Food storage bodies in green algae

Options

A. Are found freely in the cytoplasm
B. Contain protein besides monosaccharides and lipid
C. Are located in the chloroplasts
D. Are membrane bound structures with protein and starch

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the food storage bodies in green algae. We need to identify the characteristics and locations of these storage bodies.

2. **Identifying the Food Storage Bodies**: In green algae, the primary food storage bodies are known as pyrenoids.

3. **Characteristics of Pyrenoids**:
- **Location**: Pyrenoids are located within the chloroplasts of green algae.
- **Composition**: They primarily store starch, which is a polysaccharide, and do not contain membrane-bound structures.
- **Structure**: Pyrenoids are non-membrane bound organelles, meaning they lack a surrounding membrane.

4. **Analyzing the Options**:
- The first option states that they are found freely in the cytoplasm, which is incorrect as they are located in chloroplasts.
- The second option mentions they contain protein besides monosaccharides and lipids. While they may contain some proteins, their primary storage is starch, not monosaccharides.
- The third option correctly states that they are located in the chloroplast, which aligns with our understanding of pyrenoids.
- The fourth option describes them as membrane-bound structures with protein and starch, which is incorrect since pyrenoids are non-membrane bound.

5. **Conclusion**: The correct answer is that food storage bodies in green algae (pyrenoids) are located in the chloroplast.

**Final Answer**: They are located in the chloroplast.
