Golgi apparatus does not occur in

Options

A. Yeast
B. Liver cells
C. Higher plants
D. Bacteria and blue green algae.

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks in which organism the Golgi apparatus does not occur.

2. **Identifying Organism Groups**: Organisms can be broadly categorized into two groups: prokaryotes and eukaryotes. Prokaryotes include all members of the kingdom Monera, which are primarily bacteria. Eukaryotes include organisms such as fungi, plants, and animals.

3. **Characteristics of Prokaryotes**: Prokaryotic cells lack membrane-bound organelles. This means they do not have structures like the Golgi apparatus, endoplasmic reticulum, or mitochondria. Instead, their genetic material is found in a region called the nucleoid, and they have simpler cellular structures.

4. **Characteristics of Eukaryotes**: Eukaryotic cells, on the other hand, possess membrane-bound organelles, including the Golgi apparatus, endoplasmic reticulum, mitochondria, and others. This includes organisms such as yeast (a fungus), liver cells (animal cells), and higher plants.

5. **Identifying the Correct Answer**: Since the Golgi apparatus is a membrane-bound organelle, it will be absent in prokaryotic organisms. Therefore, the correct answer to the question is that the Golgi apparatus does not occur in prokaryotes, specifically in bacteria and cyanobacteria (blue-green algae).

6. **Conclusion**: The correct option is the one that refers to prokaryotic organisms, which is option number 4.

### Final Answer:
The Golgi apparatus does not occur in prokaryotes, specifically in bacteria and cyanobacteria.
