Idioblast is

Options

A. A dissimilar cell with inclusions
B. A cell without inclusions
C. Cell inclusion
D. Cell organelle.

Answer

To answer the question "Idioblast is," we need to analyze the options provided and understand what an idioblast is in the context of plant biology.

### Step-by-Step Solution:

1. **Definition of Idioblast**: An idioblast is a specialized plant cell that differs from the surrounding cells in structure and function.

2. **Characteristics of Idioblasts**: These cells are often characterized by the presence of inclusions, which are specialized structures or materials stored within the cell.

3. **Functions of Idioblasts**: The main functions of idioblasts include:
- Storage of reserves (like oils, starch, etc.)
- Storage of excretory materials (substances that need to be expelled from the plant)
- Storage of pigments (which can be involved in photosynthesis or provide color)
- Storage of minerals (which are essential for various plant functions)

4. **Examples of Stored Materials**: Common inclusions found in idioblasts include:
- Oils
- Latex
- Gum
- Resin
- Tannins
- Pigments

5. **Conclusion**: Based on the definition and characteristics of idioblasts, the correct answer to the question is that an idioblast is a "dissimilar cell with inclusions." This is because idioblasts are distinct from neighboring cells and contain various cytoplasmic inclusions.

### Final Answer:
**Idioblast is a dissimilar cell with inclusions.**
