Question

Which of the following elements is not correctly matched : -

• A. Si - grasses (provides mechanical strength)
• B. Se - mesophytes (help in $C_3$ cycle)
• C. Na - halophytes (eg atriplex - help in $C_4$ pathway)
• D. Co - leguminous plants (root nodule formation)

Answer 1

Answer: (B)

Se - mesophytes (help in $C_3$ cycle)

• Silicon present in grasses provides mechanical strength.
• Sodium element in halophytes is essential for the C4 pathway.
• Cobalt present in leguminous plants helps in the root nodule formation.

So, the correct answer is 'Se - mesophytes (help in C3 cycle)'.
