why do euglena have chloroplasts
Euglena are small organisms in the Protist Kingdom. Euglena gracilis is just one of many species of Euglena. They do not have common names like birds or trees, so we have to refer to them by their scientific name. Euglena are interesting because they are a sort of combination of plant and animal.. Tsukii. Euglena gracilis and other euglena are green because they eat green algae. They keep the algae inside their bodies and use it to make their own food. These green parts inside the Euglena's body are called chloroplasts.
