Seeds and Their Basic Parts
What you'll learn
- Identify basic seed parts: seed coat, embryo, and stored food.
- Explain why seeds are important for new plants.
- Differentiate healthy and damaged seeds in simple observation.
- Relate seed variety to Indian crops and fruits.
Key concepts
Level 1 - What is a seed?
A seed is the starting stage of many plants. It contains a tiny baby plant and food reserve.
Level 2 - Main parts
Seed coat protects inner parts. Embryo grows into new plant. Cotyledons often store food for early growth.
Level 3 - Seed diversity
Seeds differ in size, shape, and color: mustard is tiny, mango seed is large, bean seed is medium and easy to observe.
Level 4 - Indian context
Farmers in India select healthy seeds for crops like wheat, paddy, and pulses. Mango, guava, and papaya seeds from fruits can be used in school gardening projects. Better seed quality improves germination and crop yield.

Worked example
Bean seed observation
Step 1 - Soak bean seeds overnight.
Step 2 - Remove seed coat gently.
Step 3 - Open seed to view inner parts.
Step 4 - Identify cotyledons and tiny embryo.
Answer: Seed has protective coat and living embryo.
Healthy seed selection
Step 1 - Compare shriveled and plump seeds.
Step 2 - Check for damage or fungal spots.
Step 3 - Keep healthy plump seeds for sowing.
Step 4 - Discard damaged seeds.
Answer: Healthy seeds improve germination success.
Common mistakes
| Mistake | Why it happens | Fix |
|---|---|---|
| Seed is non-living | No movement seen | Seed is living but dormant |
| All seeds are identical inside | Outer look assumed same | Seed structure and food storage vary |
| Only big seeds can grow plants | Size linked to viability | Small seeds can also germinate |
| Fruit and seed are same | Part-whole confusion | Seed is inside fruit in many plants |
Quick check
- Name two basic parts of a seed.
- Why is seed coat important?
- Is mustard seed living or non-living?
- Give one example of a large seed.
- Stretch: Collect five edible seeds from kitchen and classify by size and likely food reserve amount.
Revision tip: A seed is a packed plant starter kit: protection, baby plant, and food.
