What is the difference between brown and green algae?

What are the characteristics of brown algae?
Brown Algae. Phaeophyceae or brown algae are distinguished by chloroplasts that have four surrounding membranes, thylakoids in stacks of three, fucoxanthin that masks chlorophyll-a and -c, laminarin as the photosynthetic reserve, and alginates commonly as the wall matrix component.
What color light does brown algae absorb?
Brown pigments can absorb the
blue-green
light energy and pass it to the green chlorophyll for photosynthesis (a process whereby algae manufacture food from carbon dioxide and water using light energy).
What is brown algae called?
brown algae, (
class Phaeophyceae
), class of about 1,500 species of algae in the division Chromophyta, common in cold waters along continental coasts. Species colour varies from dark brown to olive green, depending upon the proportion of brown pigment (fucoxanthin) to green pigment (chlorophyll).
