Short answer

The correct answer is (d) All of these

Step-by-step solution

Understanding Plastids

Plastids are a group of organelles commonly found within the cells of plants and algae. They are also observed in plant-like protists such as Euglena. These include chloroplasts, chromoplasts, and leucoplasts each serving a unique function in the cell.

Recognizing Different Types of Plastids

Chloroplasts are a type of plastid that are green in color and where photosynthesis takes place. Chromoplasts are plastids that contain colorful pigments and may or may not take part in photosynthesis. Leucoplasts are colorless plastids that store important materials like starch, lipids, or proteins.

Answering the Question

Based on the information above, it is clear that chloroplasts, chromoplasts, and leucoplasts are all types of plastids. Therefore, the correct answer is (d) All of these
