A.
Ochrophyta
Ochrophyta is a diverse phylum of mostly photosynthetic, predominantly marine algae that includes brown algae and related groups characterized by chlorophylls a and c and distinctive plastids.
-
B.
Haptophyta
Haptophyta is a diverse group of mostly marine, unicellular algae known for their distinctive flagella and haptonema, many of which play key roles in global carbon cycling and form important components of phytoplankton communities.
-

Chromista
Chromista is a diverse eukaryotic kingdom that includes many algae and protist groups, such as brown algae and diatoms, characterized by complex plastids and often aquatic lifestyles.
-
D.
Phaeophyceae
Phaeophyceae is a class of brown algae, predominantly marine seaweeds, that includes many large, multicellular forms such as kelps and rockweeds.
-
E.
Dinoflagellata
Dinoflagellata is a diverse phylum of mostly marine, often bioluminescent, single-celled protists that play key roles as plankton in aquatic ecosystems and can cause harmful algal blooms.
