Blue-green algae are colored prokaryotes that can be unicellular or can form colonies of cells, but they are not truly multicellular. this algae species is autotrophic, needs sunlight, and performs photosynthesis.
are blue-green algae plants?
a. yes, because they are not multicellular or eukaryotic
b. yes, because they are autotrophic and need sunlight
c. no, because they are autotrophic and need sunlight
d. no, because they are not multicellular or eukaryotic

Blue-green algae are not multi-cellular or eukaryotic.

D

Explanation:

The most prominent characteristic feature of an organism to be placed in plant kingdom is that the organism must be a multicellular in its cellular arrangement and should be a eukaryote and must possess various membrane bound cell organelles.

Though the blue green algae has the ability to prepare its own food as it is autotrophs,  it cannot be considered as plants because the blue-green algae are unicellular and are prokaryotes  in nature.

d. no, because they are not multi cellular or eukaryotic.

Explanation:

Blue-green algae are prokaryotic. They are basically Cyanobacteria. They can photosynthesise on their own. But all plants are Eukaryotas. Even though they can also photosynthesise like plants, they are unicellular.

Which means they lack certain eukaryotic cellular features. Thus, Plants in general are autotrophs but all autotrophs are not plants.

the correct answer is c   with the systems
