Are blue green algae cells prokaryotic or eukaryotic?

Cyanobacteria are prokaryotic cells that lack membrane-bound organelles and nuclei. Their common name is blue-green algae because of their blue-green color brought on by their pigment phycocyanin. Most algae are considered plants, but blue-green algae are bacteria.
A.

Is blue green algae unicellular?

Blue-green algae. Blue-green algae, also called cyanobacteria, any of a large, heterogeneous group of prokaryotic, principally photosynthetic organisms. Cyanobacteria may be unicellular or filamentous.
  • How old are the oldest bacteria fossils?

    However, one particular group of bacteria, the cyanobacteria or "blue-green algae," have left a fossil record that extends far back into the Precambrian - the oldest cyanobacteria-like fossils known are nearly 3.5 billion years old, among the oldest fossils currently known.
  • Is algae bad for you?

    Though many types of algae can form blooms, freshwater harmful algal blooms have the ability to produce toxins that are dangerous to other organisms such as humans, dogs, and livestock. While it is estimated that most blooms are toxic, it is difficult to predict exactly when or even if a bloom is producing toxins.
  • Are any cyanobacteria multicellular?

    They are classically separated into their various biological groups by their morphology; some groups are unicellular, others are multicellular and then there are those that can produce differentiation between cells. The morphologies of cyanobacteria (unicellular and multicellular taxa).
B.

Which kingdom does blue green algae belong to?

True bacteria
  • Is algae a phylum?

    Euglenophyta: small phylum of the kingdom protista, consisting of mostly unicellular aguatic algae. Some euglenoids contain chloroplasts with the photosynthetic pigments; others are heterotrophic and can ingest or absorb their food. There are approximately 1000 species of euglenoids.
  • Is Blue Green Algae autotrophic or heterotrophic?

    All other living organisms are eukaryotic, which have a membrane surrounding the nucleus. Monera (sometimes referred to as bacteria or blue green algae) are microscopic. They are either autotrophic or heterotrophic. An autotroph is an organism that can build its own food from "chemicals" like carbon dioxide and water.
  • What is the kingdom of algae?

    Some general biology textbook authors place the microscopic, unicellular green algae (Division Chlorophyta) in the Kingdom Protista, and place the larger, multicellular (macroscopic) green algae (Division Chlorophyta) in the Kingdom Plantae.
