Thick roots arising in Ficus to support heavy branches are called

Options

A. Stilt roots
B. Prop roots
C. Assimilatory roots
D. Floating roots

Answer

To answer the question regarding the thick roots arising in Ficus (banyan tree) that support heavy branches, we can follow these steps:

### Step 1: Identify the Plant
The question mentions "Ficus," which refers to the banyan tree. This tree is known for its extensive branching and large structure.

**Hint:** Remember that Ficus is commonly known as the banyan tree, which has a unique root system.

### Step 2: Understand the Function of the Roots
The roots in question are specifically designed to support the heavy branches of the banyan tree. This adaptation is crucial for the tree's stability and growth.

**Hint:** Think about why a tree would need additional support for its branches, especially when they are heavy and widespread.

### Step 3: Identify the Type of Roots
The roots that arise from the branches of the banyan tree and grow downwards into the soil are known as prop roots. These roots provide additional support to the tree.

**Hint:** Consider the term "prop" as it relates to providing support, similar to how props are used in construction or theater to hold something up.

### Step 4: Eliminate Other Options
The question provides other types of roots: stilt roots, assimilary roots, and floating roots.
- **Stilt roots** are found in maize and arise from the basal node of the stem.
- **Assimilary roots** are modified roots that perform photosynthesis and are found in orchids.
- **Floating roots** are found in aquatic plants like water lilies.

**Hint:** Compare the characteristics of the roots mentioned in the options with the description of the roots in the banyan tree.

### Conclusion
Based on the identification of the plant, the function of the roots, and the elimination of other options, the thick roots arising in Ficus to support heavy branches are called **prop roots**.

**Final Answer:** Prop roots
