During photosynthesis phytoplankton capture and store solar energy through photosynthesis where they remove carbon dioxide from seawater, and release oxygen as a by-product. Through photosynthesis, phytoplankton consume carbon dioxide on a scale equivalent to forests and other land plants.

Thank you to the Monterey Bay Aquarium for partnering with us on this episode of SciShow.

Photo-inhibition is represented as an impediment to this electron flow. Examples are shown of fits to various typical light saturation curves for natural Eight different mathematical formulations of the photosynthesis—light curve for phytoplankton (up to and including light saturation) were recast in terms of the same two parameters: the initial slope α, and the assimilation number PmB. Each equation was tested for its ability to describe empirical data from natural populations of marine phytoplankton: the results of 188 light-saturation Photosynthesis in Phytoplankton: Insights from theNewlyDiscoveredBiologicalInorganicCarbon Pumps Aquatic CO 2 assimilation results in storage in the oceans of 24% of Phytoplankton photosynthesis is an important cycle to understand in order to estimate ocean primary productivity. The most common or standard method used to calculate primary productivity is 14C analysis.

Phytoplankton account for about half of all photosynthetic activity on Earth. Phytoplankton are responsible for most of the transfer of carbon dioxide from the atmosphere to the ocean. Carbon dioxide is consumed during photosynthesis, and the carbon is incorporated in the phytoplankton, just as carbon is stored in the wood and leaves of a tree.

On the most basic level, phytoplankton photosynthesis can be categorized as either light-limited photosynthesis or light-saturated photosynthesis . At low irradiances, the rate of phytoplankton photosynthesis is light limited and proportional to the supply of irradiance.
