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 matches one by one.

1. **Cycus and Carolite Roots**:
- Cycus is a type of Gymnosperm, and it is known to have specialized roots called Carolite roots. These roots are associated with nitrogen-fixing cyanobacteria, which is beneficial for the plant. Thus, this match is **correct**.

2. **Pinus and Needle-like Leaves**:
- Pinus, also a Gymnosperm, is characterized by its needle-like leaves. These adaptations help reduce surface area and minimize water loss, especially in harsh environments. Therefore, this match is **correct**.

3. **Gingko and Heterosporous Plants**:
- Gingko is another example of a Gymnosperm and is indeed heterosporous, meaning it produces two different types of spores (microspores and megaspores). Hence, this match is also **correct**.

4. **Cedrus and Ambriosac**:
- The term "Ambriosac" refers to the female gametophyte in plants. However, the correct term for the female gametophyte in Gymnosperms is not "Ambriosac"; this term is specifically used for the female gametophyte in Angiosperms, which is called the embryo sac. Since Cedrus is a Gymnosperm, this match is **incorrect**.

Thus, the incorrect match is **Cedrus and Ambriosac**.

### Step-by-Step Solution:
1. Analyze the first match: Cycus and Carolite Roots - Correct.
2. Analyze the second match: Pinus and Needle-like Leaves - Correct.
3. Analyze the third match: Gingko and Heterosporous Plants - Correct.
4. Analyze the fourth match: Cedrus and Ambriosac - Incorrect (Ambriosac is for Angiosperms).

### Conclusion:
The incorrect match is **Cedrus and Ambriosac**.
