Grittiness of fruit in pears is due to -

Options

A. Presence of Silica
B. Presence of stone cells / sclereids
C. Presence of raphids
D. Formation of cystolith

Answer

**Step-by-Step Solution:**

1. **Understanding the Grittiness of Pears:**
- The grittiness of fruit, specifically in pears, is a characteristic feature that can be attributed to certain types of cells present in the fruit's structure.

2. **Identifying the Relevant Cell Types:**
- In pears, the grittiness is primarily due to the presence of specialized cells known as sclerids. These cells contribute to the texture and hardness of the fruit.

3. **Focusing on Breaky Sclerids:**
- Among the various types of sclerids, the specific type responsible for the grittiness in pears is called "brachysclereids." These are short, thick-walled cells that provide a gritty texture.

4. **Excluding Other Options:**
- The other options provided (presence of silica, presence of refits, and formation of systolic) do not contribute to the grittiness of pears. Silica is not present, and refits (which are not relevant in this context) do not play a role in the texture.

5. **Conclusion:**
- Therefore, the grittiness of fruit in pears is due to the presence of brachysclereids, which are a type of sclerid.

**Final Answer:**
The grittiness of fruit in pears is due to the presence of brachysclereids (sclerids).
