Why is algae not classified in the plant kingdom?

Answer 1

Who says they are? They both contain chlorophyll, they both perform photosynthesis...

wth... algae don't develop from multicellular embryos which are protected and noutished for a time by tissues of the parental plant, these are evolutions plants have. Both do have cellulose walls and, yes, chlorophyll.

Also algae are protists, protists aren't plants, and also mostly unicellular, some multi but not true tissues.

Answer 2

It really depends on the scientist your talking to, they share many similarities with plants and some deem them as plants because they are Eukaryotic organisms that create energy though the use of photosynthesis. Others still cling to the old Kingdom Chromista which died out right around the time that scientists choose to abolish the Protista kingdom. The last person to answer this question said it was a fungus because it grows on rocks and such, that is incorrect because the thing that makes a fungus a fungus is that they are decomposers who gain their energy through the breakdown and external digestion of other organic matter, since algae gains it's energy through photosynthesis that is not a correct deduction. There is also some cyanobacteria (photosynthetic bacteria) that some classify as a blue-green algae, they are not actually algae but share a similar outward appearance to algae like ankistradesmus that grow as a single celled organism.

Answer 3

Algae (like Kelp) lack tissue differentiation which means they have no viens (or vascular tissue).

Answer 4

Algae doesn't rely on soil during the photosynthesis process, so it is not in the plant kingdom.

Answer 5

Because algae have photosynthetic capabilities, protozoa generally do not (although this sometimes depends on who classifies them)

Answer 6

it is not plantae because algae is a single celled organism

Answer 7

Coz it is a fungi
