Plant and animal
adaptations to climate
– For plants precipitation is generally
the limiting factor in determining
whether a climate is a desert, forest
or grassland, but biomes are not
uniform. They have the same
general characteristics but there are
microclimates that determine the
actual plants you will find in any
given area.
Plants exposed to cold year
around or in the winter
have:
•
•
Traits that keep them from losing
too much heat or water
They stay small
Desert plants must be able
to lose heat and conserve
water. They do this by:
•
•
Lose heat and store water
Fleshy tissue, vertical, no
leaves, store water
In wet tropical climates the
plants have
• Broadleaf evergreen, maximize
sunlight
In climates that are hot in
summer and cold in winter,
plants have:
• Deciduous leaves that fall off in
winter
In areas with cool short
summers, the trees have:
•
•
Coniferous evergreen
Needle shaped leaves
