Like clockwork, every 90 years cell biologists re-discover liquid–liquid phase separation. For 10 points each:
[10m] This phase-separated compartment of a larger membrane-bound organelle was first discovered in the 1830s. It is where cells synthesize rRNA.
ANSWER: nucleolus [reject “nucleus”]
[10h] In the 1920s, biologists stumbled upon phase separation to explain how plant cells concentrate starch in these liquid compartments. Platelets are chock-full of the “dense” and “alpha” type of these compartments, which also lend their name to a class of white blood cells including neutrophils.
ANSWER: granules [or starch granules; or dense granules or alpha granules; or granulocytes]
[10e] Biologists in the 2010s were re-infatuated when they found droplets of RNA can phase-separate from this gel that fills the space between organelles.
ANSWER: cytoplasm [or cytosol]
