Grade 7 Science Unit: 11 Lesson: 01 Asexual Reproduction in Living Organisms Station 1 Use the Internet, textbook, and/or other reference material to identify the domains and kingdoms of living organisms. Complete the Part 1 chart on your handout. ©2012, TESCCC 06/07/13 page 1 of 3 Grade 7 Science Unit: 11 Lesson: 01 Asexual Reproduction in Living Organisms Station 2 Read the following table: Organism Type of Asexual Reproduction Description Bacteria Fission Bacteria are unicellular prokaryotes that reproduce by splitting into two new cells. Spider plant Vegetative propagation 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”. Cyanobacteria Fission Cyanobacteria is a unicellular prokaryote that reproduces by splitting into two new cells. Protists Fission Protists are unicellular, eukaryotic organisms that reproduce by splitting in two. Hydra Budding Hydra reproduces through cell division to form a bud that is an identical copy of its single parent. The bud eventually separates from the parent and becomes independent. Strawberries Vegetative propagation Strawberries reproduce from runners or roots. Strawberries also reproduce sexually. Fungi Spores Mold and mushrooms asexually produce spores, which are packets of cells that leave the parent and grow in a new location. Answer the questions on your handout. ©2012, TESCCC 06/07/13 page 2 of 3 Grade 7 Science Unit: 11 Lesson: 01 Asexual Reproduction in Living Organisms Station 3 Materials: • microscope • prepared yeast (in Petri dish) • microscope slide • cover slip • toothpick • water • paper towels Procedure: 1. Smear a sample of yeast on a microscope slide with a toothpick. 2. Cover with a cover slip. 3. Use the microscope to focus properly on high power. 4. Record illustrations of the yeast budding. 5. Rinse the slide and cover slip. Dry thoroughly. ©2012, TESCCC 06/07/13 page 3 of 3
