Class VI Science Quiz: Seeds and Seeds

Part 1: Soaking and Sprouting (Page 42)

Part 9: Seed Dispersal (Page 8)

31. Have you ever heard the sound of soybean pods bursting?

Example: Yes, a popping or cracking sound (page 8).

32. What would happen if seeds did not spread and remained in one place?

They would compete for space, water, and sunlight, and most would not grow (page 8).

33. List three ways seeds are spread.

Wind, animals, bursting pods (page 8).

Part 10: Summary Questions (Page 9)

34. What do seeds need for sprouting? What would happen if they didn’t get these?

Water, air, warmth; without these, seeds would not sprout and remain dormant (page 2).

35. How do seeds spread to far-off places?

By wind (flying seeds), animals (sticking to fur), bursting pods, or humans carrying them (pages 7–8).
