Question
In 2023, Will Ratcliff’s lab evolved “snowflake yeast” with this trait to grow 20,000 times bigger than wild-type yeast. For 10 points each:
[10m] Name this property possessed by all fungi except yeast. When food is scarce, slime molds switch to this trait and form fruiting bodies.
ANSWER: multicellularity [or having more than one cell; accept synonyms; prompt on multinuclear or having more than one nucleus or synonyms]
[10h] The size of single cells is capped by the need to keep this parameter above an inverse-micron. Allen’s rule says this ratio is smaller for animals in cold climates.
ANSWER: surface area-to-volume ratio [or the ratio between surface area and volume; or SA over V; accept either order of those two terms, like volume-to-surface area ratio; accept surface area-to-mass ratio or mass-to-surface area ratio; prompt on surface area or area by itself; reject “volume” or “mass” or “body mass” or “size” or “body size” by itself]
[10e] A really long single cell is impractical because it imposes too much stress on this cellular network of microfilaments and microtubules. Analogous to human bones, this structure provides shape and support to the cell membrane.
ANSWER: cytoskeleton
