Gas Transport in the Blood. Describe in detail how carbon
dioxide is transported in the blood. Be sure to include all the
ways the blood transports carbon dioxide and a detailed
explanation/description of how carbon dioxide is “loaded” and
“unloaded” from the blood both in the tissues and the alveoli.

c. Water moves from the xylem into the sieve tubes
d. Water moves from phloem into the xylem.
e. Solution in sieve tubes becomes hypertonic
f. Solution in sieve tubes becomes hypotonic.
g. Tugor pressure decreases

Briefly describe how materials are hypothesized to move
within the phloem of a plant, including the name of the hypothesis,
the structures and processes involved, and the direction of
flow.
