Dry indehiscent single-seeded fruit formed from bicarpellary syncarpous inferior ovary is

Options

A. caryopsis
B. cypsela
C. berry
D. cremocarp

Explanation

To solve the question regarding the dry indehiscent single-seeded fruit formed from a bicarpellary syncarpous inferior ovary, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Bicarpellary**: This indicates that the flower has two carpels.
- **Syncarpous**: This means that the carpels are fused together.
- **Inferior Ovary**: This refers to an ovary that is located below the other floral parts, indicating an epigynous flower.

2. **Identify the Fruit Type**:
- We are looking for a fruit that is **dry**, **indehiscent**, and **single-seeded**.
- Indehiscent fruits do not split open at maturity to release seeds.

3. **Recognize the Characteristics of Mericarp**:
- The indehiscent, single-seeded fruit type that arises from a bicarpellary syncarpous inferior ovary is known as a **mericarp**.

4. **Determine the Specific Fruit**:
- The specific type of mericarp formed from a bicarpellary syncarpous inferior ovary is called a **cremocarp**.
- Examples of plants that produce cremocarps include **fennel** and **coriander**.

5. **Eliminate Incorrect Options**:
- **Caryopsis**: This is a type of fruit where the pericarp is fused with the seed coat, typically from a monocarpillary pistil (e.g., grains like wheat, oats, rice).
- **Cypsela**: This is a type of achene that develops from an inferior ovary but is not the correct answer here.
- **Berry**: This is a fleshy fruit, which does not fit the description of being dry and indehiscent.

6. **Final Answer**:
- Based on the analysis, the correct answer to the question is **cremocarp**.
