In Trapa some of the roots are

Options

A. Aerial
B. Assimilatory
C. Respiratory
D. Floating

Answer

To answer the question "In Trapa, some of the roots are," we will analyze the characteristics of the roots in the Trapa plant, which is an aquatic plant. Here’s a step-by-step solution:

### Step 1: Identify the Plant Type
Trapa is an aquatic plant, which means it grows in water bodies.

**Hint:** Consider the habitat of the plant when determining the characteristics of its roots.

### Step 2: Understand Root Functions
Roots in plants can serve various functions including anchoring the plant, absorbing water and nutrients, and in some cases, performing photosynthesis.

**Hint:** Think about how aquatic plants might adapt their roots for survival in water.

### Step 3: Analyze the Options
1. **Aerial Roots**: These roots are typically found in plants that grow above ground and are not characteristic of Trapa.
2. **Assimilatory Roots**: These roots can perform photosynthesis, which is a function that Trapa roots can do.
3. **Respiratory Roots**: These are specialized roots for gas exchange, which are not present in Trapa.
4. **Floating Roots**: While Trapa does have floating structures, the question specifically asks about roots.

**Hint:** Eliminate options that do not match the characteristics of Trapa.

### Step 4: Conclusion
Based on the analysis, the correct answer is that in Trapa, some of the roots are **Assimilatory** roots, as they can perform photosynthesis.

**Final Answer:** The correct option is **Assimilatory (Option 2)**.
