solanaceae-alkaloids
2. Any trait that can be measured or recorded(i.e. and observable trait,color,
size, behavior, amount of chemical, flowering time, ect) - ANSWER ✔
phenotype
3. Important products from Brassicaceae: - ANSWER ✔ brocolli, cabbage,
Boc Choy
4. Which two families have similar floral formulas?: - ANSWER ✔ Solanaceae
and Asteraceae
5. Most of California's food exports are: - ANSWER ✔ plant products
6. Examples of fermentation: - ANSWER ✔ beer, digestion of cellulose
materials by cattle, wine, real yogurt -all of the above
,7. Genera that are close relatives of the genus Citrus, such as Fortunella
(kumquat) and Microcitru (Australian finger lime) are in which family?: -
ANSWER ✔ Rutaceae
8. Which of the following is true of the grass family? - ANSWER ✔ major
source of bio fuel, human food, one of the ten largest plant families, covers a
large fraction, (20%) of the Earth's land surface
-they are NOT a member of the Eudicot families
9. What is incomplete dominance? - ANSWER ✔ When the heterozygous
plants have an intermediate phenotype
10.What does intermediate phenotype mean? - ANSWER ✔ The phenotype is
unlike either parent
11.What is High Fe (HFE)? - ANSWER ✔ the Hemochromatosis Type 1 gene
12.What is a complex trait? - ANSWER ✔ Traits that are highly influenced by
the environment, ex: polygenic traits
13.Is a complex trait the same as a polygenic trait? - ANSWER ✔ Yes,
polygenic traits are controlled by more than one gene
14.What does G x E = P mean? - ANSWER ✔ Genes 'by' Environment equal
Phenotype
15.G + E = P - ANSWER ✔ Phenotype results from a combination of
environmental effects and genetic effects
,16.What is the G, E and P for asparagus urine smell? - ANSWER ✔ G is the
olfactory receptor 2 - wild-type alleles (OR2) vs mutant alleles(or2), E is the
act of eating asparagus, and P is that OR2 can perceive the S compounds of
the asparagus and or2 cannot perceive the S compounds
17.What is the E factor that changes the color of hydrangea flowers? Is there a
G component? - ANSWER ✔ The E factor is pH of the soil, the G
component is "same genotype"
18.How is hemochromatosis related to food? - ANSWER ✔ A homozygous
person can develop hemochromatosis if they consume an iron-rich(Fe) diet
19.What three crops were the focus of the Green Revolution? - ANSWER ✔
Greains (cereals): Wheat, corn, rice
20.There are four elements that increased crop productivity in the Green
Revolution. What are they? - ANSWER ✔ Nitrogen, Phosphorous,
Potassium, Oxygen
21.Why did growers focus on high-yielding, semi-dwarf plants? - ANSWER ✔
Were needed to support high fruit yields when grown with new agricultural
practices ; helped avert famines
22.What is lodging? - ANSWER ✔ Plant collapse when plants are top-heavy
23.Who is the father of the Green Revolution? What honor did he receive? -
ANSWER ✔ Norman Borlaug received the Nobel Peace Prize for his
inventions
, 24.What is shuttle breeding? - ANSWER ✔ accelerated breeding programs;
growing plantain 2 places (in Mexico) depending on season
25.Did the new varieties impact yields? - ANSWER ✔ Yes, yields (4x)
26.How did the new variety plants impact humanity? - ANSWER ✔ Averted
mass famines
27.What disadvantage to agriculture did these new high-yielding crops have? -
ANSWER ✔ Dependent on fertilizer
28.Where do plants get C, H and O needed for macromolecule biosynthesis? -
ANSWER ✔ From CO2 and H2O, and via photosynthesis
29.Why does a plant need nitrogen? - ANSWER ✔ Chlorophyll, amino acids
30.Where do plants get N? - ANSWER ✔ Nitrogen cycle (atmospheric N2
fixed by nitrogen , decaying organic matter)
31.How has the Green Revolution (GR) altered the nitrogen cycle? - ANSWER
✔ Nitrates lead to contaminated water and run-off
32.Why did we begin to make synthetic fertilizers? What are they made from? -
ANSWER ✔ There was a shortage of fixed nitrogen, Haber-Bosch process
used N2 AND HW atmosphere to make ammonia (NH3). Used to make
nitrate and nitrites
