Which term denotes the group of green algae?

• A. Cyanobacterium
• B. Dinoflagellate
• C. Foraminifera
• D. Chlorophyta

Answer: (D)

Green algae are categorized by their bright green color from chlorophyll a and b, and they store energy as starch inside chloroplasts. The group that includes these algae is Chlorophyta. This term is used in biology to refer to the diverse range of green photosynthetic organisms found in freshwater and marine environments, from tiny unicellular forms to simple multicellular types like Ulva (sea lettuce) and colonies like Volvox.

Cyanobacteria are photosynthetic bacteria, not algae. Dinoflagellates are a different group of protists, often with distinct plates and typically not green. Foraminifera are calcareous-shelled protists. So Chlorophyta uniquely denotes the green-algae group.
