question 30

Multiple Choice

Use the following information to answer the questions below.
Trichoplax adhaerens (Tp) is the only living species in the phylum Placozoa. Individuals are about 1 mm wide and only 27 μm high, are irregularly shaped, and consist of a total of about 2000 cells, which are diploid (2n = 12) . There are four types of cells, none of which are nerve or muscle cells, and none of which have cell walls. They move using cilia, and any "edge" can lead. Tp feeds on marine microbes, mostly unicellular green algae, by crawling atop the algae and trapping it between its ventral surface and the substrate. Enzymes are then secreted onto the algae, and the resulting nutrients are absorbed. Tp sperm cells have never been observed, nor have embryos past the 64-cell (blastula) stage.
-In its native environment, a Tp cell neither gains nor loses water. What should one expect to occur when Tp is placed into fresh water?

• A)No change, as fresh water is its native environment
• B)lysis
• C)plasmolysis
• D)slight shrinkage
