Yellow-green algae are the Xanthophyceae (xanthophytes).

They are a group of heterokont algae. Most live in fresh water, but some live in marine and soil habitats. They vary from single-celled flagellates to simple colonial and filamentous forms.

Xanthophyte chloroplasts contain the photosynthetic pigments chlorophyll a, chlorophyll c, β-carotene, and the carotenoid diadinoxanthin.^[7]

Unlike other heterokonts, their chloroplasts do not have fucoxanthin, which accounts for their lighter colour. Xanthophyte cell walls are made of cellulose and hemicellulose.^[7] They may be the closest relatives of the brown algae.
