📚 What's the Difference Between a Seed and a Sprout?
Understanding the difference between a seed and a sprout is fundamental to grasping plant growth. A seed is a plant embryo waiting for the right conditions to germinate, while a sprout is what happens when that seed starts to grow.
🌱 Seed: The Dormant Beginning

📦 Definition: A seed is essentially a plant embryo encased in a protective outer covering called the seed coat.  It contains stored food (endosperm or cotyledons) to nourish the embryo during germination.
    😴 Dormancy: Seeds are often in a dormant state, meaning they are not actively growing. They require specific conditions like moisture, temperature, and sometimes light to break dormancy.
    🧬 Components: A seed consists of three main parts:
        
            👶 The embryo (the future plant)
             🍎 The endosperm (food supply for the embryo)
            🛡️ The seed coat (protective outer layer)

🌍 Purpose: The primary function of a seed is to ensure the survival and dispersal of the plant species.

🌿 Sprout: The Active Growth Phase

💧 Definition: A sprout is the young plant that emerges from the seed after germination. It shows visible signs of growth, such as a root and a shoot.
    ☀️ Germination: Germination is the process by which a seed begins to grow into a sprout. This requires the seed to absorb water, which activates enzymes that break down the stored food.
    🌱 Visible Parts: A sprout typically has the following visible parts:
        
             根 A radicle (the embryonic root)
             ⬆️ A plumule (the embryonic shoot)
              🍃 Cotyledons (seed leaves, which may or may not emerge)

📈 Growth: Sprouts are actively growing and require nutrients, water, and sunlight to continue developing into mature plants.
