Algae in a sentence

Algae In some multicellular green algae ( Ulva lactuca is one example), red algae and brown algae sporophytes and gametophytes may be externally indistinguishable (isomorphic).

Harvey's four divisions are: red algae (Rhodospermae), brown algae (Melanospermae), green algae (Chlorospermae) and Diatomaceae. citation Harvey, D. (1836).

However, complex multicellular organisms evolved only in six eukaryotic groups: animals, fungi, brown algae, red algae, green algae, and plants.

The most recent sampling by the Lee County Environmental Lab found elements related to blue-green algae at the Alva Boat Ramp as visible specks on the surface and in the water column, but no surface patches of algae.

The scientists found that certain combinations of volatile organic compounds (VOCs) released by algae can serve as indicator for microcystin, a produced at varying levels during blooms of cyanobacteria, commonly known as blue-green algae.

They are also found in the microscopic algae that brine shrimp eat (which is why shrimp turn pink when you cook them) and as flamingos eat the algae and brine shrimp, they also turn flamingos’ feathers pink!

Eutrophication causes an outbreak of algae in rivers and streams; the algae deplete the oxygen that can cause marine plants and animals to die.

Avoid areas of algae accumulation and do not let people/pets eat dried algae or drink contaminated water.

The difficult one to find is the Silver Algae, mostly because of the Great Shark; just throw in a bait and the algae will be salvageable.

Decreased peak flow is not as effective at scouring algae off the stream bed, so algae remains on the substrate from one year to the next.

Algae At least 100 species of terrestrial algae are known from Heard Island, commonly in permanently moist and ephemeral habitats.

A phytoplankton community dominated by green algae or cyanobacteria (blue-green algae) tint the water south of the causeway a greenish color.

A reduction in the number of tadpoles may lead to an overgrowth of algae, resulting in depletion of oxygen in the water when the algae later die and decompose.

Due to the strain the algae can put on the polyp, stress on the coral often drives them to eject the algae.

Green algae and plants keep their starch inside their chloroplasts, and in plants and some algae, the chloroplast thylakoids are arranged in grana stacks.

However, not all bodies of water can carry all species of algae, as the chemical composition of certain water bodies will limit the algae that can survive within it.

In red algae, the action spectrum is blue-green light, which allows these algae to use the blue end of the spectrum to grow in the deeper waters that filter out the longer wavelengths (red light) used by above ground green plants.

Only salt-tolerant micro-algae survive in the high salinity ponds, and impart a deep red color to these ponds from the pigment within the algae protoplasm.

Plants and algae Microscopic algae and plants provide important habitats for life, sometimes acting as hiding places for larval forms of larger fish and foraging places for invertebrates.

Ruppert, Fox & Barnes (2004) p. 893 Many sea urchins feed on algae, often scraping off the thin layer of algae covering the surfaces of rocks with their specialised mouthparts known as Aristotle's lantern.
