Answer 1

The correct answer is Rhodophyceae.

Key Points

Rhodophyceae is commonly known as red algae.
Red algae are primarily found in marine environments, although some species can also be found in freshwater.
The red color in these algae is due to the presence of phycoerythrin, a pigment that absorbs blue light and reflects red light.
They are an important source of agar and carrageenan, which are used in food and pharmaceutical industries.
Red algae play a crucial role in marine ecosystems by providing habitat and food for various marine organisms.
They are also involved in the formation of coral reefs by contributing to the calcium carbonate structure.
