Specialized asexual structures in some liverworts are `:`

Options

A. Multicellular with ability to produce single daughter plant
B. Green, multicellular that given two daughter plants
C. Formed on lower or ventral surface in large receptacle
D. Developed in member is monoecious always

Answer

**Step-by-Step Solution:**

1. **Understanding Liverworts**: Liverworts are non-vascular plants belonging to the division Marchantiophyta. They reproduce both sexually and asexually.

2. **Asexual Reproduction in Liverworts**: In liverworts, asexual reproduction occurs through specialized structures that can develop into new individuals without the need for seeds or spores.

3. **Identifying Specialized Asexual Structures**: The specialized asexual structures in some liverworts are known as **gemmae**.

4. **Characteristics of Gemmae**:
- **Multicellular**: Gemmae are made up of multiple cells.
- **Green in Color**: They typically have a green coloration due to the presence of chlorophyll.
- **Production in Gemma Cups**: Gemmae are produced in cup-like structures called **gemma cups**, which are located on the dorsal side of the thallus (the main body of the liverwort).

5. **Detachment and Growth**: Once gemmae are mature, they detach from the parent plant and can grow into new liverworts, effectively allowing for asexual reproduction.

6. **Conclusion**: Based on the characteristics and functions of gemmae, the correct answer to the question about specialized asexual structures in some liverworts is that they are **green multicellular structures that give rise to daughter plants**.

**Final Answer**: The specialized asexual structures in some liverworts are **green multicellular structures that give rise to daughter plants**.
