Question 3 (Page 204) You have learnt that different conditions are required for seed germination. How can we use this knowledge for proper storage of grains and pulses?We have learnt that Seeds need water, air, and Sunlight to germinate. So, for proper storage of grains and pulses, We do not want seeds to germinate So these conditions are avoided by drying the grains,(Prevent Water) storing them in airtight containers(Prevent Air) and keeping them in cool and dry places.(No Sunlight) Detailed AnswerKeep grains dry Moisture triggers germination. Grains and pulses are sun-dried before storage. Stored in dry places away from rain and humidity. Result: No water → no germination Detailed AnswerStore in airtight containers Airtight containers reduce oxygen availability. Common methods: Metal bins, Airtight plastic containers or Sealed gunny bags with inner lining Result: Limited air → germination slows or stops Detailed AnswerStore in cool conditions High temperature speeds up germination and spoilage. Large storage warehouses use temperature control. Result: Unsuitable temperature → germination prevented
