With Jordan R. and Daniela L. Vocabulary/Key Terms: Eukaryotic: organisms that are composed of cells with organelles on the inside. Heterotrophs: organisms that obtains its necessary amounts of carbon from other organisms by consuming them, whether dead or alive. Parasites Feed off host Live in/on body Can cause infectious disease Specialized anatomically and physiologically Example: Tapeworms absorb nutrients through skin in small intestine. Can also cause infectious disease CHALLENGE: Name this parasite! + Sadly, they aren’t this cute: Fungi Eukaryotic Heterotrophs Multi-cellular Reproduce both sexually and asexually (good when environment is changing) Attack tissues of living plants and animals Competitors for food (attack food sources) Cause severe allergic reactions through mold spores (budding) CHALLENGE: 1- Guess who lived here Review Parasites Fungi Review Vocabulary/Key Terms: Natural Selection: Process in which species that have adapted will survive and continue to reproduce (unlike species that couldn’t adapt). Vocabulary/Key Terms: Characteristic Change: when an organism’s physical characteristics change over time (Ex.) If one bird has a short beak and is unable to grab food but then mates with a bird with a longer beak, their offspring might have a longer beak. Vocabulary/Key Terms: Phenotypes: an organism’s physical characteristics. Phenotypes influence many things, including: Find, obtain and use resources Ability to reproduce Variation in Traits Variations exist within each organism’s phenotype in every species. Natural selection plays a key part, especially when the environment is changing. If a species has favorable characteristics, they will most likely live. If a species doesn’t it will most likely end up dying out and going extinct. Always certain diversity among a species. The more diversity, the better! Review Variation in Traits Video He’s not… 0_o Are you ready for this? Test time! Instructions: Each team will come up with a nickname, but base it off of your material. Each team will receive a white board and will pick their Recorder to write down their answers. There are 20 questions on this test, a bonus question and 30 seconds to complete each question. Good luck! Question #1 Where do parasites mainly live? Answer: In or on their host Question #2 Define phenotypes and describe what they influence. Answer: they are an organism’s physical characteristics and they affect an organism’s ability to reproduce and find, obtain, and use resources Question #3 Are fungi eukaryotic or prokaryotic? Answer: Eukaryotic Question #4 + How do tapeworms obtain their essential nutrients? Answer: By absorbing them through their skin. Question #5 How do fungi cause disease? Answer: They attack tissues of living plants and animals. Question #6 How does the diversity among a species affect the repopulation of that species? Answer: if there is more diversity among the species, there will be a greater chance that they repopulate and continue to do so. Question #7 How do fungi repopulate asexually? Answer: They repopulate through budding. Question #8 Which picture best symbolizes a change in an organism’s characteristics? A: B: C: D: Question #9 Complete the analogy: Climate:_____:: fungi: disease Answer: Characteristic change Question #10 How do heterotrophs get their necessary amount of carbon? Answer: By consuming them, dead or alive. BONUS QUESTION!!! ARE YOU READY! (EXTRA CREDIT WORTH 5 POINTS) Here it is… Compare and contrast how the variation in phenotypes of parasites and fungi may benefit and harm them if the environment were to change. Congratulations!!!
