Plant Adaptations to Living in Wet Places
What is an adaptation? A trait that allows organisms to survive
their environment. Examples?
What stresses does living in the wet places put on plants? Unstable soil Salt (if it is brackish or salt water) No oxygen to the roots
Why no oxygen to the roots? Bacteria in the soil use oxygen Water keeps air from reaching the soil,
so the used up oxygen does not get replaced.
Foldable 8 tabs 4 per side
Outside=name of the adaptation Inside=picture/description of the
adaptation Inside=how it helps the plant survive
Aerenchyma Enlarged holes in
the stem Allows oxygen to
be transported down to the roots
Buttressing Flared out base of
the trunk Provides stability Increases surface
area to allow for more oxygen to be brought into the plant
Fluting Folds in the base
of the trunk Increases surface
area for increased gas exchange
Pneumatophores aka knees Extra trunks Increased surface
area for increased gas exchange
Adventitious roots Above ground
roots Allows for more
oxygen intake
Hypertrophied lenticels Enlarged openings
in the trunk Allows more
oxygen to come in
Floating leaves Leaves float (duh) Allows for gas
exchange Better for
photosynthesis
Salt glands Excrete salt from
plants Maintains
homeostasis
Seen in a lot of saltwater marsh plants such as Spartina alterniflora
