Leucoplasts are plastids that

Options

A. carry photosynthesis
B. give colour to fruits
C. are colourless
D. contain carotenoid pigments

Answer

**Step-by-Step Text Solution:**

1. **Understanding Leucoplasts**: Leucoplasts are a type of plastid found in plant cells. They are known for being colorless, which differentiates them from other types of plastids like chloroplasts (which are green due to chlorophyll) and chromoplasts (which contain pigments that give color to fruits and flowers).

2. **Function of Leucoplasts**: The primary function of leucoplasts is to store food. They are involved in the synthesis and storage of various organic compounds, including starch, proteins, and fats. This storage function is crucial for the plant, especially in non-photosynthetic parts like roots and tubers.

3. **Location in Plants**: Leucoplasts are typically found in parts of the plant that do not engage in photosynthesis, such as underground roots and stems. This is because they do not require light and are adapted for storage rather than photosynthesis.

4. **Comparison with Other Plastids**: Unlike chloroplasts, which contain chlorophyll and are involved in photosynthesis, and chromoplasts, which contain carotenoid pigments that provide color, leucoplasts lack these pigments and are therefore colorless.

5. **Conclusion**: Given the characteristics and functions of leucoplasts, the correct statement is that "leucoplasts are plastids that are colorless."

**Final Answer**: Leucoplasts are plastids that are colorless.
