Do micro algae do photosynthesis?
1.3. Microalgae are photosynthetic microorganisms found in marine and freshwater environments. Its photosynthetic efficiency is 10 times higher than terrestrial plants, achieving higher growth rates and biomass productivities, with some species doubling their biomass within a few hours.
How efficient is algae biofuel?
The Department of Energy reports that algae have the potential to yield at least 30 times more energy than land-based crops currently used to produce biofuels. Algae also efficiently recycle atmospheric carbon.
How efficient is photosynthesis in algae?
Considering only the incident light on the reactor surface, the typical photosynthetic efficiency registered is around 0.1%–10% and the theoretical maximum value is ∼12% [8]. A factor that can reduce photosynthetic efficiency is photoinhibition, which can occur when microalgae are exposed to too high a flux of photons.
Is Algar photosynthetic?
Algae are a diverse group of predominantly aquatic photosynthetic organisms, including cyanobacteria, green algae and other eukaryotic algae. They account for more than 50% of the photosynthesis that takes place on Earth.
Why are algae not classified as plants if they are photosynthetic?
The main reason is that they contain chloroplasts and produce food through photosynthesis. However, they lack many other structures of true plants. For example, algae do not have roots, stems, or leaves.
Are all photosynthetic organisms plants?
Photosynthetic organisms, also known as photoautotrophs, are organisms that are capable of photosynthesis. Some of these organisms include higher plants, some protists (algae and euglena), and bacteria.

Which of the following is are necessary for biofuel production by photosynthetic algae?
What things to algae need to produce this oil that is high in chemical energy? sunlight, carbon dioxide, water plus a few nutrients.
How do you calculate photosynthetic efficiency?
Therefore, the estimated maximum energy efficiency of photosynthesis is the energy stored per mole of oxygen evolved, 117 kcal, divided by 450—that is, 117/450, or 26 percent.
What are the photosynthetic pigments in algae?
Three major classes of photosynthetic pigments occur among the algae: chlorophylls, carotenoids (carotenes and xanthophylls) and phycobilins. The pigments are characteristic of certain algal groups as indicated below.
What is the adaptive advantage of a photosynthetic organism that is able to move from place to place?
The adaptive advantage that a photosynthetic organism can have in moving from one place to another is to obtain more sunlight.
Is algae a Protista or Plantae?
algae, singular alga, members of a group of predominantly aquatic photosynthetic organisms of the kingdom Protista. Algae have many types of life cycles, and they range in size from microscopic Micromonas species to giant kelps that reach 60 metres (200 feet) in length.
What is the photosynthetic efficiency of microalgae?
Photosynthetic efficiency of microalgae is measured as the ratio between energy supplied to microalgae by light illumination and the energy content of the microalgae biomass produced by photosynthesis.
How feasible is microalgae biofuel production?
According to Gallagher [137], the economic feasibility of microalgae biofuel production seems to be fair and dependent on government subsidies and the future prices of oil. In addition to optimized biomass yields, the requirement of carbon neutral renewable alternatives makes microalgae one of the best future sources of biofuels [16].
Are oil rich microalgae a realistic feedstock for large-scale biofuels?
Oil rich microalgae have emerged as the most realistic feedstock for the large-scale production of biofuels as they do not require fresh water ( Stephenson et al., 2011 ).
Can algae help improve biofuel combustion?
These successful experiments suggest that improving lipid production in algae is a tenable option to improve biofuel charactieristics. Improving fuel molecules Algae can be harnessed to produce a number of molecules that can be used for fuels.
