Is Merismopedia unicellular?
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).
How is the colony of Merismopedia arranged?
Merismopedia has cells arranged in perpendicular rows one cell thick to form rectangular colonies. The colonies may be flat or slightly wavy and are held together by colorless, indistinct mucilage. Except for a few species, the colonies are usually microcopic, and may have subcolonies.
Is Merismopedia prokaryotic or eukaryotic?
Does Merismopedia have mucilage?
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.
How is the shape of Merismopedia different from other cyanobacteria?
How is the shape of Merismopedia different from other cyanobacteria? It is a flat, square colony, one cell layer thick.
Does Merismopedia have Heterocysts?
Colonial structure: Cells align their long axis to the colony long axis. 1.2–6.5μm in diameter. Thylakoids are arranged parietally. Heterocysts: Absent.
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.
Is Gloeocapsa multicellular Why or why not?
Do clusters of Gloeocapsa represent multicellular organisms? Why or why not? No, they aren’t dependent on each other; the aggregation of cells can be broken into individual cells without killing the cells.
What are trichomes cyanobacteria?
1. An outgrowth from an epidermal cell (e.g. a root hair). 2. In certain bacteria and cyanobacteria, a chain of vegetative cells; a cyanobacterial trichome is often surrounded by a slimy sheath.
Is Gloeocapsa unicellular?
For example, Gloeocapsa, colonial unicellular cocci-shaped taxa typically found on rocky coasts and also found in symbiotic relationships with fungi.
What is the difference between trichome and filament?
The key difference between trichome and filament is that trichome is a hair-like fine epidermal outgrowth seen on plants, while the filament is the stalk of a flower stamen that supports an anther.
