Multiple Choice

Green plants make their own food through a process called photosynthesis. How do the different plant parts work together in this process to support growth and survival?

• Leaves absorb sunlight and minerals from the air. Roots absorb water and use sunlight to make food.

• Leaves absorb carbon dioxide from the air and use sunlight to make food. Roots absorb water and nutrients from the soil.

• Leaves absorb oxygen and carbon dioxide from the air. Roots use sunlight to produce food.

• Leaves use sunlight to convert oxygen and nutrients into food. Roots absorb water and nutrients from the soil.

Multiple Choice

Which of the following best describes an adaptation in organisms?

• A learned behavior that helps an organism survive

• A physical or behavioral feature inherited from parents that improves survival

• A temporary change in behavior due to environment

• A structure that has no effect on survival

Fill in the Blanks

The arrangement of parts that benefit an organism, such as birds’ beaks or thorns on a cactus, is called

.

Multiple Select

Which of the following are examples of the function of a structure in an organism?

• A bird's beak cracking seeds

• A cactus having spines

• A mouth eating food

• A flower being colorful

Multiple Choice

Based on the sample student responses for the Big Bluestem Grass Station, what advantage do long roots provide to the plant?

• They help absorb water deep in the ground

• They protect the plant from animals

• They help the plant grow taller

• They make the plant look more attractive

Multiple Choice

How do spines help the prickly pear cactus survive, according to the student responses?

• They help the cactus absorb more water

• They make it harder for animals to eat and damage the cactus

• They help the cactus grow faster

• They attract pollinators

Open Ended

How do the structures of a plant help it survive in its environment?

Multiple Choice

Which of the following plants is most likely to have structures that store water?

• Big bluestem grass

• Prickly pear cactus

• Bladderwort

• Oak tree

Open Ended

Explain how the spines of the prickly pear cactus and the bladders of the bladderwort are examples of plant adaptations.

Multiple Choice

• 1) Plant roots, 2) Prickly pear cactus spines, 3) Bladders on bladderwort stems

• 1) Plant leaves, 2) Prickly pear cactus flowers, 3) Roots of big bluestem grass

• 1) Bladders on bladderwort, 2) Plant roots, 3) Prickly pear cactus spines

• 1) Prickly pear cactus spines, 2) Plant roots, 3) Bladders on bladderwort

Open Ended

What evidence did you collect during the investigations that helped you determine the function of each plant structure?

Multiple Choice

What is the main function of spines in the prickly pear cactus?

• Absorb water

• Capture animals

• Protect from predators

• Help in photosynthesis

Multiple Choice

Which plant structure is responsible for absorbing water from deep in the soil?

• Long roots

• Spines

• Bladders

• Leaves

Multiple Select

Which of the following are acquired traits in plants? Select all that apply.

• A plant growing taller due to more sunlight

• A cactus having spines

• A plant losing leaves after a storm

• A flower's color inherited from parent plants

Fill in the Blanks

Organisms receive

traits from their parents.

Open Ended

Choose one plant structure (such as roots, stems, leaves, or flowers). Describe how this structure helps a plant survive in its environment. Explain how this same structure might be different in a plant that lives in a very different environment. Give an example to support your answer.

The sharp spines of a cactus mainly protect it from

.

Open Ended

Explain how the structures of plants help them survive in their environment. Provide at least two examples from different types of plants.

Multiple Choice

Which of the following explains how the prickly pear cactus’ structure helps it survive in the desert, and how would this change if the cactus had no spines?

• The spines protect the plant from herbivores. Without the spines, the cactus would be more vulnerable to animals.

• The spines absorb nutrients from the soil. Without spines, the cactus would not get the nutrients it needs to survive.

• The spines help the cactus attract water from the air. Without them, the cactus would be unable to collect rainwater.

• The spines allow the cactus to grow taller quickly. Without spines, the cactus would grow slower and struggle to reach sunlight.

Open Ended

What is one new thing you learned about how plants make their own food and the role of different plant parts in this process?

Multiple Choice

How do the different plant parts work together in photosynthesis to support growth and survival?

• Leaves absorb sunlight and minerals from the air. Roots absorb water and use sunlight to make food.

• Leaves absorb carbon dioxide from the air and use sunlight to make food. Roots absorb water and nutrients from the soil.

• Leaves absorb oxygen and carbon dioxide from the air. Roots use sunlight to produce food.

• Leaves use sunlight to convert oxygen and nutrients into food. Roots absorb water and nutrients from the soil.
