What is Cyanophyta in biology?

cyanobacteria: Cyanobacteria, also known as blue-green bacteria, blue-green algae, and Cyanophyta, is a phylum of bacteria that obtain their energy through photosynthesis.

Where is Merismopedia found?

Merismopedia (from the Greek merismos and the Greek pedion ) is a genus of cyanobacteria found in fresh and salt water. It is ovoid or spherical in shape and arranged in rows and flats, forming rectangular colonies held together by a mucilaginous matrix.

What is Synechococcus Lividus?

Synechococcus lividus is a species of Bacteria in the family Synechococcaceae.

What is the order of Merismopedia?

Integrated Taxonomic Information System – Report

Why Cyanophyceae is called cyanobacteria?

What are Cyanobacteria? Cyanobacteria, formerly known as blue-green algae, are photosynthetic microscopic organisms that are technically bacteria. They were originally called blue-green algae because dense growths often turn the water green, blue-green or brownish-green.

What type of bacteria is oscillatoria and what is its purpose?

Oscillatoria uses photosynthesis to survive and reproduce. Each filament of oscillatoria consists of trichome which is made up of rows of cells. The tip of the trichome oscillates like a pendulum….

Is Merismopedia a colonial?

Merismopedia comprises flattened, free-living, platelike (rectangular), more or less rectangular colonies that have one layer of cells, arranged loosely or densely in perpendicular rows and enveloped by fine, colorless, usually indistinct, and marginally diffuse mucilage. Reproduction is by fragmentation of colonies.

Does Merismopedia have chlorophyll?

Like a microscopic (and monochromatic) version of Tetris, Merismopedia cells form square-packed colonies. These cyanobacteria, plucked from a New England salt marsh, were flooded with ultraviolet light that was later filtered out of the image to reveal a red hue produced by chlorophyll molecules inside the cells.

Why did cyanobacteria survive?

When cyanobacteria live in low-light conditions, some can switch to using far-red sunlight. Scientists have determined the structure of the protein complex that gives cyanobacteria their unique ability to convert weak, filtered sunlight into useable energy.

When did cyanobacteria appear on Earth?

The cyanobacteria fossil record starts around 1.9 billion years ago with the most emblematic Proterozoic microfossil identified so far with certainty as a cyanobacterium, Eoentophysalis belcherensis (Fig. 1A).

How do Merismopedia reproduce?

Merismopedia cells are gram-negative, blue-green in color. They grows as unicellular organisms in colonial form, reproducing in two fission planes to form plate-like colonies consisting of up to 4000 cells (Komárek). Reproducing specifically by fission, cell division occurs in two directions only (Manhattan).

Does Merismopedia move?

Merismopedia can move using filaments called hormogonia.
