This engaging 250-word reading passage helps Grade 4 students understand the internal structure of seeds, aligned with NGSS standard 4-LS1-1. Students discover that seeds are survival packages containing three essential parts: the embryo (baby plant), stored food that nourishes the growing plant, and a protective seed coat. The passage explains how these parts work together during germination when conditions like water, warmth, and soil are right. Written at a fourth-grade reading level, the passage uses clear explanations and relatable examples to build foundational understanding of plant structures and their functions. The lesson includes audio integration for accessibility, a simplified differentiated version for struggling readers, Spanish translations of both versions, a comprehensive glossary of key terms, multiple-choice questions testing recall and comprehension, writing activities requiring application of concepts, and graphic organizers for visual learning. Students explore vocabulary terms including seed, embryo, stored food, seed coat, and germination. This complete educational resource supports diverse learners while maintaining rigorous alignment to Next Generation Science Standards for elementary life science.

Inside a plant's tiny survival package.
A seed is a tiny survival package that holds everything needed to grow a new plant. Seeds help plants spread to new places and survive through seasons when growing conditions are difficult.
Inside every seed are three important parts. The first part is the embryo, which is the baby plant waiting to grow. The embryo has the beginnings of roots, a stem, and leaves all folded up in a very small space. The second part is stored food, which surrounds the embryo like a lunch box packed with energy. This stored food gives the baby plant the nutrients it needs to start growing before it can make its own food through its leaves. The third part is the seed coat, which is the tough outer covering that protects the embryo and stored food from damage, insects, and drying out.
When conditions are just right—with enough water, warmth, and soil—the seed begins a process called germination. The seed coat softens and splits open. The embryo uses the stored food for energy to push roots down into the soil and a stem up toward the sunlight. Think of it like a packed suitcase that contains everything a traveler needs for a journey. The seed is packed with everything the baby plant needs to begin its life.
Interesting Fact: Some seeds can survive for hundreds of years! Scientists successfully grew a plant from a 2,000-year-old seed found in an ancient palace.
