Like land plants, phytoplankton use sunlight to convert carbon dioxide (CO2) and water into organic carbon and oxygen. CO2 is therefore an essential nutrient for phytoplankton and higher concentrations of CO2 in the surface ocean have the potential to support higher rates of phytoplankton photosynthesis and growth.

Phytoplankton photosynthesis

Aquaculturists are well aware that phytoplankton photosynthesis is a major source of dissolved oxygen in ponds. The rate of photosynthesis depends upon the amount of light. Photosynthesis begins at dawn, and on a typical day, photosynthesis rate and dissolved oxygen concentration in the water increase from morning until mid-day or early afternoon. What is photosynthesis and what does it have to do with plankton?

On geological time scales there is profound evidence of the importance of phytoplankton photosynthesis in biogeochemical cycles.

Phytoplankton photosynthesis

Phytoplankton is an important source of dissolved oxygen. In the daytime, these plants produce oxygen by photosynthesis at a much faster rate than oxygen can diffuse from the atmosphere into the pond water. Phytoplankton rapidly removes ammonia nitrogen from the water lessening the concentration of this potentially toxic substance.

Line identi- Phytoplankton Cell Size and Photosynthesis All aspects of the life of phytoplankton are influenced by its size (Chisholm, 1992), which affects it's growth, metabolism and access to resources, and in turn shapes it's ecological niche (Lichtman and Klausmeier, 2008). Total Chl a tends to increase with increasing cell size (Chisholm, 1992). The PI (or photosynthesis-irradiance) curve is a graphical representation of the empirical relationship between solar irradiance and photosynthesis.A derivation of the Michaelis–Menten curve, it shows the generally positive correlation between light intensity and photosynthetic rate. Phytoplankton species deviates from norm: No CO2 absorbed in photosynthesis Findings could affect scientists’ understanding of amount of carbon dioxide phytoplankton pull from atmosphere NASA Background Clarifying the relationship between photosynthesis and irradiance and accurately quantifying photosynthetic performance are of importance to calculate the productivity of phytoplankton Largely using recent data from Tara Oceans, here we review the geographic distributions of phytoplankton in the global ocean and their diversity, abundance, and standing stock biomass. We also discuss how omics-based information can be incorporated into studies of photosynthesis in the ocean and show the likely importance of mixotrophs and photosymbionts. Phytoplankton are all beings of plant origin that are found floating on the oceans' surface, they are autotrophic beings that have the capacity to perform photosynthesis and that serve as primary producers in the ocean's food chain. Phytoplankton is an important source of dissolved oxygen.

In the second part they repeated the iron infusions and it boosted the phytoplankton photosynthesis. The algae grew in number and used more carbon dioxide. Phytoplankton in the sea probably account for more than 50% of global photosynthesis, although there is considerable uncertainty about this estimate.
