Plant AdaptationsPlant AdaptationsWhat does Adaptation mean?
The special characteristics that enable plants and animals to be successful in a
particular environment are called adaptations.
Adaptations help a plant to:
· Get Sunlight, Water, Air, or Nutrients
· Not be eaten
· Stay put
· Reproduce
Tropical Rainforest Bark: limits evaporation
Lianas: woody vines that climb to reach sunlight
Drip Tips: enable raindrops to reach roots
Buttresses, Prop and Stilt Roots: give support in shallow, wet soil
Bromeliads: leaves form a tank that holds water
Epiphytes: don’t require soil,
“air plants”
Carnivorous Plants
Plant Type AdaptationPlant Type Adaptation
Desert Roots: grow near the surface to collect rainwater quickly
Thick Stems: to store water
Leaves with hair: help shade the plant, reducing water loss.
Spines: to discourage animals from eating plants for water;
Waxy coating on stems and leaves: help reduce water loss.
Flowers that open at night: lure pollinators who are more likely to be active during the cooler night.
Slower growing: requires less energy. The plants don't have to make as much food and therefore do not lose as much water.

Deciduous Forest Deciduous Trees drop their leaves
Broad, thin, light-weight leaves: capture sunlight
Thick bark: protect against cold winters
Tundra Size:(usually less than 12 inches tall) and low-growing due to lack of nutrients, because being close to the ground helps keep the plants from freezing, and because the roots cannot penetrate the permafrost.
Plants are dark in color: some are even red—this helps them absorb solar heat.
Hair: helps keep them warm.
Grow in clumps: protect one another from the wind and cold.
Dish-like flowers: focusing more solar heat on the center of the flower, helping the plant stay warm.

Grassland Thick bark: resist fire
Roots: resprout after a fire
Roots: extend deep into the ground to absorb as much moisture as they can
Extensive root systems: prevent grazing animals from pulling roots out of the ground
Narrow leaves: which lose less water than broad leaves
Soft stems: enable prairie grasses to bend in the wind
Taiga Evergreen: so that plants can photosynthesize right away when temperatures rise
needle-like leaves: which shape loses less water and sheds snow more easily than broad leaves/ waxy coating prevents evaporation
Needles are dark in color: allowing more solar heat to be absorbed
Branches that droop downward: to help shed excess snow to keep the branches from breaking

In Water Underwater leaves and stems: flexible to move with water currents
Air spaces in their stems: to help hold the plant up in the water
Roots and root hairs: reduced or absent; roots only needed for anchorage, not for absorption of nutrients and water
Leaves that float atop the water: exposing themselves to the sunlight
Chlorophyll is restricted to upper surface of leaves (part that the sunlight will hit) and the upper surface is waxy to repel water
Produce seeds that can float
