Answer

To answer the question about colorless (non-pigmented) plastids, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Plastids**: Plastids are organelles found in plant cells that are involved in the synthesis and storage of food. They can be classified based on their color and function.

2. **Identifying Types of Plastids**:
- **Leucoplasts**: These are colorless plastids that do not contain pigments. Their primary function is to store food substances such as starch, oils, and proteins.
- **Chloroplasts**: These plastids contain green pigments (chlorophyll) and are involved in photosynthesis, giving plants their green color.
- **Chromoplasts**: These are colored plastids that contain pigments other than chlorophyll, contributing to the color of fruits and flowers.

3. **Analyzing the Options**:
- The question specifically asks for colorless (non-pigmented) plastids.
- Among the options, **leucoplasts** are identified as the only type that is colorless and non-pigmented.

4. **Conclusion**: Based on the analysis, the correct answer to the question is **leucoplast**.

### Final Answer:
The colorless (non-pigmented) plastids are **leucoplasts**.
