PLNT 1213 Exam 2 study guide
Characteristics of a Monocot: - correct answer ✔✔-One cotyledon
-Hypogeal germination
-Below the surface
-Fibrous root system
-Linear leaves with parallel veins
Examples: grasses and lilies, corn, wheat, and rice.
Characteristics of a Dicot: - correct answer ✔✔-Two cotelydons
-Epigeal germination
-Above the soil
-"Fleshy"
-Leaves with netted venation
-Taproot system
Examples: broadleaved plants, soybean, cotton, and alfalfa
Hypogeal Emergence - correct answer ✔✔-Monocot
-Growth point (cotelydon) stay below the soil surface for a certain amount of time
Epigeal Emergence - correct answer ✔✔-Dicot
-Growth point (cotelydons) stay above the soil surface
A farmer is walking through the field and realizes that someone accidentally ran over the corn that had
emerged earlier that week. Should he be worried? - correct answer ✔✔No, because of hypogeal
emergence, it is below the surface.
, A farmer is walking through the field and realizes that some deer have eaten the leaves of the cotton
plants that had emerged earlier that week. Should he be worried? - correct answer ✔✔Yes, because of
epigeal emergence, it is above the surface.
Shoot - correct answer ✔✔-Above ground portion of the plant

Leaves - correct answer ✔✔-Flattened and expanded lateral growth from the stem
-Primary function: photosynthesis
-"solar panels"
Leaves role in photosynthesis - correct answer ✔✔-intercept light
-regulate gas exchange
- water vaper: OUT and CO2: IN.
