Most algae are open to water flows, immediately and directly accessing water-borne gasses and nutrients, with no vascular systems to delay the process. This and other factors result in algae metabolizing at 10X to 50X the rate of terrestrial plants. Plants have a vascular system, a pseudo-circulatory system that requires time to bring gas and nutrients into the plant and distribute them. So, although it may appear stagnant, algae grow and perform nearly all metabolic activity much faster than plants.
