Ateacher says she has identified an organism with these characteristics: eukaryotic, multicellular, autotrophic, and a cell wall made of cellulose. which kingdom is the teacher describing?
animalia
protista
plantae
eubacteria

Answer : The correct answer is -

Third option- Plantae.

As per the given information in the question, an organism was identified by the teacher with the characteristics: eukaryotic, multicellular, autotrophic, and a cell wall made of cellulose.

Organisms belonging to Plantae kingdom are eukaryotes (that is contain true nucleus and membrane bound subcellular compartments, called cell organelles).

They have cell wall (primarily composed of cellulose) around their cell membrane.

They are multicellular organisms (as composed of many cells) and considered as autotrophs (synthesise their own food through photosynthesis).

Thus, the teacher is describing Plantae kingdom.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
