Grade 4 science quiz: Parts and functions of plant stems

🌿 Quick Study Guide

• 🌱 Stems provide support for the plant, holding up the leaves and flowers.
• 💧 Stems transport water and nutrients from the roots to the rest of the plant through xylem.
• 🍎 Stems transport food (sugar) produced in the leaves to other parts of the plant through phloem.
• 🧱 Stems can be herbaceous (soft and green) or woody (hard and rigid).
• 🌳 Some stems, like potato tubers, can store food for the plant.
• ☀️ Stems help to position the leaves to receive maximum sunlight for photosynthesis.
• 🌵 Some stems, like those of cacti, can store water.
