Real-World Examples of Roots, Stems, and Leaves in Action

📚 Quick Study Guide

• 🌱 Roots: Anchor the plant, absorb water and nutrients. Think carrots and radishes!
• 🪵 Stems: Provide support, transport water and nutrients between roots and leaves. Examples include tree trunks and celery stalks.
• 🍃 Leaves: Main site of photosynthesis, where plants make their food. Common examples are spinach leaves and lettuce.
• 💧 Absorption in Roots: Water moves from the soil into the root cells via osmosis.
• ☀️ Photosynthesis in Leaves: $6CO_2 + 6H_2O \xrightarrow{\text{light}} C_6H_{12}O_6 + 6O_2$
• ⬆️ Xylem (in stems): Transports water and minerals upwards from roots to leaves.
• ⬇️ Phloem (in stems): Transports sugars (food) produced during photosynthesis from leaves to other parts of the plant.
