So you have this little algal forest, and in the size of a laptop you can find more than 100 species of algae, mostly microscopic fit hundreds of species of little animals that then feed the fish, so that the system recovers.

Together with the red algae (Rhodophyta) and green algae plus land plants (Viridiplantae or Chloroplastida), they form the Archaeplastida.

On microscopic inspection, the tumor cells are readily recognized.

Here's some algae in the foreground ...

Algae produce hydrogen under certain conditions.

This is done both on a microscopic and molecular level.

It is similar to linen in absorbency, density and microscopic appearance.

However, the relationships among the red algae, green algae and glaucophytes are unclear, in large part due to limited study of the glaucophytes.

There are about 8,000 species of green algae.

The microscopic test gives false results in nearly half of all cases.

Lichens arose as a co op. Fungi married algae ...

The green algae were similar to today's sea moss.

The green algae and land plants have lost that pigment.

They have no teeth and generally feed on algae and invertebrates.

Though usually microscopic, some species of diatoms can reach up to 2 millimetres in length.

So this is the infamous Caulerpa taxifolia, the so called killer algae.

Well, it's probably microscopic, and it's never easy to study microscopic things, although the amazing tools that we now have to do that allow us to study things in much greater depth, at much smaller scales than ever before.

Synthetic Genomics has a 600 million agreement with ExxonMobil to obtain fuel from algae.

It is an omnivore, feeding on algae and various animals including mussels and limpets.

This algae is then eaten by fish and other organisms higher in the food chain.

It runs down the rivers, and it feeds the plankton, the little microscopic plant cells in the coastal water.

Likewise, if too many herbivorous fish are removed, algae gain a competitive advantage over the corals.

Diatoms are a major group of algae, and are among the most common types of phytoplankton.

History In 1939 a German researcher named Hans Gaffron, while working at the University of Chicago, observed that the algae he was studying, Chlamydomonas reinhardtii (a green algae), would sometimes switch from the production of oxygen to the production of hydrogen.

They are microscopic cylinders of Tamm Horsfall protein that have been precipitated in the kidneys and then released into the urine.

Photolysis of water occurs in the thylakoids of cyanobacteria and the chloroplasts of green algae and plants.

An algal mat is a layer of usually filamentous algae on marine or fresh water soft bottoms.

However, they are absorbed, usually as methyl mercury, by algae at the start of the food chain.

The use of food micro algae to combat acute malnutrition in humanitarian emergencies and for sustainable development

The challenge is to integrate them into the primary health care system, which is also in need of equipment for microscopic diagnosis.

SD2 will drill more than 20 centimetres into the surface, collect samples and deliver them to different ovens or for microscopic inspection.

The color of my teeth now is green because of sea algae, but, they're still prettier than the dictator's teeth.

Many of the coralline algae, which secrete calcium carbonate and play a major role in building coral reefs, belong here.

Histology (compound of the Greek words tissue , and logia science ) is the study of the microscopic anatomy of cells and tissues of plants and animals.

Just an amazing animal, it can change color and texture to match the surroundings. Watch him blend right into this algae.

You have to put in hundreds of microscopic wires to record from little tiny individual neurons ordinary fibers that put out tiny signals that are microvolts.

Steppers are an essential part of the complex process, called photolithography, that creates millions of microscopic circuit elements on the surface of tiny chips of silicon.

The water condition of the rivers has improved since 2001 2007, but there is an increase in population of blue green algae.

So here we are, at a very microscopic scale, swimming around. And I actually realize that cells don't have eyes, but it helps to make it cute.

They start out as small, microscopic nests of cells that can only grow to one half a cubic millimeter in size that's the tip of a ballpoint pen.

Similarly, A. cepistipes and A. gallica are virtually identical in appearance (especially older fruit bodies), and are identified by differences in geographical distribution, host range, and microscopic characteristics.

It accepts algae and detritus in one end, and through this beautiful, glamorous set of stomach organs, out the other end comes cleaner water.

Because on Earth, almost all 99.9 percent of the methane is produced by living systems, not little green men, but microscopic life below the surface or at the surface.

This is my baseline This is the Mediterranean coast with no fish, bare rock and lots of sea urchins that like to eat the algae.

The more nutrients that enter the water (run off from nearby land), the more the algae are favored, until, at some point, they take over.
