Cell: The Basic Unit of Life — NEET Biology
📚 Practice ConceptWhen you look around, you see both living and non-living things. You must have wondered and asked yourself – 'what is it that makes an organism living, or what is it that an inanimate thing does not have which a living thing has'? The answer to this is the presence of the basic unit of life – the cell in all living organisms.
A scientist isolates a new unicellular organism that survives independently in freshwater and shows the presence of naked DNA without a nuclear membrane, but also demonstrates mesosome-like structures for respiration. Which combination of cell theory and cellular features best explains this organism?
View solution & NCERT explanation
Correct answer: B — Fundamental unit of life is the cell + prokaryotic organisation with mesosomes
Unicellular organisms are capable of independent existence and performing essential functions of life. There is no well-defined nucleus. The genetic material is naked… A specialised differentiated form of cell membrane called mesosome is the characteristic of prokaryotes.
