Are single celled organisms considered as plants or animals?

Question

I need this for my zoology report. :((

Answer 1

They aren't considered to be either plants or animals.

Some such as amoebas engulf their food. Some such as algae can make their own food.

Single celled organisms are bacteria, Archaea, protists, fungi..

Answer 2

Single Celled Plant

Answer 3

When I was a child, Life had only 2 Kingdoms: Plantae and Animalia. Some single celled organisms were classified as Plants and some as Animals. Sometime, this changed. Now there are 5 Kingdoms: Monera, Protista, Fungi, Plantae, and Animalia. Single celled organisms are divided among the Monerans, Protists, and Fungi. All Plants and Animals are multicellular.
For more info, look 'em up.

Answer 4

You lack a basic understanding of the evolutionary process. Instead of being skeptical, why don't you investigate the scientific literature to find out what you want to know. However, don't look for answers in the creationist literature. They lie. To give a short answer to your question, single celled organisms did not mutate to sexual forms. In the process of evolution, some single celled species formed colonies. Over time, some of the cells within a colony became specialized to perform certain functions--for example, to draw food into the colony or to expel waste from the colony. Over time as more and more of the cells became specialized, the colony became a primitive multi-celled organism. Sponges are examples of this process. Over more and more time the primitive multi-celled organisms evolved further and into more advanced organisms that were no longer colonies of cells, but rather individual organisms. Sexual development was also a gradual process. There was no need for it to occur many times. Once it was established, it continued as part of the natural reproduction process.

Answer 5

Some single cell entities are plants, some are animals.
The difference is in the cell walls.

Answer 6

Then you need to do the research on your own.

But here's a clue...Sometimes. Look at Algae & Protozoa then do a review of the other 3 phylogenetic kingdoms and you'll have an even better clue.

Answer 7

neither they b'long to plants nor to animals ..
they belong to protozoans categories ..
all the single celled organisms are grouped under protozoa.........

Answer 8

some scientists say plants and some say animals and then others say niether...so nobody really knows for sure...
