How does the Fuligo Septica obtain food?

They exist in a nature as a plasmodium, a blob of protoplasm without cell walls and only a cell membrane to keep everything in. It is really nothing but a large amoeba and feeds much the same way, by engulfing it’s food (mostly bacteria) with pseudopodia... the plasmodium of Fuligo Septica is transparent, like an egg white.

The answer is c the potato slice shriveled because water moved out of the slice into the salt solution
