Germination is defined as the process of conversion of seed into sprout . This process is dependent on various abiotic factors. This can be shown by the following activity:

  1. Take some dry moong seeds . Soak some of them and keep some dry.
  2. Let them soak for a day.
  3. Do not disturb the dry seed and divide these soaked seeds into 4 parts.
  4. Let the first part be completely submerged in water for 3-4 days.
  5. Keep the second part in sunlight, third in a completely dark place and the last part in very cold surroundings (eg. refrigerator).
  6. Let these seeds grow and change the water everyday.

 

It will be observed that all these sets show different germination patterns . It is slow in some and some may even die due to lack of proper abiotic factors.

Therefore, abiotic factors are very important for growth of plants and animals.
