Step-by-Step Solution

Verified
Answer
Haustorial roots are characteristic of parasitic plants.
1Step 1: Understanding the question
The exercise is direct and requires understanding of botanical concepts. Haustorial roots are roots which can penetrate the host plant's tissue to tap resources like water and nutrients. The feature of haustorial roots is commonly seen among parasitic plants.
2Step 2: Eliminate incorrect options
Epiphytes are plants that grow on other plants but do not utilize their resources. Nitrate fixers and leghemoglobin users refer to functions associated with nitrogen-fixing bacteria, not types of roots. Lastly, carnivorous plants often possess modified 'leaves' to trap insects, and do not rely on haustorial roots.
3Step 3: Confirm the correct answer
Given the nature of haustorial roots and the explanations given in Step 2, it is clear that haustorial roots are characteristic of parasites.
