How does the property of water pictured above help a plant to thrive?
A. The like charges of the water molecules repel and force the water
up through the xylem.
B. The two water molecules form an oxygen bond, allowing for
photosynthesis to be accelerated.
C. The opposite charges of the water molecules attract and allow the
leaves to absorb water during precipitation.
D. The two water molecules form a hydrogen bond, allowing for
capillary action to draw the water up through the xylem.

Notes
Carbon is “special” because it’s 4 unpaired
electrons allow it to form covalent bonds
aka it wants to bond with/attach to other things!
3 structure types:
Straight Chain
Branched Chain
Ring
Notes
Monomer: small molecule, single unit in
larger molecule
Mono=one

POLYMERS
Notes
Polymer: large molecule, made out of
monomers bonded together
