Biology 102Lecture 19Outline of Last Lecture:I. Clicker QuestionsII. Plant EvolutionOutline of Current Lecture:I. Clicker QuestionsII. Plant Diversity III. FungiClicker QuestionsWhich combination of traits would you expect to in the female and male flowers of a WIND pollinated plant?a. Female: drab with no carpel; male: drab with small anthersb. Female: showy with small stigma; male: showy and heavily scented with small anthersc. Female: drab with large sticky stigmas; male: drab with few, small anthersd. Female: drab with large sticky stigmas; male: drab with many large anthersList examples of angiosperm/animal cooperation.1. Transfer pollen2. Fertilization3. Seed dispersal4. Nutrition5. Oxygen6. Shelter/protection7. All of the abovePlant Diversity There is a loss in plant diversity.- Most of this is due to land clearingo Once an area is cleared it ruins the habitat. Even if it is replanted the animals do not come back because they prefer a mature forest and do not come back for several years.Facts about plant diversity:- 50,000 square miles of forest are cleared every year- More than 25% of prescription drugs are extracted from plantsBiology 102FungiFungi can have symbiotic relationships with plants.- Can also have parasitic relationships: when one organism thrives from the other and in the process harms the other.o Ex. chestnut tree and chestnut blight: the chestnut blight is a fungus that grows on the inside and attacks the inside of the chestnut tree and as a result has destroyed a majority of the chestnut trees in the US.Fungi are heterotrophic eukaryotes-no modal: they don’t move they just grow in length towards a food source- The parts, individual parts, are called hyphae; the whole collection of hyphae is the mycellumo You can’t see the mycellum, the part of the fungi that you see is the reproductivestructure5 groups of fungi:1. Chytrids: flagellated spores, spores must swimo Likely evolved from an aquatic flagellated protistso Being blamed for the decline of frogs and amphibians, can decompose and be parasitic2. Zygote fungio The most recognizable fungi o Ex. bread moldo The fuzzy stuff is the reproductive part of the spore o Ex. penicillin: a type of bread mold 3. Arbuscular mycorrihizal fungi4. Sac fungi5.
