Question 3 of 13intermediate🔧 ApplyShort Answer3 marks

You have learnt that different conditions are required for seed germination. How can we use this knowledge for proper storage of grains and pulses?

Correct Answer

For proper storage of grains and pulses, we should prevent the conditions that favour seed germination.

Seeds require water, air and suitable temperature for germination.

Therefore, grains and pulses should be stored in dry conditions with minimal moisture content.

They should be kept in airtight containers to prevent air and moisture from reaching them.

Storage areas should be cool and well-ventilated to prevent heat build-up.

Adding neem leaves or other natural preservatives can help prevent pest infestation.

The storage containers should be kept away from direct sunlight and checked regularly for any signs of moisture or pest attack.

Explanation

The chapter explains in Activity 10.2 that germination of bean seeds requires the right amount of water and air (Page 8). Seeds require water for germination as water softens the seed coat and helps the embryo develop. Seeds also need air for germination, using the air available in spaces between soil particles. Most seeds do not require light for germination, but after germination, sunlight is required for further growth. By eliminating or minimizing these conditions - especially water and air - we can prevent germination and ensure proper storage of grains and pulses.

Solution Steps

  1. Prevent conditions that favour seed germination for proper storage

  2. Seeds require water, air and suitable temperature for germination
