probably most likely grass..............or algae because they give off most of the worlds oxygen....so grass or algae

Algae are plants.
Nearly all plants, as well as algae, create oxygen. In fact, all plants and algae that make their own food from sunlight, air, and water do produce oxygen. Two my knowledge, there are only a couple of types of parasitic plants that get food from other plants, and thus do not make their own food or oxygen.
Algae are plants.
this question means give me the examples of unicellular plants
Plants give off oxygen in which humans live off. And in return humans give off carbon dioxide in which plants live off.
Tadpoles eats little plants in the water called Algae
The major difference between plants and algae is that plants have connective tissues for the transportation of water in the entire plant body while every cell of algae absorbs water from the source on its own. There is no connective tissue is algae. Secondly, the reproduction system of plants is more developed while that of algae is primitive. Thirdly, algae can be single-celled while plants are multicellular organisms. Another area of difference between plants and algae is photo respiration. Moreover, it is argued by the scientists that algae and plants may share the same ancestor but algae cannot be classified as plants.
Most leafy plants and trees give off oxygen
They do not have roots, stems, or leaves Edited answer: Algae come under primitive plants as these ahve varity of forms ranging from unicellular to multicellular colonial and filamentous and have undifferentiated body.
No, because plants are not made up of algae
