• A. a-ii-4, b-iii-2, c-iv-3, d-i-1
• B. a-ii-4, b-i-2, c-iv-3, d-iii-1
• C. a-ii-4, b-i-2, c-iii-1, d-iv-3
• D. a-ii-3, b-i-1, c-iv-4, d-iii-2

Answer 1

The correct option is B a-ii-4, b-i-2, c-iv-3, d-iii-1

• Saprophytic plants grow on dead and decaying matter. E.g., Mold, fungi, yeast, etc.
• Parasitic plants grow on another plant (host) and have special roots called haustoria. They help in absorbing nutrients from the host plant. E.g., Cuscuta, loranthus, etc.
• Insectivorous plant grow on nitrogen deficient soil. To compensate for nitrogen deficiency they feed on insects. Their leaves are modified to trap insects. E.g., Utricularia, drosera, pitcher plant, etc.
• Pea plants are leguminous plant. They live in symbiotic association with certain bacteria (e.g. rhizobium). Bacteria lives in the root nodules of plant and fixes atmospheric nitrogen.
