Do protozoa have plastids

Protozoa generally do not have plastids, as these organelles are primarily found in plants and some algae, where they are involved in photosynthesis. However, certain protozoan groups, such as euglenoids, contain plastid-like structures called chloroplasts that allow them to perform photosynthesis. These chloroplasts are derived from endosymbiotic algae. Overall, while most protozoa lack plastids, some specialized forms do possess them.
