Correct Answer: C
Solution :
[c] A dry alive seed contains around 10-15% water of its weight. Water is a major component of life which is generally absorbed by plants in variable quantity according to their metabolic requirement. A mature maize plant absorbs about 3 litres of water/day, while a mustard plant can absorb the water equal to its weight in only 5 hrs. Hence, water is considered the limiting factor for plant life, growth and development.
