Bacillariophytas (Diatoms)
Diatoms are unicellular. Diatoms have regular organelles including a nucleus and mitochondria.
In addition, they have chromatophores, which contain chlorophyll and other pigments. These diatoms have a wall (frustule) around them made out of silica. This makes it look like a glass wall that reflects the environment around it. This is why diatoms look so different.
