Mrs.Keadle JH Science Name__________________________________ period _____ date assigned_____________ date due ______________ date returned _____________ Asexual Reproduction Section 1: Use the internet or other reference material to identify the domains and kingdoms of living organisms. In order to review the domains and kingdoms of living organisms, fill in the chart below. Leave the examples blank until you have done all four sections. Make sure you add the organisms from the chart on Section 4 to the examples. DOMAINS AND KINGDOMS Domain Domain Domain Kingdom Kingdom Kingdom Kingdom Kingdom Kingdom Examples Examples Examples Examples Examples Examples 1 Asexual Reproduction Mrs.Keadle JH Science Section 2: Using the internet, find and draw an example of a prokaryotic cell and a eukaryotic cell. For each one, label where the DNA or genetic material is found. prokaryotic cell eukaryotic cell Section 3: Use the prepared slide, or search a video on-line of yeast “budding”. Budding is a form of asexual reproduction so it only requires one parent. Draw and describe what you see in the space below. Budding Yeast 2 Asexual Reproduction Mrs.Keadle JH Science Station 4: Read through the following information about asexual reproduction and answer the questions that follow. Organism Type of Asexual Reproduction bacteria fission cyanobacteria fission protists fission spider plant vegetative propogation strawberries vegetative propogation hydra budding fungi spores Description Bacteria are unicellular prokaryotes that reproduce by splitting into new cells. Cyanobacteria is a unicellular prokaryote that reproduces by splitting into new cells. Protists are unicellular, eukaryotic organisms that reproduce by splitting into new cells. Spider plants produce new plants from roots or runners. The root or runner can be placed in water or soil to produce another plant. This process is sometimes referred to as “cuttings”. Strawberries reproduce from runners or roots. Strawberries can also reproduce sexually. Hydra reproduce by through cell division to form a bud that is an identical copy of its parent. The bud eventually separates from the parent and becomes independent. Mold and mushrooms form spores, which are packets of cells that leave the parent and grow in a new location. 22. What are the four types of asexual reproduction listed on the chart? 23. What do all of these types of asexual reproduction have in common? 24. How will the offspring compare to the parent in terms of traits and genetic material? 25. Can humans reproduce asexually? ______________________________________________ 3 Asexual Reproduction Mrs.Keadle 26 During asexual reproduction in paramecia, a single paramecium becomes two new paramecia. The genetic material of the new paramecium is usually A identical to the original B half the amount of the original C double the amount of the original D similar to the original 28 JH Science 27 To teach her class about different forms of reproduction and how they relate to diversity, Mrs. Griffin asked her students to draw a picture of a simple organism. They were then supposed to get tracing paper and trace the organism again. This process most closely represents A sexual reproduction B spontaneous generation C genetic mutation D asexual reproduction Strawberries can reproduce by means of runners, which are stems that grow horizontally along the ground. At the region where the runner touches the ground, a new plant develops. The new plant is genetically identical to the parent because F it was produced sexually G nuclei traveled to the new plant through the runner to fertilize it H it was produced asexually J there were no other strawberry plants in the area to provide fertilization 4 Asexual Reproduction
