Elementary science questions about seed sprouting.

📚 Quick Study Guide

• 🌱 Germination: This is the process where a seed starts to grow. It needs water, oxygen, and the right temperature.
• 💧 Water: Water softens the seed coat and activates enzymes inside the seed that start the growing process.
• 🌡️ Temperature: Different seeds like different temperatures to sprout. Some like it warm, some like it cool.
• ☀️ Sunlight: While sunlight isn't needed for germination *itself*, it's absolutely essential once the seedling emerges and begins photosynthesis.
• 🌍 Soil: Soil provides support and nutrients for the growing plant, but some seeds can even sprout without soil initially!
• 🧪 Seed Anatomy: Key parts include the seed coat (protection), endosperm (food source), and embryo (the baby plant).
• 📈 Stages of Germination: Imbibition (water absorption) → Radicle emergence (root) → Plumule emergence (shoot).
