Definition
Phytomastigina is an older taxonomic class of flagellate protozoa that possess chloroplasts, enabling them to perform photosynthesis. They are essentially plant-like protists that can produce their own food using sunlight. Think of them as the tiny, photosynthetic powerhouses of the microbial world. They are found in aquatic environments, contributing to primary production. This group is now largely replaced by more modern classifications. 🌱
