Answer:
Archaeplastida
Step-by-step explanation:
Archaeplastida is a supergroup that includes Rhodophyta, Chlorophyta and Viridaeplanta. Rhodophyta includes red algae, Chlorophyta includes green algae while Viridaeplanta includes all the land plants. All of these are the autotrophic organisms and have chlorophyll pigments to perform photosynthesis. Chlorophyll a and b are common to all the members of Archaeplastida which in turn gives green color to the green algae and to the leaves of land plants. Phycoerythrin pigment, in addition to chlorophyll pigments, imparts a red color to red algae.
