Which feature seen in chytrids supports the hypothesis that they diverged earliest in fungal evolution? -
CORRECT ANSWER flagellated spores
For several decades now, amphibian species worldwide have been in decline. A significant proportion of
the decline seems to be due to the spread of the chytrid fungus, Batrachochytrium dendrobatidis (Bd).
Chytrid sporangia reside within the epidermal cells of infected animals, animals that consequently show
areas of sloughed skin. They can also be lethargic, which is expressed through failure to hide and failure
to flee. The infection cycle typically takes four to five days, at the end of which zoospores are released
from sporangia into the environment. In some amphibian species, mortality rates approach 100%; other
species seem able to survive the infection.
