AngiospermsoVascular, flowering plantsoSeeds are encased in theovary of the plantoFruit is ripened ovaryExamples:DogwoodFringe TreeGrassesClover 6. NitrogenFixationPlants need nutrients fromnitrogen in the air. Grassescannot convert nitrogen tousable nitrate.Clover has bacteria in theroots that fix nitrogen tofertilize the plants around it. 7. GymnospermsGymno=naked Sperm=seedoVascular, seed-bearing plant.oSeeds are bare and contained in a cone.oExample: pine trees 8. The female pine cone is the large,woody looking cone you usuallythink of when you picture a cone. Itcontains the egg that is fertilized toform the seed.The male cone is smalland wormy looking. Itcontains the pollen thatfalls into the femalecone.Pine seeds 9. FernsoVascular (have veins)oNon-seed bearingoReproduce by SporesoSpores located on back ofleaves 10. Mosseso Non-vascularhave noveins to carry water andfoodo Grow close to the groundo Need moist, cool place togrowo Reproduce by spores 11. Why does Moss usually grow on thenorth side of a tree?In the Northern Hemisphere, the sun travels along a southern path in thesky, warming and drying the surfaces it touches. 12. Spore CapsuleOrange-yellow structure atthe end of stalk whichmosses put out thatcontain the spores.
