Multiple Choice

Use the following information to answer the question.
For the past several decades, 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. Chytrid sporangia reside within the epidermal cells of infected animals, animals that consequently show areas of sloughed skin. The infection cycle typically takes four to five days, at the end of which zoospores are released from sporangia into the environment.
Apart from direct amphibian-to-amphibian contact, which of the following is responsible for the movement of zoospores from one free-living amphibian to another?

• A) wind-blown spores
• B) flagella
• C) cilia
• D) hyphae
