Many infected animals are induced by the parasitic microsporidians to develop huge cells, known as xenomas, which are full of spores. Given their large size, what should be true of the xenomas?
A) The parasite must endow the xenoma with some way to overcome its unfavorable surface area-to-volume ratio.
B) The xenoma must obtain mitochondria to survive.
C) The xenoma must gain a cell wall; otherwise, it will lyse.
D) The xenoma acts as a prison, of sorts, to keep the spores from escaping and infecting other organisms.
Terrestrial plants and animals can be characterized by analogous pathways for water gain and loss.
