Choose the incorrect match.

Options

A. Cycas - Coralloid roots
B. Pinus - Needle like leaves
C. Ginkgo - Heterosporous
D. Cedrus - Embryo sac

Answer

To solve the question of choosing the incorrect match, we will analyze each of the given pairs step by step.

1. **Cyclus - Coralloid Roots**:
- Cyclus, a type of cycad, is known for having coralloid roots. These roots form a symbiotic relationship with nitrogen-fixing bacteria, which is essential for the plant's nutrition.
- **Conclusion**: This match is correct.

2. **Pinus - Needle-like Leaves**:
- Pinus, commonly known as pine trees, have needle-like leaves. These adaptations help them survive in cold climates by reducing water loss.
- **Conclusion**: This match is correct.

3. **Zingo - Heterosporous**:
- Zingo (likely referring to Ginkgo) is indeed a gymnosperm and is heterosporous, meaning it produces two types of spores: microspores and megaspores.
- **Conclusion**: This match is correct.

4. **Cedrus - Embryo Sac**:
- Cedrus (cedar trees) do not produce flowers; instead, they reproduce using cones. Since they do not have flowers, they do not have an embryo sac, which is part of the female reproductive structure in flowering plants (angiosperms).
- **Conclusion**: This match is incorrect.

### Final Answer:
The incorrect match is **Cedrus - Embryo Sac**.
