Final answer:
Chrysophyta, or golden algae, have gold-brown colored chloroplasts due to chlorophyll a, chlorophyll c1/c2, and fucoxanthin pigments.
Step-by-step explanation:
Chrysophyta, also known as golden algae, are part of the stramenopile group and have chloroplasts containing chlorophyll a, chlorophyll c1/c2, and fucoxanthin as photosynthetic pigments. This unique combination of pigments gives Chrysophyta their characteristic gold-brown color. Therefore, Chrysophyta have gold-brown colored chloroplasts.
