The correct Answer is:
To answer the question "Chlorophyllous, autotrophic aerial roots are seen in," we can follow these steps: ### Step 1: Understand the Terms - **Chlorophyllous**: This refers to roots that contain chlorophyll, which is the pigment necessary for photosynthesis. - **Autotrophic**: This means that the organism can synthesize its own food from simple inorganic substances, primarily through the process of photosynthesis. - **Aerial Roots**: These are roots that grow above the ground and are often exposed to air. ### Step 2: Analyze the Options We have four options to consider: - A. Venda - B. Regis - C. Cascata - D. Tenuophyllum ### Step 3: Identify the Characteristics We need to find which of these options has roots that are: 1. Chlorophyllous (contain chlorophyll) 2. Autotrophic (can perform photosynthesis) 3. Aerial (growing above ground) ### Step 4: Evaluate Each Option - **Venda**: Not known for chlorophyllous aerial roots. - **Regis**: Also does not typically have these types of roots. - **Cascata**: Similar to the previous two, it does not fit the criteria. - **Tenuophyllum**: This plant belongs to the Orchid family, has short stems, and possesses flat, green, photosynthetic roots that are aerial. ### Step 5: Conclusion Based on the analysis, the correct answer is: **D.
