What is the number of cells in euglena green and ciliate shoes?

Euglena green and infusoria shoes are unicellular protozoa. They consist of one cell, which has many elements. Moreover, these are not bacteria, but animal organisms. There was a lot of controversy about which kingdom Euglena green belongs to. Some believed that this is a bacterium due to its small size, others that it is a plant, since it has chloroplasts. But still it was possible to determine that this is a single-celled animal. Unicellular organisms can move, feed, and even respond to external stimuli.
