Algae are aquatic, plant-like organisms. They encompass a variety of simple structures, from single-celled phytoplankton floating in the water, to large seaweeds macroalgae attached to the ocean floor 2.
However, all phytoplankton are algae. In addition, not all phytoplankton are marine algae. Marine phytoplankton, also known as marine microalgae, comprise thousands of species of photosynthetic, unicellular organisms belonging to the Kingdom Protista.
Temperate coastal waters, such as those along British Columbia BCexperience high levels of productivity and support a diverse array of microalgal species from numerous groups called classes. Technically, algae are not plants because they lack a vascular system.
Simply put, all phytoplankton are microalgae, but not all microalgae occur in the plankton. Although these terms have helped, much confusion still exists.
Among the various classes of phytoplankton you find marine, freshwater and terrestrial based species. So, just because someone labels a product microalgae or phytoplankton the reality of what they are using is usually different.
These organisms generally require extreme conditions to grow, conditions which facilitate easy cultivation due to low risk of contamination by fungus and bacteria, or by other microalgae. For instance, Dunaliella salina requires very high salanites while cyanobacteria like Spirulina platensis need highly alkaline conditions.
Most microalgae species, however, grow best in conditions that are optimal for hundreds of other species. This is primarily why so much research is directed to scaling up photobioreactors — enclosed growth chambers where all aspects of the environment are controlled and contamination is minimized.
The most important thing to remember when dealing with algae is that not all algae are phytoplankton.This study was undertaken to determine if there were differences in net primary productivity, gross primary productivity, and respiration for the lake and pond found in Fullerton Arboretum Pond System.
Main Difference – Algae vs Microalgae. Algae and microalgae are photosynthetic organisms that serve as an excellent food source in aquatic grupobittia.com can be categorized into microalgae and macroalgae. Microalgae are called phytoplankton and macroalgae are called seaweeds. UNESCO – EOLSS SAMPLE CHAPTERS MARINE ECOLOGY – Productivity of the Oceans - grupobittia.comrst ©Encyclopedia of Life Support Systems (EOLSS) though the principles will be similar.
In the ocean, it is evident that regional oceanographic processes shall exert important control on the ecology of phytoplankton.
