Unit 6: Plant Form and Function Plant Nutrition Review
  1. The branching system and system of plants obtain the nutrients of water, minerals, and dioxide from the environment. These molecules are made of .
  2. Nine of the elements are called since they are required in relatively large amounts; the remaining eight are known as , needed in small amounts mainly as of enzymes.
  3. Soil is composed of weathered of various sizes, along with decaying organic material called , arranged in vertical layers called .
  4. Soil particles are usually , and the film of water bound to soil is inaccessible to plants. Clay soils are and also bind charged minerals. Those minerals are made available to plants by exchange when plants release CO2 into the soil as a product of cellular .
    Review: How Plants Obtain Minerals from Soil
  5. Nitrogen- Rhizobium bacteria , in symbiosis with plants, convert inorganic N2 in the atmosphere to nitrogenous minerals such as and that plants can absorb.
  6. Most plants also form , a symbiotic association of fungi and roots which can be two types.
    • In , the mycelium of the fungus forms a dense sheath over the surface of the root.
    • In , fungal hyphae extend into the root, forming arbuscules.
  7. Unusual nutritional adaptations in plants include:
    • can nourish themselves, but grow on another plant. They absorb water and minerals from rain, mostly through rather than roots.
    • plants absorb sugars and minerals from their living hosts. Many species have roots that function as , nutrient-sbsorbing projections that enter the host plant.
    • plants are photosynthetic but obtain some and other minerals by digesting small animals.
