Which of these is responsible for grittiness of fruits ?

Options

A. Rod cells
B. Stone cells
C. Vessels
D. Star cells

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which cells are responsible for the grittiness of fruits. This indicates that we need to identify a specific type of cell associated with the texture of certain fruits.

2. **Identifying Key Terms**: The term "grittiness" suggests a texture that is not smooth, which is often associated with certain types of cells in plants.

3. **Researching Fruit Texture**: In plant anatomy, certain cells are known to contribute to the texture of fruits. The cells that are typically associated with a gritty texture are called "stone cells."

4. **Defining Stone Cells**: Stone cells, also known as sclerides, are a type of sclerenchyma cell. These cells have thick, lignified (woody) walls, which contribute to the hardness and grittiness of the fruit.

5. **Function of Stone Cells**: The primary function of stone cells is to provide structural support and strength to the plant tissues. They also help in alleviating stress within the fruit, particularly during over-ripening.

6. **Evaluating the Options**: Given the options provided in the question, we can conclude that the correct answer is the stone cells (sclerides), as they are specifically known for causing the grittiness in fruits.

7. **Final Answer**: Therefore, the cells responsible for the grittiness of fruits are the stone cells (sclerides).
