MICROANATOMY

Detailed explanation-1: -All algae use chlorophyll a to collect photosynthetically active light.

Detailed explanation-2: -Photosynthesis is the biochemical process by which plants, algae and certain bacteria can convert the sun’s energy into chemical energy in the form of carbohydrates.

Detailed explanation-3: -Red pigment allows the red algae to photosynthesize at deeper depths than the green or brown algae, harnessing more of the blue light waves that penetrate deeper into the water column. Unlike green algae and plants, red algae store carbohydrates as Floridean starch in the cytosol.
