Plant and Animal Structures and Functions Worksheets for Grade 6 Science focus on how specialized structures and organ systems help organisms obtain resources, transport materials, grow, reproduce, and survive. This resource connects plant structures such as roots, stems, leaves, flowers, xylem, and phloem with the digestive, respiratory, and circulatory systems in animals.

🌱 Build Connections Between Structure and Function

Students examine how the function of each structure contributes to the needs of an organism. They identify how roots anchor plants and absorb water and minerals, how stems support plants and move materials, and how leaves capture light energy and exchange gases. The resource also distinguishes the roles of xylem and phloem, including the movement of water and minerals upward and the transport of sugars from leaves to other parts of the plant.

Animal systems are explored through their connected functions. Students identify how the digestive system breaks food into usable nutrients, how the respiratory system brings oxygen into the body and removes carbon dioxide, and how the circulatory system transports oxygen, nutrients, and other materials to cells. The emphasis on system interactions helps students connect individual structures with larger life processes.

What Students Practice

• Reading comprehension focused on plant structures, animal organ systems, and survival
• Multiple-choice questions about roots, xylem, leaves, phloem, and major organ systems
• True-or-false statements that reinforce structure-function relationships
• Short-answer explanations comparing xylem and phloem and connecting organ systems
• Matching, cloze reading, and an extended-response task requiring examples of resource acquisition, transport, and use
• A brief science fact section that extends the topic

📚 What the Teacher Receives

• ✅ Student worksheet covering the complete structures and functions topic
• ✅ Separate PDF answer key for checking student work
• ✅ Student Notes & Lesson Summary supplement for organizing key ideas
• ✅ Separate Teacher Guide with Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes

Classroom Use

This Grade 6 structures and functions science activity can support instruction in the Organisms and Environments lesson topic. The reading passage establishes the core concepts before students apply them through selected-response, written-response, and completion tasks. The extended response provides an opportunity to explain how plant structures and animal organ systems work together rather than treating each structure as an isolated fact.

For teachers using TEKS-aligned Grade 6 Science materials, the resource provides a focused way to address structures, functions, transport, and interactions within organisms while giving students multiple opportunities to use the topic vocabulary in context.
