Does an organism exist that is both plant and animal?

Question

what is it that defines the difference between plant and animal?

Answer 1

Micro-organisms called euglenas are such. They can feed on other animals and plants to obtain nutrients, or they can photosynthesize on their own to produce nutrients. They are more dependant on neither.

Answer 2

No

They either have plant cells or animal cells, and the cells differ in quite some ways....

etc, animal cells dont have a cell wall thats why skin is *flexable*
also plant cells have a large vacoule...usually contains water, and thats why when u bit down on plant stuff,you hear the crunch...its you breaking the vacoule

So The answer is basically no

Answer 3

No, they are very different at the cellular level. At the very basic level, plants have cell walls and rely on turgor pressure, provided by a hypotonic solution, to keep their shape. Animals cells, have no cell walls and would burst if surrounded by a hypotonic solution. Plants are also autotrophs (self-feeders) while animals are heterotrophys (subsist on other organisms). Plants use photosynthesis, fixate carbon into sugars, and release oxygen as a waste product, while animals break down sugars and release CO2.

So in essence, it is quite impossible.

edited for Omar D: euglenas are protists, and as such, are neither plant nor animal.

Answer 4

At the level of microorganisms, it gets pretty vague. Some critters are more really plants; some plants more really critters. But beyond the most primitive life forms, the division is pretty obvious, because plants have an extra layer of cell wall around their cells.

Answer 5

"Which organisms came first on the earth, simple plants, or simple animals?" As far as is known, both plants and animals evolved at much the same time. "Plants create their own food, animals obtain food from the others" Plants don't "create their own food". More importantly, there are loads of organisms around which are neither plants or animals, and the origin of most those lineages pre-date that of both the groups you specified. "this site and my proffessor tells that it is likely that bacteria-like organisms came first, eating other amino acid rich organisms, so the first symbiosis done is predation." Yes, and they're neither plants or animals.

Answer 6

no. There are animals that does photosynthesize, but it's still animal.(a slug who eats algae and steel the chlorophyl) The closest thing are symbiants like coral. Coral is an animal, Algae enters the coral for protection, and the algae offer food to the coral. There are Jellyfish like that too. It even move to a sunnier location for the algae.

Answer 7

yeast i think its not clear if its a plant or an animal

animals have the power of locomotion

Answer 8

yes euglena

Answer 9

no,not yet anyway
