B) pipelines of the xylem
C) a mutually beneficial association between a fungus and a young root
D) structures on roots that house nitrogen-fixing bacteria
E) pipelines of the phloem
F) evaporation from stems and leaves
G) actively transport sucrose into sieve tube members
H) theory of sugar movement through phloem
Pressure Flow Theory
A model explaining how sugars are transported in plants, suggesting that sugars move from sources, where they are produced, to sinks, where they are used or stored, through the phloem via pressure gradients.
Nitrogen-Fixing Bacteria
Bacteria that convert atmospheric nitrogen into ammonia, a form accessible to plants for nutrition.
