end of a cell cycle, including mitosis, the new cells will have.

The lettered circle in the figure above shows a diploid nucleus with four chromosomes there are two pairs of homologous chromosomes, one long and the other short. In some respects, meiosis is very similar to the process of mitosis, yet it is also fundamentally different from mitosis the two stages of meiosis are meiosis i and meiosis ii at the end of the meiotic process, four daughter cells are produced. Her writing is featured in kaplan ap biology 2016 updated march 24, 2017 meiosis quiz meiosis is a two-part cell division process in organisms that sexually reproduce in some respects, it is very similar to the process of mitosis meiosis is divided into two parts: meiosis i and meiosis ii.

Meiosis is the term given to any cell division that results in four daughter cells being produced with exactly half the number of chromosomes as the parent cell.
Ibhl/ap biology year 2: test mitosis-meiosis - august 2009 -key 1 which phases of mitosis are shown in diagrams i and ii i ii i ii a metaphase prophase b metaphase telophase c anaphase prophase d anaphase metaphase 2 a cell with a diploid number of 12 chromosomes undergoes meiosis. Mitosis conserves the # of chromosome sets, producing cells that are genetically identical to the parent meiosis reduces the number of chromosomes sets from two (diploid) to one (haploid) producing cells that differ genetically from each other and from the parent cell. Mitosis produces two identical daughter cells and meiosis produces up to four different cells synapsis and crossing over do not take place in mitosis, but do in meiosis compare mitosis and meiosis with respect to each of the following. Compare the events and outcome of meiosis with mitosis explain the process and function of crossing over explain how various aspects of meiosis and sexual reproduction increases variation in a species.
