Golgi apparatus is absent in

Options

A. higher plants
B. yeast
C. bacteria and blue-green algae
D. None of the above

Explanation

### Step-by-Step Solution:

1. **Understanding the Golgi Apparatus**: The Golgi apparatus is a cell organelle involved in the synthesis, modification, sorting, and packaging of proteins and lipids. It is characterized by its well-defined structure and double membrane.

2. **Classification of Organisms**: Organisms can be classified into two main categories: eukaryotes and prokaryotes.
- **Eukaryotes**: These organisms have a well-defined nucleus and membrane-bound organelles, including the Golgi apparatus. Examples include higher plants and yeast.
- **Prokaryotes**: These organisms do not have a well-defined nucleus or membrane-bound organelles. Instead, they have a nucleoid region where their genetic material is located. Examples include bacteria and blue-green algae.

3. **Analyzing the Options**:
- **Option 1: Higher Plants**: Higher plants are eukaryotic organisms and possess a Golgi apparatus. Therefore, this option is not correct.
- **Option 2: Yeast**: Yeast is a unicellular eukaryote and also contains a Golgi apparatus. Thus, this option is not correct either.
- **Option 3: Bacteria and Blue-Green Algae**: Both bacteria and blue-green algae are prokaryotic organisms. They lack a well-defined nucleus and membrane-bound organelles, including the Golgi apparatus. Therefore, this option is correct.

4. **Conclusion**: Based on the analysis, the Golgi apparatus is absent in bacteria and blue-green algae, which are examples of prokaryotic organisms.

### Final Answer:
The Golgi apparatus is absent in **bacteria and blue-green algae** (Option 3).
