In little club moss, embryo develops from the part of zygote and the rest is used to form suspensor. This mode of development is called

Options

A. Exoscopic
B. Endoscopic
C. Meroblastic
D. Holoblastic

Answer

To solve the question regarding the mode of development in little club moss where the embryo develops from part of the zygote and the rest forms the suspensor, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Organism**: Recognize that little club moss, also known as Lycopodium, belongs to the family Lycopodaceae. This information helps in understanding the context of the question.

**Hint**: Identify the organism and its classification to understand its developmental processes.

2. **Identify the Development Process**: The question states that the embryo develops from part of the zygote, while the remaining part forms the suspensor. This indicates a specific type of cleavage during the development.

**Hint**: Focus on the details of how the embryo and suspensor are formed from the zygote.

3. **Examine the Options**:
- **Exoscopic**: This refers to the shoot apical meristem growing outward from the gametophyte. Not relevant here.
- **Endoscopic**: This refers to the shoot apical meristem growing inward from the gametophyte. Not relevant here.
- **Meroblastic**: This refers to partial cleavage where only part of the zygote divides, which aligns with the embryo developing from part of the zygote.
- **Holoblastic**: This refers to complete cleavage where the entire zygote divides into separate cells, which does not apply here.

**Hint**: Analyze each option based on the definitions and see which one matches the description given in the question.

4. **Select the Correct Answer**: Since the embryo in little club moss develops from part of the zygote and the rest forms the suspensor, this mode of development is called **meroblastic**.

**Hint**: Choose the option that describes partial cleavage, as it matches the development process described.

### Final Answer:
The mode of development in little club moss where the embryo develops from part of the zygote and the rest forms the suspensor is called **meroblastic**.
