The nucleus of Spirogyra cell lies

Options

A. Suspended in central vacuole
B. Embedded in cytoplasm
C. Just near the cell membrane
D. In contact with the chloroplast.

Answer

To answer the question about the location of the nucleus in a Spirogyra cell, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organism**: Recognize that Spirogyra is a green filamentous freshwater alga that belongs to the division Chlorophyta. This information is essential as it provides context about the organism's characteristics.

2. **Understand the Cell Structure**: Familiarize yourself with the general structure of Spirogyra cells. Notably, they have a unique feature - spirally coiled, ribbon-like chloroplasts.

3. **Locate the Nucleus**: The question specifically asks about the nucleus. In Spirogyra, the nucleus is not freely floating in the cytoplasm but is instead located in a specific position within the cell.

4. **Identify the Correct Location**: According to the information, the nucleus of a Spirogyra cell is suspended in a central vacuole. This is a distinctive feature of its cellular organization.

5. **Choose the Correct Option**: Based on the above points, the correct answer to the question is that the nucleus of Spirogyra lies suspended in the central vacuole.

### Final Answer:
The nucleus of Spirogyra cell lies suspended in the central vacuole.
