A parenchymatous cell that stores ergastic substances is called
(a) Phragmoplast
(b) Idioblast
(c) Leucoplast
(d) Amyloplast

Options

A. Phragmoplast
B. Idioblast
C. Lequoplast
D. Amyloplast

Answer

To solve the question, "A parenchymatous cell that stores ergastic substances is called," we will analyze each option provided and determine which one correctly identifies the type of cell in question.

### Step-by-Step Solution:

1. **Understanding Parenchymatous Cells**:
- Parenchyma is a type of simple tissue found in plants, composed of living cells that are typically involved in storage, photosynthesis, and tissue repair.

2. **Definition of Ergastic Substances**:
- Ergastic substances are non-protoplasmic materials that can be found in plant cells, including storage materials like starch, oils, and other metabolites.

3. **Analyzing the Options**:
- **(a) Phragmoplast**: This is not a type of cell but rather a structure that forms during cell division in plants. Therefore, it is not the correct answer.
- **(b) Idioblast**: This is a specialized parenchymatous cell that can store ergastic substances such as oils, latex, and other excretory materials. This option fits the description given in the question.
- **(c) Leucoplast**: This is a type of plastid involved in the storage of starch, oils, and proteins, but it is not specifically referred to as a cell that stores ergastic substances.
- **(d) Amyloplast**: This is a specific type of leucoplast that primarily stores starch. While it does store a type of ergastic substance, it is not the general term for cells storing various ergastic substances.

4. **Conclusion**:
- Based on the definitions and characteristics of the options, the correct answer is **(b) Idioblast**. This type of parenchymatous cell is specifically known for storing ergastic substances.

### Final Answer:
(b) Idioblast
