Plant Form and Function
Soil and Plant NutritionPlant biology, perhaps the oldest branch of science, is driven by a combination of curiosity and needcuriosity about how plants work need to apply this knowledge judiciously to feed, clothe, and house a burgeoning human population.
Plant Nutrition What does a plant
need to survive?• 9 macronutrients (required
in large quantities)• C, H, N, O, P, S, K, Ca, Mg• 8 micronutrients (required
in small quantities)• Fe, Cl, Cu, Mn, Zn, Mo, B, Ni
• Mycorrhizae symbiotic associations of fungi and roots mutualistic relationship Ectomycorrhizae - mycelium forms mantle over root Endomycorrhizae - does not form mantle; hyphae extend
inward• Parasitic plants
plants that supplement their nutrition from host mistletoe, dodder plant, Indian pipe
• Carnivorous plants supplement nutrition by digesting animals
