Assertion [A]: Euglena can be considered a plant.
Reason [R]: Euglena possesses chloroplast.
Euglenoids are unicellular, aquatic protists that have both plant and animal characteristics. Unlike plant cells, they lack a cell wall made of cellulose. They do have a flexible pellicle made of protein that surrounds the cell membrane. Euglenoids are plant-like in the sense that most of them have chlorophyll and are photosynthesising. However, they are also animal-like because when light is not available, they can ingest food in ways that might remind you of some protozoans. In other words, euglenoids can be facultative heterotrophs. Euglenoids might also resemble protozoans because they have one or more flagella to move.
