**Step-by-Step Solution:**

1. **Understanding Algae**: Algae are a diverse group of photosynthetic organisms that are primarily aquatic. They contain chlorophyll and can perform photosynthesis.

2. **Analyzing the Options**:
- **Option A**: "Algae have root, stem and leaves." This statement is incorrect because algae do not have true roots, stems, or leaves. Their structure is not differentiated like higher plants.
- **Option B**: "Algae have true roots but lack leaves." This statement is also incorrect as algae do not possess true roots.
- **Option C**: "Algae have rhizoids and leaves." This statement is misleading because while some algae may have structures similar to rhizoids, they do not have true leaves.

3. **Conclusion**: After evaluating all the options, the correct statement about algae is that the body of algae is thallus (Option D).

**Final Answer**: The true statement for algae is: "Body of algae is thallus."
