Is Oscillatoria eukaryotic or prokaryotic?

Nostoc and Oscillatoria are cyanobacteria; they are a group of photosynthetic and nitrogen-fixing bacteria, and Mycobacterium comes under true bacteria. Therefore, Nostoc, Oscillatoria, and Mycobacterium are prokaryotes.

What color are the cells of the Oscillatoria colony?

Filaments in the colonies can slide back and forth against each other until the whole mass is reoriented to its light source. It is commonly found in watering-troughs waters, and is mainly blue-green or brown-green.

What is the cell structure of Oscillatoria?

Oscillatoria limosa Agardh., is a filamentous alga with trichomes ranging from 2 to 6 ;u in diameter. Each cell is approximately 2n thick. Cells are arranged in the filament as a series of short discs, or very like a stack of “poker chips.” The end wall of the apical cell of the filament is usually convex.

Do all cells of Oscillatoria look similar?

Oscillatoria Morphology The cells are broader than longer but cylindrical. All cells of a filament are similar with the exception of apical cell which is convex at the top. ln some species it may end in a subacute point or be more or less dilated, or capitated having a thickening known as a cap or calyptra at the tip.

Which does a prokaryote not have?

Prokaryotes are organisms whose cells lack a nucleus and other organelles. The absence of a nucleus and other membrane-bound organelles differentiates prokaryotes from another class of organisms called eukaryotes.

Is true nucleus is absent in Volvox?

Volvox is a eukaryotic green algae. Despite their name, these algae are actually a colony of bacteria capable of photosynthesis. They belong to cyanobacteria. Anabaena Like other prokaryotes, lack a true nucleus and other cell organelles.

Is bacterial DNA in a nucleus?

The bacterial genome is composed of a single molecule of chromosomal deoxyribonucleic acid or DNA and is located in a region of the bacterial cytoplasm visible when viewed with an electron microscope called the nucleoid. Unlike the eukaryotic nucleus, the bacterial nucleoid has no nuclear membrane or nucleoli.

What kind of cell structure does an Oscillatoria have?

Cell Structure 4. Reproduction 5. Movement. Oscillatoria, a fresh water, blue green alga, is represented by 76 species. Species are commonly found in fresh and polluted water of ponds, pools, drains, streams, and also in damp soils and rocks. These form bluish scums on water surface or at pond-bottom.

Where can I find an Oscillatoria alga?

Oscillatoria, a fresh water, blue green alga, is represented by 76 species. Species are commonly found in fresh and polluted water of ponds, pools, drains, streams, and also in damp soils and rocks. These form bluish scums on water surface or at pond-bottom. O. princeps grows in sea water and sub-aerial habitats.

How many species of Oscillatoria are there?

Oscillatoria, a fresh water, blue green alga, is represented by 76 species. Species are commonly found in fresh and polluted water of ponds, pools, drains, streams, and also in damp soils and rocks. These form bluish scums on water surface or at pond-bottom.

Where can I find an Oscillatoria cyanobacterium?

Oscillatoria. Oscillatoria is a genus of filamentous cyanobacterium which is named after the oscillation in its movement. Filaments in the colonies can slide back and forth against each other until the whole mass is reoriented to its light source. It is commonly found in watering-troughs waters, and is mainly blue-green or brown-green.
