Open in App
Solution
Aim: To prove that a suitable temperature is necessary for germination.
Materials Required:
1. Beakers (2)
2. Cotton wool (wet)
3. Refrigerator
Procedure:
- Label two beakers A and B
- In each of the beakers, place a few gram seeds on wet cotton wool.
- Place beaker A at ordinary room temperature and beaker B in the refrigerator.
Observations:
- On day one or two, the seeds in beaker A germinate showing the importance of suitable temperature for germination.
- No signs of germination are observed in beaker B, they may germinate in a few days, though not as much as that in beaker A.
- Hence, we can conclude that for the germination of seeds, temperature plays a key role. A suitable temperature is required for seed germination.
