Options

A. Cypsela
B. Siliqua
C. Caryopsis
D. Samara

Answer

To solve the question about identifying a semi-dry, one-seeded fruit with the pericarp fused with the seed coat and forming from a monocarpellary gynoecium, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Gynoecium**:
- The gynoecium is the female reproductive part of a flower, which consists of one or more carpels. A monocarpellary gynoecium means there is only one carpel present.

**Hint**: Remember that the term "mono" indicates singularity.

2. **Identifying the Characteristics**:
- The fruit in question is described as "semi-dry" and "one-seeded". This indicates that the fruit has a dry texture and contains only one seed.

**Hint**: Focus on the texture and seed count of the fruit.

3. **Understanding Pericarp and Seed Coat**:
- The pericarp is the part of the fruit formed from the ovary wall and consists of three layers: epicarp, mesocarp, and endocarp. The seed coat is the protective layer surrounding the seed. The question specifies that the pericarp is fused with the seed coat.

**Hint**: Consider how the pericarp interacts with the seed coat in different types of fruits.

4. **Evaluating Fruit Types**:
- We need to consider the options given: Gipsella, Siliqua, Caryopsis, and Samara.
- Gipsella and Siliqua are types of fruits where the pericarp is not fused with the seed coat.
- Samara is a winged fruit and does not fit the description of being one-seeded with a fused pericarp.

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

5. **Identifying the Correct Fruit**:
- The only fruit type among the options that is semi-dry, one-seeded, and has a pericarp fused with the seed coat is **Caryopsis**. This fruit type is commonly found in grasses and belongs to the family Poaceae.

**Hint**: Recall that Caryopsis is a unique fruit type where the seed coat and pericarp are fused together.

### Final Answer:
The answer is **Caryopsis**.
