mitosis and meiosis in a plant cell or an animal cell. The relative duration of each stage in the cell cycle will also be learned during this lab. By doing this lab we will also create a model of and understand the process of crossing over. This lab also helps students understand the similarities along with differences between mitosis and meiosis. Purpose The objectives of the lab were to help give us a better understanding of cell cycles and divisions. Methods/Procedure 5.2 Meiosis: First we

Objectives Upon completion of this laboratory you will be able to: 1. list the similarities and differences between mitosis and meiosis. 2. describe and recognize the stages of mitosis under a microscope or on models. 3. know the events that occur during each stage of mitosis and meiosis. 4. define the boldface terms.

Meiotic Mysteries By: Karen Schindler In class we went over the cycle of meiosis‚ the sexual life cycle‚ and its stages. Meiosis has four stages which are‚ prophase I‚ metaphase I‚ anaphase I‚ and telophase I. In an adult before ovulation the oocyte goes back to meiosis forming a meiotic spindle of microtubules to segregate homologous chromosomes. When it reaches fertilization‚ the egg itself undergoes a second round of division segregating sister chromatids. Which is Prophase II‚ Metaphase II

experiment. These stages are prophase‚ metaphase‚ anaphase and telophase. There are two types of nuclear division include mitosis and meiosis. Mitotic cell division is involved in the formation of an adult organism from a fertilized egg‚ asexual reproduction‚ regeneration‚ and maintenance or repair of body parts. Mitosis typically results in new somatic‚ or body cells. Meiosis results in the formation of either gametes in animals or spores in plants. The cells formed have half the chromosome number of the

W4Q1 Meiosis is the process by which cells divide and create living creatures. Without meiosis we cannot have the process of mitosis‚ which is the process by which cells of tissue are created for living creatures. When meiosis occurs 4 daughter cells are created‚ while only 2 are created in mitosis. With the creation of 2 daughter cells the new cells will be similar to the parent cell‚ but will have differences‚ as there more parent cells involved. When mitosis occurs the daughter cells will be

Biology homework 10.2 1. How are the cells at the end of meiosis different from the cells at the beginning of meiosis? Use the terms chromosome number‚ haploid‚ and diploid in your answer. A: Cells in the begining of meiosis has diploid cells‚ with a full amount of chromosomes. In the end of meisos‚ the four genetically different daughter cells are haploid (gametes)‚ they have half the number of chromosomes. Because of this‚ they are able to fuse with other gametes (ex. egg and sperm) to form

microtubule structure that brings about chromosomal movement during nuclear division. 3. Compare Meiosis I to Meiosis II. Do they end up with the same exact results? Why or why not? Both Meiosis I and Meiosis II have four steps‚ but in Meiosis II it is a repeat of everything but instead of chromosomes sister chromatids are formed. No they do not end up with the same exact results‚ because during Meiosis II is the duplication stage basically. 4. What do the terms synapsis and crossing over mean
