examples of plants that grow from seeds

📚 Quick Study Guide

🔍 Seed Germination: The process where a seed develops into a plant. 💧 Key Factors: Water, oxygen, and suitable temperature are crucial for germination. 🌻 Seed Structure: Includes the embryo, endosperm (food source), and seed coat (protection). 🪴 Monocots vs. Dicots: Monocots have one cotyledon (seed leaf), dicots have two. 🌍 Common Examples: Many fruits, vegetables, and flowers originate from seeds. ⏱️ Germination Time: Varies greatly depending on the plant species; some germinate in days, others in weeks or months. 💡 Seed Dispersal: Methods include wind, water, animals, and even explosion!
