Study Notes
What is Plant Adaptation?
- Adaptation is a process by which an organism or species becomes better suited to its environment.
- Adaptations often develop in response to a change in the organism's habitat.
Plant Adaptations in Different Environments
Desert Plants
- Desert plants like the thorny cactus and Joshua tree have:
- Small or no leaves to conserve water
- Many spines to conserve water
- Thick wax coat on leaves to retain water
- Leafless plants like cacti store water in their green stem
- Roots near the soil surface to soak up water before it evaporates
Tropical Rainforest Plants
- Plants in the tropical rainforest have:
- Drip tips and waxy coverings on leaves to shed extra water
- Prop roots to support them in shallow soil
- Grow on top of one another to reach sunlight
- Examples of plants: Bromeliads and lianas
Temperate Forest Plants
- Plants in the temperate forest have:
- Thick barks to shed them against chilly winters
- Broad leaves that capture a lot of sunlight
- Deciduous trees drop their leaves in autumn to minimize water loss
- Examples of plants: Wildflowers, oak, ash, maple, etc.
Aquatic Plants
- Aquatic plants have:
- Greener leaves on the upper side and red on the lower portion
- No stems as they do not require water to be absorbed
- Examples of plants: Water lily and lotus
Fun Facts
- The roots of the mesquite can be up to 50 to 80 meters long, the longest among desert plants.
- Grasslands are also known as prairies and have deep roots to survive prairie fires.

Plant Adaptations in Different Environments
Desert Plants
- Have small or no leaves to conserve water
- Have many spines to conserve water
- Have a thick wax coat on leaves to retain water
- Are leafless, storing water in their green stems (e.g., cactus)
- Have roots near the soil surface to soak up water before it evaporates (e.g., Joshua tree)
Tropical Rainforest Plants
- Have drip tips and waxy coverings on leaves to shed extra water
- Have prop roots to support them in shallow soil
- Grow on top of one another to reach sunlight (e.g., Bromeliads and lianas)
Temperate Forest Plants
- Have thick barks to protect against chilly winters
- Have broad leaves that capture a lot of sunlight
- Are deciduous, dropping leaves in autumn to minimize water loss (e.g., wildflowers, oak, ash, maple)
Aquatic Plants
- Have greener leaves on the upper side and red on the lower portion
- Do not have stems, as they do not require water to be absorbed (e.g., water lily and lotus)
