For this assignment, you will create a model of asexual reproduction and a model of sexual reproduction. To show the similarities, assume that both models represent a eukaryotic organism, or cells with nuclei. You will then answer a few questions on the Student Worksheet to help you compare the two and evaluate similarities and differences. Your final activity will be to write an essay that describes why asexual reproduction results in offspring that are identical to the original and why sexual reproduction results in diverse and unique offspring. Background Information Living things reproduce in two ways. Some reproduce by creating identical copies of themselves. This is known as asexual reproduction. Budding, fragmentation, and binary fission are types of asexual reproduction. Examples of organisms that reproduce asexually are hydra, bacteria, and planaria. Other living things reproduce by joining male and female sex cells. This is called sexual reproduction. Sexual reproduction allows for genetic differences between organisms of the same species. Examples of organisms that reproduce sexually are angiosperms, dogs, and humans. These two methods of reproduction involve a process in which the DNA is replicated and the cell divides. For asexual reproduction, it is mitosis in eukaryotes; for prokaryotes, the method is similar to mitosis, but without a nucleus. Sexual reproduction requires meiosis to create the sex cells. In both mitosis and meiosis, before a cell can divide, the cell must grow in size and the DNA must be replicated. This phase is called interphase. After cell division, whether it be mitosis or meiosis, the cytoplasm of the cell splits as two new cells are formed. This is called cytokinesis. All the steps of the life of a cell, from interphase through cytokinesis, are referred to as the cell cycle. Mitosis and meiosis differ in the number of divisions that happen, the number of resulting cells produced, and how the resulting cells compare to the original cells. Materials One piece of poster board Four markers or colored pencils; two colors of your choice as well as a brown and a blue Assignment Instructions Step 1: Prepare for the project. a) Read steps 2 through 8 so you know what you are expected to do during this project. If there is anything that is not clear to you, ask your teacher. Step 2: Gather materials for the model. a) See your teacher or proceed to the designated location to retrieve your piece of poster board and at least fo
