Which originated first:

Options

A. Prokaryotic cell
B. Eukaryotic cell
C. Green algae
D. None of these

Explanation

**Step-by-Step Solution:**

1. **Identify the Options**: The question asks which of the given options originated first. The options are:
- Prokaryotic cell
- Eukaryotic cell
- Green algae
- None of these

2. **Analyze Prokaryotic Cells**: Prokaryotic cells are single-celled organisms that are known to be the earliest forms of life on Earth. They include bacteria and archaea. This indicates that prokaryotic cells were among the first life forms to appear.

3. **Analyze Eukaryotic Cells**: Eukaryotic cells are more complex than prokaryotic cells and include organisms such as plants, animals, fungi, and protists. Eukaryotic cells evolved from prokaryotic cells, meaning that they originated after prokaryotes.

4. **Analyze Green Algae**: Green algae are a type of photosynthetic eukaryote. Since they are classified as eukaryotes, they also originated after prokaryotic cells.

5. **Analyze the Option "None of These"**: This option suggests that none of the previous options are correct. However, since we have established that prokaryotic cells are the earliest life forms, this option is incorrect.

6. **Conclusion**: Based on the analysis, the first to originate among the given options is the prokaryotic cell.

**Final Answer**: Prokaryotic cell originated first.
