11 Ag Science Flashcards
.001, H+, pH 3. T/F?
True - .001
10-3 = pH 3 H+ Ions.
Ethylene
Ripening of fruit
Release of Dormancy
Stimulate shoot root growth
Stimulate leaf abscission
Cytokinins
Control major growth periods of the plant
Links to ethylene to control abscission flowers, leaves, fruits`
Stigma
Female part of plant
Top of pollen receptacle
Leads to ovary
Pistil
Female Collective parts of flower
Anther/Filament
Pollen Producers
Photosynthesis
6 CO2 + 6 H2 O ~> C6 H12 O6 + 6O2
Soil Structure
Percentage of Sand, Silt and Clay
Nitrogen
Macro - Involved in
Cell function division
Protein synthesis
Photosynthesis
Transfer of energy
Epigeal Germination
Cotyledons pushed above soil line provide energy until photosynthesis takes over

Gonadotrophin release controlled by hypothalamus
Name the key player in ruminant protein digestion
The rumen
Explain the differences in the anatomy of a monogastric to a ruminant
Monogastrics only have one compartment to their stomach, whereas ruminants have four compartments: rumen, reticulum, omasum, and abomasum.
NaHCo3
Sodium bicarbonate
What does The “Bomb Calorimeter” measure
The heat released or absorbed during a combustion reaction, expressed in quantities of calories or Joules
Calories/Kilojoules
1 calorie = 4.184 Kilojoules
multiply the energy value by 4.184
Protein Digestion
When protein is digested it is broken down into peptides ( Short chains of amino acids) Which then becomes NH4+ ( Ammonium cation)and NH3- (Ammonia)
Two Types of Protein
Crude and NPN
Crude Protein CP
Protein that needs to be broken down to a usable form
NPN
Non Protein Nitrogen
Rumen Microbes
Major Source of Protein in a bovines diet.
Breaks down CP and NPN to NH4+ and NH3-
