Answer

To determine which characters belong to Laminaria, we will analyze each character provided in the question step by step.

### Step-by-Step Solution:

1. **Floridean starch**: This is a characteristic of red algae (Rhodophyceae), not brown algae (Phaeophyceae) like Laminaria. Therefore, this character does not belong to Laminaria.

2. **Sulfated phycocolloids in cell wall**: Laminaria has a cell wall that is primarily cellulosic and does not contain sulfated phycocolloids. Instead, it has a gelatinous coating known as algin. Thus, this character does not belong to Laminaria.

3. **Alginic acid**: Laminaria does contain alginic acid, which is a component of its cell wall. This character belongs to Laminaria.

4. **Trumpet hypha**: Laminaria has trumpet hyphae, which are specialized conducting cells similar to sieve tubes in higher plants. This character belongs to Laminaria.

5. **Haplodiplontic life cycle**: Laminaria exhibits a haplodiplontic life cycle, where both haploid (gametophyte) and diploid (sporophyte) stages are present. This character belongs to Laminaria.

6. **Isomorphic alternation of generation**: Laminaria does not show isomorphic alternation of generations; instead, it exhibits heteromorphic alternation of generations. Therefore, this character does not belong to Laminaria.

7. **Fucoxanthin**: This pigment is characteristic of brown algae, including Laminaria. Therefore, this character belongs to Laminaria.

8. **Phycoerythrin**: This pigment is found in red algae, not in brown algae like Laminaria. Thus, this character does not belong to Laminaria.

9. **Zygotic meiosis**: Laminaria does not undergo zygotic meiosis; instead, it has a sporophytic stage. Therefore, this character does not belong to Laminaria.

10. **Two anterior flagella**: Laminaria does not have two anterior flagella. This character does not belong to Laminaria.

### Summary of Characters Belonging to Laminaria:
- C. Alginic acid
- D. Trumpet hypha
- E. Haplodiplontic life cycle
- G. Fucoxanthin

### Final Answer:
The characters that belong to Laminaria are C, D, E, and G.
