A science teacher asks students to identify an organism under the microscope. The organism is single-celled, has a rigid cell wall, and produces oxygen through photosynthesis. Which organism is most likely being observed?
Cyanobacterium
The organism is single-celled, has a rigid cell wall and makes oxygen by photosynthesis.
Cyanobacteria (blue-green algae) are single-celled prokaryotes with a cell wall and chlorophyll, so they fit all three features.
Paramecium and Amoeba cannot photosynthesise, and Euglena has no rigid cell wall (it has a flexible pellicle).
Hence, the answer is Cyanobacterium.
