The correct Answer is:
To determine the correct statements among the provided options, we will analyze each statement one by one. ### Step-by-Step Solution: 1. **Statement I: Aerial roots are chlorophyllous and assimilatory in Vanda and Taeniophyllum.** - **Analysis:** Vanda and Taeniophyllum are epiphytic plants, meaning they grow on other plants and do not have a well-developed root system for anchoring in soil. Their aerial roots are modified to absorb moisture and nutrients from the air and their host plants, but they do not perform photosynthesis as they lack chlorophyll. Therefore, this statement is **incorrect**. 2. **Statement II: Two types of adventitious roots are found in sugarcane and maize.** - **Analysis:** Sugarcane and maize have a fibrous root system, which includes two types of adventitious roots: the main adventitious roots and stilt roots that provide additional support. This statement is **correct**. 3. **Statement III: Tap root and lateral roots possess nodules in bean and pea.** - **Analysis:** Bean and pea plants are part of the leguminous family (Fabaceae) and are known for forming nodules on their roots, which house nitrogen-fixing bacteria (e.g., Rhizobium). This statement is **correct**. 4. **Statement IV: Tap root and aerial adventitious roots are present in banyan and Chrysanthemum.** - **Analysis:** The banyan tree has a tap root system and aerial adventitious roots (prop roots) that provide support. However, Chrysanthemum does not have aerial adventitious roots; instead, it propagates through stem modifications (like rhizomes). Therefore, this statement is **incorrect**. ### Conclusion: The correct statements are: - Statement II: True - Statement III: True Thus, the final answer is that the correct statements are **II and III**. ---
