Oxygen comes out as waste product in plants during photosynthesis
kidneys
Yes.Another Answer:Whether vomit is an excretion is something of an opinion (semantic) question. The definition of an excretion is a waste product, so since vomit is nt a biological waste product, by that definition vomit would not be an excretion and, by extension, vomiting would not be excreting.
excretion
The primary by-product of protozoan excretion is ammonia
Excretion is removing waste product from your body. Humans excrete either through their pores (sweating) or through faeces (going to the toilet).
Many people confuse the process of excretion with the removal of waste products of digestion. Excretion, however, is actually the removal of all the waste products produced by the cells of the body.

The removal of waste products from the body is called excretion
Waste from plants is in the form of oxygen that is produces as a by product of photosynthesis; some plants (such as soy beans) waste nitrogen back into the soil as well.
