Nutrients by Element
Name the essential non-mineral macronutrient that we supplement via out HVAC system.
Carbon
What is the difference between cations and anions?
Cations have positive charges and anions have negative charges.
What two elements are essential for the creation and integrity of cell walls?
Calcium and Boron
Name the three corners of the pest and disease triangle.
1. Susceptibility of Host
2. Pest/Disease Presence
3. Conducive Environment
True or False: Plants use noble gases for essential nutrients.
100 Bonus: Name a noble gas
False. None of the noble gasses are essential plant nutrition.
100 Bonus: Helium, Neon, Argon, Krypton, Xenon, Radon
Describe the major function of Calcium in the plants.
100 Bonus: Is it mobile or immobile?
100 Bonus: What micronutrient shares a similar function and supports it?
Calcium is used in a variety of functions, but the one most important to us is the creation and reinforcement of the cell walls, especially at the grow point of the plants.
100 Bonus: immobile
100 Bonus: Boron
What ion is being measured when we monitor pH?
100 Bonus: Is the pH scale linear or logarithmic?
hydrogen ions
100 Bonus: Logarithmic
Name the most numerous mineral nutrient in plant tissue by total volume.
100 Bonus: Is it mobile or immobile?
Nitrogen
100 Bonus: Mobile
Name 2 methods of mechanical (physical) management.
Mesh, doors, vents, airflow, walls, filters, physical barriers
Name the essential micronutrient that has the highest atomic number.
100 Bonus: What is that atomic number?
Molybdenum
100 Bonus: 42
What is the major function of iron within the plant in relation to chlorosis?
100 Bonus: Is iron mobile or immobile?
Iron is used to make heme proteins that are used in the creation of chlorophyll. If there is a deficiency of iron, no chlorophyll is made leading to chlorosis.
100 Bonus: Immobile
True or False: Does a fewer number of covalent bonds in an ion make it more or less difficult for the plant to uptake passively?
200 Bonus: What process do plants utilize for passive uptake of ions?
Ions with fewer bonds are easier for the plants to uptake.
100 Bonus: Osmosis
What essential macronutrient is responsible for chlorophyll formation?
100 Bonus: Is it mobile or immobile?
200 Bonus: What is the other essential macronutrient that is famously antagonistic with it?
Magnesium
100 Bonus: Mobile
200 Bonus: Calcium
Name 2 methods of chemical management
Pesticides, ozone, chlorination, oxygenation, acid or base washes
Name the essential nutrient with the lowest atomic number.
100 Bonus: What is the atomic number?
Boron
100 Bonus: 5
Name some of the functions of copper in plants.
100 Bonus: Is copper mobile or immobile?
Copper is used to make a variety of enzymes in the plant. Those enzymes catalyze lignin biosynthesis, transfer electrons during photosynthesis, and mediates nitrogen, protein, and carbohydrate metabolism in plants.
100 Bonus: immobile
True or false: As the pH decreases the ions with quad-valent bonds change to tri-valent bonds.
100 Bonus: Does that make those ions more or less available to the plant?
True. As the pH decreases phosphate ions (PO4+4), will turn into PO4+3, PO4+2, PO4+1, and eventually HPO4 (phosphoric acid)
100 Bonus: Each fewer covalent bond makes that ion more available to the plant
What essential macronutrient (one of the big 3), is used for the creation of ATP, phospholipid bilayers, oils/lipids, and DNA?
100 Bonus: Is it mobile or immobile?
Phosphorus
100 Bonus: Immobile
Name 2 biological management methods
beneficial insects, beneficial bacteria, beneficial fungus, bioinsecticides, plant growth promoters,
Name the two alkali earth metals that are essential for plant nutrition.
100 Bonus: Since they are so similar do you expect them to have a syngergistic or antagonist relationship?
Calcium and Magnesium
100: They are antagonistic
Name the function of molybdenum in plants.
100 Bonus: Is it mobile or immobile?
Molybdenum is used in the metabolism of ammonia in the plants as well as nitrate fixing.
100 Bonus: immobile
Would plants that have accumulated an excess of negatively charged potassium ions be more likely to passively more positively charged ions or negatively charged ions?
200 Bonus: Describe the charges of the two nitrogen ions that we provide our plants.
They would be more likely to passively uptake more positive ions. Opposites attract.
200 Bonus: Ammonia is positive NH4+ and Nitrate is negative NO3-
What essential macronutrient (one of the big three) is used to open and close the stomata via the guard cells?
100 Bonus: Is it mobile or immobile?
200 Bonus: What is another essential macronutrient that is used for osmotic regulation within the plant and in plant cells?
Potassium
100 Bonus: Mobile
200 Bonus: Chloride, Hydrogen. Sodium is sometimes used but is not an essential nutrient.
Name 2 cultural management methods
Sanitation, quality control, GMP, system maintenance, following SOP, trainings,
What is the only essential mineral micronutrient that is not a transition metal?
100 Bonus: Is it mobile or immobile?
Boron
100 Bonus: Immobile
