Sentences with phrase «photosynthetic cells»

Golden speculates that this timepiece «tells photosynthetic cells when to get their biochemistry geared up for dawn, whether they're of generation one or generation four.»

The best explanation, says Hayes, is that these hydrocarbons were formed by «heterotrophic» bacteria, which fed by rotting down the organic material from dead photosynthetic cells.

His reengineered photosynthetic cells would take in carbon dioxide and sunlight and spew out hydrocarbons ready for the ExxonMobil refinery (the oil giant that has provided Venter's company Synthetic Genomics with $ 300 million in funding to date).

Not exact matches

«This is probably because cyanobacteria are naturally photosynthetic — they're actually responsible for a large fraction of the photosynthesis in the ocean — and so whether the cell is energized or not is a good indication of whether it's day or night,» he says.

The corals eat but don't digest these single - celled photosynthetic algae, which then reside inside the corals and feed them the carbon sugars created during photosynthesis.

He and colleagues have determined what gives cholera bacteria their curved shape and whether it matters (a polymer protein, and it does matter; the curve makes it easier for cholera to cause disease), how different wavelengths of light affect movement of photosynthetic bacteria (red and green wavelengths encourage movement; blue light stops the microbes in their tracks), how bacteria coordinate cell division machinery and how photosynthetic bacteria's growth changes in light and dark.

So just as different cells in a leaf contain different amounts of chlorophyll, coral cells seem to house different amounts of the photosynthetic algae that makes their food, Symbiodinium.

Huang teamed up with other researchers to do microfluidics experiments, growing bacteria in tiny chambers and tracking individual cells to learn how photosynthetic bacteria grow in light and dark.

To remedy that absence, Golden's lab, along with plant physiologist Takao Kondo and colleagues at Nagoya University in Japan, developed an easy - to - read gauge of changing photosynthetic activity in colonies of the cyanobacterium Synechococcus, a blue - green alga whose one - celled organisms divide as often as once every 5 to 6 hours.

Because mitochondria and the photosynthetic chloroplasts are derived from joint bacterial ancestors, the study not only contributes to a better understanding of the formation and function of the cells» powerhouses, but also provides new insights into the formation of chloroplasts and bacteria.

For one of them, you can thank plankton, in particular the single - celled photosynthetic drifters that comprise the phytoplankton of the world's oceans.

The work is part of a growing field called optogenetics, and used light - activated proteins from photosynthetic algae to switch nerve cells on and off.

Using high - performance computing and genetic engineering to boost the photosynthetic efficiency of plants offers the best hope of increasing crop yields enough to feed a planet expected to have 9.5 billion people on it by 2050, researchers report in the journal Cell.

However, much of this work is still in its nascent stages,» said Binghamton University Electrical and Computer Science Assistant Professor Seokheun Choi, who is one of the co-authors of «Self - sustaining, solar - driven bioelectricity generation in micro-sized microbial fuel cell using co-culture of heterotrophic and photosynthetic bacteria,» along with PhD candidate Lin Liu.

The team from Bochum is already looking for ways to optimise the «cell factories»; more specifically: the researchers are striving to improve photosynthetic electron transport.

«We need liquid cells for CLAIRE to study the dynamic organization of light - harvesting proteins in photosynthetic membranes,» Ginsberg says.

Subsequently, some aerobic (or oxygen - breathing) protists merged with photosynthetic bacteria, which became chloroplasts and other plastids, to create free - swimming green algae and the precursors of today's plant cells.

Endosymbiotic theory posits a later parallel origin of the chloroplasts; a cell ate a photosynthetic cyanobacterium and failed to digest it.

We found that Phytophthora palmivora can colonise the photosynthetic tissues of the liverwort Marchantia polymorpha by invading living cells.

Plastids, including chloroplasts, are the corresponding photosynthetic organelles of plant and algae cells.

In an algae - eat - algae world, it's the single - celled photosynthetic organisms at the top (layer of the ocean) that absorb the most sunlight.

These solar cells utilise the photosynthetic properties of microorganisms such as algae to convert light into electric current that can be used to provide electricity.

Structurally, chlorella is a higher life form than spirulina, Spirulina is classified as a photosynthetic bacterium, while chlorella is a plant with a cell nucleus, making it exactly like the advanced fruits and vegetables we eat everyday.

Chlorella, belonging to the division Chlorophyta, is a single - cell green algae containing the green photosynthetic pigments chlorophyll - a and - b in its chloroplast.

These single - celled organisms are the principal agents of photosynthetic carbon fixation in the ocean.

Under these conditions the rate may only slightly exceede the respiration rate, so the net photosynthetic production by the cells is actually very poor.

«The operating principles of artificial photosynthetic systems are similar to redox flow batteries and fuel cells in that charge - carriers need to be transported to electrodes, reactants need to be fed to catalytic centers, products need to be extracted, and ionic transport both from the electrolyte to catalytic centers and across channels needs to occur,» Ager says.
