A feature or behavior that helps an organism survive.
- 2. Multiple Choice
Which feature of a rose helps it grow without being eaten by large animals?flowers with bright colorssharp thornssmall seedsdeep roots - 3. Multiple Choice
Plants which require minimum moisture
Tropophytes
Xerophytes
Mesophytes
Hydrophytes
- 4. Multiple Choice
Plant leaves of different species have features that allow them to survive in their particular environment. It's reasonable to suggest that
hydrophyte leaves are small and thin to aid in floating and maximum photosynthesis.
water lilies have most stomata on the upper surface of their leaves for effective gaseous exchange.
leaves with sunken stomata are usually found in rain forests and wetlands.
hydrophyte leaves have a thick, waxy cuticle to prevent water loss.
- 5. Multiple ChoiceWhy might some plants that grow on the shady rain forest floor have large leaves?to stay safe from predatorsto attract different animalsto survive harsh winters with heavy snowfallto take in as much sunlight as possible
- 6. Multiple Choice
A plant adaptation commonly found in dry, hot climates is
a thin waxy cuticle
numerous small stomata
plants with stomata that open during the night
ability to lose leaves during the wettest part of the year
- 7. Multiple Choice
Desert plants have a shallow, fibrous root system because
The roots need to provide a larger surface area for water uptake
The roots need to reach water that may be found at relatively greater depths
The roots need to store more water so the plant can survive in arid conditions
The roots need to absorb as much water as possible, as quickly as possible, in the event of rain or fog occuring.
- 8. Multiple Choice
Two structures on a plant that work to reduce water loss include
Stomata
Roots
Waxy cuticle on leaves and stems
Stem
