Statement 1: Plants cannot use atmospheric nitrogen directly.

Statement 2: Root nodules in the members of Dal family host rhizobium bacteria.

• A. Only statement 1 is correct.
• B. Only statement 2 is correct.
• C. Both the statements are correct.
• D. Both the statements are incorrect.

Answer 1

The correct option is C Both the statements are correct.

Plants cannot use atmospheric nitrogen directly. Hence, they convert it into other nitrogenous compounds which can be absorbed. The members of Dal family have root nodules that provide shelter to certain bacteria like rhizobium. These bacteria can convert atmospheric nitrogen into other forms of nitrogen.
