PLANT STRUCTURES
What do roots do for a plant?
Absorb water and anchor the plant
What do gills help fish do?
Breathe underwater
Name one Utah environment
Desert, forest, wetland
What happened to the wilted plant after water was added?
It stood back up
What is a solution?
A way to solve a problem
Why do some plants have thorns?
To protect from animals
Why do ducks have webbed feet?
To swim
Which environment has the most water?
Wetland
What structure helps pine cones open and close?
Scales
What should a good design include?
Structures that meet needs
What structure helps plants make food?
Leaves
Why do mammals have lungs instead of gills?
They breathe air
Why do desert animals have special structures?
To survive heat and lack of water
Why do pine cones close when wet?
To protect seeds
Why do we test designs?
To see if they work
A plant has thick, waxy leaves. What environment might it live in?
Dry/desert
Compare a dolphin and a fish—what structure is different and why?
Dolphin has lungs (breathes air), fish has gills (water)
What structure might a forest animal have? Why?
Camouflage fur—to blend in
Why can fish breathe underwater but dolphins cannot?
Different breathing structures
What are constraints?
Limits (materials, time, environment)
Explain how internal structures help a plant “come back to life” after water is added.
Water moves through internal tubes (xylem), restoring structure and function
How do body structures help animals survive in different environments?
Structures are adapted for getting food, protection, and survival in specific environments
Explain why the same plant could not survive in all Utah environments.
Different environments require different structures (water, temperature, soil)
What do all these phenomena show about structures?
Structures directly affect survival and function
Design a plant for the desert—what structures would it need?
Thick stem, small leaves/spines, deep roots
