Identify the incorrect match.

Options

A. Vesicles - Golgi complex
B. Grana-chloroplast
C. Ribosomes—mitochondria
D. Chromosomes-nucleus

Answer

To identify the incorrect match among the given options, we will analyze each pair one by one:

1. **Vesicles and Golgi Complex**:
- Vesicles are small membrane-bound sacs that transport materials within the cell.
- The Golgi complex is responsible for modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles.
- Vesicles are indeed formed from the Golgi complex and are used to transport substances.
- **Conclusion**: This match is correct.

2. **Grana and Chloroplast**:
- Grana (singular: granum) are stacks of thylakoids found within chloroplasts.
- Chloroplasts are the organelles responsible for photosynthesis, and they contain chlorophyll, which is essential for capturing light energy.
- Grana play a crucial role in the light-dependent reactions of photosynthesis.
- **Conclusion**: This match is correct.

3. **Ribosomes and Mitochondria**:
- Ribosomes are the sites of protein synthesis and can be found free in the cytoplasm or attached to the endoplasmic reticulum (ER).
- Mitochondria are known as the powerhouses of the cell, as they generate ATP through cellular respiration.
- Ribosomes and mitochondria are different organelles with distinct functions and are not directly related.
- **Conclusion**: This match is incorrect.

4. **Chromosomes and Nucleus**:
- Chromosomes are structures that contain genetic material (DNA) and are found within the nucleus of eukaryotic cells.
- The nucleus is often referred to as the brain of the cell because it houses the genetic information.
- **Conclusion**: This match is correct.

Based on the analysis, the incorrect match is **Ribosomes and Mitochondria**.
