Q. Consider the following statements and choose the correct answer from the options given below I. A dry live seed still contains water II. A mature maize plant absorbs about 3 L water per day III. A mustard plant take up water equal to its weight in about five hours IV. Water is not considered as the limiting factor for plant growth and productivity
A) I, II, III and IV
B) IV and II
C) I, II and III
D) Only IV
Explanation
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 absorb about 3 L 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
