Morphology
The meaning 'a type of algae that is red or purplish' is directly and transparently derived from combining 'red' (the color) with 'algae' (plant-like organisms). This is a straightforward adjective + noun composition common across languages, so a B1 learner who knows both words would readily infer the MWE's basic meaning (even if technical uses like agar are unfamiliar).
Etymology
Red algae gets its name from the sea plants' colour: red or purple colours cover their green so the plants look red and are called algae. That's why red algae now means these sea plants often used to make agar and nori.
