Genetically Modified Organism
what can causes nitrogen fixation?
lighting or combustion of fossil fuel
Bacteria that are nitrogen fixers (like in legumes)
Explain what causes plant roots to grow in the direction of gravity
Auxins inhibit growth in the root
name 4 types of manegment technices
cultural, chemical, biological, mechanical
What are the three primary nutrients?
Nitrogen, Phospherous, and Potassium (NPK)
What is an advantage to GMO Crops
Increase nutritional value, cheaper to mass produce, Cheaper cost
what does decomposers produce?
Ammonium

What is the process of turning N2 into nitrate?
Fixation
Give two ways that auxins are used by farmers
Weed Killers and Rooting powers
what is a limitation of biological mangement
timing
Symptoms of nutrient deficiencies (at least two)
Yellow or reddish leaves, stunted growth, and poor flowering.
Chlorosis, mottling, necrosis
What are 2 examples of disadvantages of GMO Crops
Crops have no seeds, Tradition of normal ways, spread of illness
What does fertilzer help with?
It goes to the Nitrates and helps with the growing procces

high cost rate
What is this picture showing?
Chlorosis
Whats used in the intecticide gene
DNA technology
How does the nitrogen cycle differ from the water cycle (besides the obvious that it is a different chemical)
Bacteria are a major player in the nitrogen cycle.
Which is responsible for inducing mitosis in root and stem cells
Cytokinins
What is an important part of knowing your IPM plan is working or not?
