This engaging 250-word reading passage introduces fourth-grade students to the fundamental concept of plant structures and their functions, aligned with NGSS standard 4-LS1-1. Students discover that plants have both internal and external structures that serve various functions in growth, survival, behavior, and reproduction. The passage uses familiar plants and simple analogies to help students understand that every plant part has a specific purpose. Key vocabulary terms including structures, roots, stems, leaves, and xylem are bolded and defined in context. The content establishes the structure-function framework essential for deeper biological understanding. Audio integration supports diverse learners by providing text-to-speech functionality, making the content accessible to all students. The passage avoids dramatic hooks and instead focuses on clear, direct explanations that build foundational knowledge. Students explore how plant structures work together like organs in the human body, setting up important connections between form and function. Accompanying activities include multiple-choice questions testing recall and comprehension, writing prompts requiring explanation and application, and graphic organizers for documenting structure-function relationships. This comprehensive resource prepares students for hands-on investigations and class discussions about plant biology.
CONTENT PREVIEW

A structure is a part of a plant that has a specific job. Structures are the different pieces that make up a plant, like roots, stems, leaves, and flowers. Each structure helps the plant survive and grow. Understanding plant structures helps us see how plants meet their needs for water, nutrients, and sunlight.
Plants have external structures that we can see on the outside. The roots grow underground and take in water and nutrients from the soil. They also hold the plant in place. The stem supports the plant and carries water and nutrients from the roots to the leaves. The leaves use sunlight to make food for the plant. Flowers help plants make seeds so new plants can grow.
Plants also have internal structures that work inside the plant, just like organs work inside your body. Inside the stem are tiny tubes called xylem. These tubes carry water from the roots up to the leaves, like straws carrying water upward. Other tubes carry the food made in the leaves to all parts of the plant. All these structures work together as a system to keep the plant alive.
Every plant structure has a purpose. Without roots, a plant cannot get water. Without leaves, it cannot make food. Each part depends on the others to help the plant survive.
Interesting Fact: Some giant sequoia trees have roots that spread out over 100 feet underground, helping these massive trees stay standing for thousands of years!
What is a plant structure?
A part with a specific jobOnly the flower of a plantThe color of a plantThe smell of a plant
Where do roots grow?
On top of the leavesUnderground in the soilInside the flowerAbove the stem
What does xylem do?
Makes flowers colorfulHolds the plant uprightCarries water to the leavesProduces seeds
Why do plants need leaves?
To hold water undergroundTo make food using sunlightTo produce flowers onlyTo anchor in soil
How do stems help plants?
They make seeds for reproductionThey absorb sunlight for energyThey support and transport materialsThey take in soil nutrients
What happens if roots are removed?
The plant makes more foodThe plant cannot get waterThe leaves grow biggerThe flowers bloom faster
Plants have organs inside like humans do.
TrueFalse
What does 'external structures' mean?
Parts hidden inside the plantParts you can see outsideOnly the plant's rootsThe plant's food source
