Which one is non-living cell inclusion ?

Options

A. Golgi complex
B. Centrosome
C. Vacuole
D. Ribosomes

Answer

To determine which option is a non-living cell inclusion, let's analyze each option provided in the question:

1. **Colgi complex**: The Golgi complex (or Golgi apparatus) is an organelle involved in modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles. It is a living structure, as it plays an active role in cellular processes.

2. **Centrosome**: The centrosome is an organelle that serves as the main microtubule organizing center of the cell and is crucial for cell division. It is also a living structure, as it participates in the organization of the cell's cytoskeleton and the process of mitosis.

3. **Ribosome**: Ribosomes are molecular machines that synthesize proteins by translating messenger RNA (mRNA). They can be found free in the cytoplasm or attached to the endoplasmic reticulum. Ribosomes are essential for protein synthesis and are considered living structures because they are involved in vital cellular functions.

4. **Vacuole**: Vacuoles are membrane-bound compartments within cells that can store various substances, including waste products, nutrients, and other materials. In plant cells, vacuoles are typically larger and can serve as storage or even help maintain turgor pressure. The vacuole can be considered a non-living cell inclusion because it primarily serves as a storage space and does not actively participate in metabolic processes.

Based on this analysis, the non-living cell inclusion among the options is the **vacuole**.

### Step-by-Step Solution:
1. **Identify the options**: The options given are Golgi complex, centrosome, vacuole, and ribosome.
2. **Analyze the Golgi complex**: Determine its function and conclude it is a living structure.
3. **Analyze the centrosome**: Determine its role in cell division and conclude it is a living structure.
4. **Analyze the ribosome**: Understand its role in protein synthesis and conclude it is a living structure.
5. **Analyze the vacuole**: Recognize its function as a storage compartment and conclude it is a non-living cell inclusion.
6. **Conclude**: Identify the vacuole as the non-living cell inclusion.
