Which cell organelle store food and water in a plant ?

Options

A. Mitochondria
B. Ribosomes
C. Vacuole
D. Endoplasmic reticulum

Answer

**Step-by-Step Solution:**

1. **Identify the Organelles**: The question asks which cell organelle is responsible for storing food and water in plants. The options provided are mitochondria, ribosomes, vacuole, and endoplasmic reticulum.

2. **Analyze Each Option**:
- **Mitochondria**: Known as the powerhouse of the cell, mitochondria are primarily responsible for producing energy (ATP) through cellular respiration. They do not store food or water.
- **Ribosomes**: Ribosomes are known as the protein factories of the cell. They are involved in protein synthesis and do not store food or water.
- **Vacuole**: Vacuoles are large organelles in plant cells that can occupy up to 90% of the cell's volume. They are responsible for storing water, nutrients, and waste products. The membrane surrounding the vacuole is called the tonoplast.
- **Endoplasmic Reticulum (ER)**: The ER is involved in the synthesis of proteins (rough ER) and lipids (smooth ER). It does not store food or water.

3. **Conclusion**: Based on the analysis, the organelle that stores food and water in plant cells is the **vacuole**.

**Final Answer**: The cell organelle that stores food and water in a plant is the **vacuole**.
