Mitosis vs. Meiosis A little bit of review… Mitosis is cell division, producing 2 new cells that are identical to the parent Mitosis is an example of asexual reproduction, where there is just ____ parent!

Mitosis v.Meiosis In other words, you are taking a diploid cell and creating two more diploid cells Diploid: Cells that have pairs of similar chromosomes – body cells. Body Cells: Cells that are found throughout your body. Ex. If the parent cell has 10 chromosomes, then it goes through mitosis, how many chromosomes will be in the ‘daughter’ cells? ________

Mitosis vs. Meiosis Now….Meiosis! Meiosis is the process of cell division, where haploid cells (sex cells) are produced Haploid: cells that do not have chromosome pairs – they have half the number of chromosomes. Sex Cells: Cells that contain half of an organism’s DNA – sperm and egg cells.

Answer these questions… How many steps are in meiosis? In meiosis, you start with _____ cell and end with _____ cells. In meiosis, you start with a ________ cell and end with a ___________ cell

Meiosis So for example…. If a cell has 10 chromosomes and it goes through meiosis, how many chromosomes will be present in the new cells? _______

Meiosis and Fertilization Now, when two sex cells join together (fertilization), you have a diploid cell – the first cell of that new organism!

Review So what are some differences between mitosis and meiosis? Mitosis Meiosis
