Genetics Essential Questions 1. What should you now know? (Read and find out) Living things are made of smaller structures whose functions enable the organisms to survive. The basic unit of structure in all living things is the cell. Cells combine to form tissues that combine to form organs that combine to form systems that work together for the benefit of the entire organism. While most cells have common structures, there are differences between plant and animal cells. Cell details are usually visible only through a microscope. Reproduction passes genetic information from parent to offspring. Asexual reproduction requires one parent and produces nearly identical offspring. Sexual reproduction requires two parents, and provides variety in a species. This variety may allow the species to adapt to changes in the environment and help the species survive. A species may change due to the passing of inherited traits naturally or by techniques used and developed by science. Genetic information is passed on in a predictable manner. Not all traits are inherited, some are acquired (you learn or gain them instead of being born with them). Directions: The following essential question journal gives you the opportunity to reflect/review on what you know. It is made of only key points and questions. Each essential question will ask to recall something you should know or ask you to demonstrate how to do something 1: Compare how sexual and asexual reproduction passes genetic information from parent to offspring. A. Make a chart or a Venn diagram below to compare and contrast the two types of reproduction(asexual and sexual) and cite advantages/disadvantages to each? B. Make a chart or a Venn diagram below to compare and contrast the two types of cell division; Mitosis and Meiosis? C. What is a trait? D. What is the difference between inherited and acquired traits? Give an example of an inherited and acquired trait. E. Explain 2 methods of asexual reproduction and 3 methods sexual and name organisms that use each method. 2. Relate the adaptability of organisms in an environment to their inherited traits and structures. A. Give at least two examples of structural or behavioral adaptations that one organism has to help it in food getting, movement and protection. Name of organism? ______________________________ Food Getting 1. 2. Protection 1. 2. Movement 1. 2. B. Provide at least two examples of organisms with traits that may provide an advantage for survival in one environment but not other environments. C. Describe how the following structures or organs could help an organism be successful in its environment. A Birds Hollow Bones Hollow hair of some animals White fur on a polar bear Sharp teeth of a wild feline or canine Dense root structure of plants Fish Fins D. Complete the chart for each of the following terms that each has something to do with changes in genetic traits in living things.
