A specialised structure for asexual reproduction in liverworts is

Options

A. Gemmae
B. Zoospores
C. Sporangia
D. Microspores.

Answer

### Step-by-Step Solution:

1. **Understanding Liverworts**: Liverworts are a type of bryophyte, which are non-vascular plants that thrive in moist environments. They are often referred to as the amphibians of the plant kingdom because they require water for fertilization.

2. **Reproduction in Liverworts**: Liverworts can reproduce both sexually and asexually. Asexual reproduction is particularly important for their propagation.

3. **Specialized Structures for Asexual Reproduction**: In liverworts, asexual reproduction occurs through specialized structures known as **Gemmae**.

4. **Characteristics of Gemmae**:
- Gemmae are **green** and **multicellular**.
- They are produced asexually, meaning they do not involve the sexual reproductive cycle.
- Gemmae develop in small, cup-like structures called **Gemmae cups**.

5. **Location of Gemmae**: These Gemmae cups are found on the main body of the liverwort, known as the **thallus**.

6. **Examples of Liverworts**: Common examples of liverworts that utilize Gemmae for asexual reproduction include **Marchantia** and **Riccia**.

7. **Conclusion**: Therefore, the specialized structure for asexual reproduction in liverworts is **Gemmae**.
