    2. Name species of plants associated with each center
  4. Identify plant communities (biomes).
    1. Name environmental characteristics of each biome
    2. Name species of plants associated with each biome
    3. Detail the features of the grassland/Central Iowa biome
  5. List the five critical environmental factors that when properly managed have the greatest influence on plant growth
  6. List the ten characteristics of a living organism
  7. Identify the seventeen chemical elements essential to plant growth
    1. Name the six macro nutrients/elements
    2. Name the three to four secondary nutrients/elements

  8. Identify plant cell anatomical features
  9. Describe the functions of plant cell anatomical features
  10. Explain the independent plant cell anatomical features functions as they relate to the function of the cell as a whole
  11. List the five phases of mitosis
    1. Identify what happens in each phase of mitosis
    2. Describe how the five critical environmental factors influence mitosis
    3. Identify where mitosis takes place within a plant
    4. Explain how mitosis ultimately influences the formation of plant tissues
  12. List the five plant hormones that influence mitosis and growth
    1. Identify the plant growth hormones that have a positive influence on plant growth
    2. Identify the plant growth hormones that have a negative influence on plant growth
  13. Identify essential plant tissues
    1. Describe the functions of simple permanent tissues
    2. Describe the functions of complex permanent tissues

  16. Explain transpiration (xylem) and phloem transport movements throughout roots, stems, and leaves.
  17. Explain tropism movements of leaves, stems and roots
  18. Identify the major phases in photosynthesis
    1. List the sequence of activities within the light phase of photosynthesis
    2. List the sequence of activities within the dark phase of photosynthesis
  19. Identify the major steps in plant respiration
