Question
In 1888, Leo Errera theorized that cells in this kingdom divide like a soap bubble, minimizing the surface area of the cell plate to form the shortest symmetric path. For 10 points each:
[10e] Name this kingdom of eukaryotes that have cell walls made of cellulose.
ANSWER: plants [or Plantae]
[10m] The soap bubble theory fails in the “apical” type of this undifferentiated plant tissue, since cells in it divide longitudinally to grow the tips of the shoots or roots.
ANSWER: meristem [accept apical meristem or root apical meristem or stem apical meristem; reject “lateral meristem”or “cambium”]
[10h] By contrast, animal cells usually divide down their longest axis due to the activity of this family of motor proteins. These proteins move cargo down microtubules toward the nucleus, in the opposite direction as kinesins (“kye-NEE-sins”).
ANSWER: dyneins
