Rod shaped elongated sclereids found in the seed coats of pulses are known as

Options

A. Marcrosclereids
B. Brachysclereids
C. Osteoscreids
D. Asterosclereids

Answer

To solve the question regarding the rod-shaped elongated sclereids found in the seed coats of pulses, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the specific type of sclereids that are rod-shaped and elongated, found in the seed coats of pulses.

2. **Define Sclereids**: Sclereids are a type of sclerenchyma cell that provides structural support to plants. They can come in various shapes, including branched, star-shaped, and rod-shaped.

3. **Identify the Types of Sclereids**:
- **Astrosclereids**: These are star-shaped and not rod-shaped, so they do not fit the description.
- **Osteosclereids**: These are bone-like cells found in the hypodermal layer of seeds and fruits, which also do not match the rod-shaped characteristic.
- **Brachysclereids**: These are short and may resemble parenchyma cells, but they are not specifically rod-shaped.
- **Macrosclereids**: These are indeed rod-shaped and elongated, and they are found in the seed coats of pulses.

4. **Conclusion**: Based on the characteristics described, the correct answer to the question is **Macrosclereids**.

### Final Answer:
Rod-shaped elongated sclereids found in the seed coats of pulses are known as **Macrosclereids**.
