Practice questions testing deep understanding of organelle function, membrane models, and cell structures.
Q1. The Fluid Mosaic Model describes the cell membrane as a "fluid" structure rather than a solid, rigid wall. What specific biological activities of the cell are made possible only because the membrane is fluid and flexible? Mention at least two.
Q2. Both mitochondria and chloroplasts are unique organelles because they are "semi-autonomous." What specific structural features do they possess that give them this title, and what evolutionary theory explains this?
Q3. Assertion (A): Ribosomes are the only organelles found in both eukaryotic (human) cells and prokaryotic (bacterial) cells. Reason (R): Ribosomes are not enclosed by any lipid membrane. Since prokaryotes lack all membrane-bound organelles, non-membranous ribosomes can exist within them to synthesize essential proteins.
