Cell organelle that mediates the biosynthesis of cutin and wax is

Options

A. Ribosome
B. Flagella
C. Sphaerosome
D. centrosome

Answer

To answer the question regarding which cell organelle mediates the biosynthesis of cutin and wax, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the specific organelle involved in the biosynthesis of cutin and wax. Cutin is a waxy substance that forms a protective layer on plant surfaces.

2. **Evaluate the Options**: The options provided are:
- Ribosomes
- Flagella
- Spherosomes
- Centrosome

3. **Analyze Each Option**:
- **Ribosomes**: These organelles are primarily involved in protein synthesis, not in the synthesis of lipids or waxes. Therefore, this option is incorrect.
- **Flagella**: Flagella are structures that aid in cell movement. They do not play a role in the biosynthesis of cutin or wax, making this option incorrect as well.
- **Spherosomes**: These are small organelles involved in the storage and synthesis of lipids. They are known to mediate the biosynthesis of cutin and wax, making this option likely correct.
- **Centrosome**: This organelle is involved in cell division and does not participate in the synthesis of cutin or wax. Hence, this option is incorrect.

4. **Identify the Correct Answer**: Based on the analysis, the correct answer is **Spherosomes** since they are responsible for the biosynthesis of cutin and wax.

### Final Answer:
The cell organelle that mediates the biosynthesis of cutin and wax is **Spherosomes**.
