Chromista include diatoms, ciliates and their relatives. As many of the species in this kingdom can photosynthesise, and have rigid cell walls, they were once thought to be plants. Their members include kelps, the water mould that caused the Irish potato famine and single-celled organisms such as the paramecium.
