Solution
The correct option is B Plasmodium
Plasmodial slime molds exist as a mass of amoeba-like protoplasm, (called a plasmodium) that contains many nuclei within a single cell membrane. Plasmodial slime molds, like Physarum, are basically enormous single cells with thousands of nuclei. They are formed when individual flagellated cells swarm together and fuse. The result is one large bag of cytoplasm with many diploid nuclei. These "giant cells" have been extremely useful in studies of cytoplasmic streaming (the movement of cell contents) because it is possible to see this happening even under relatively low magnification. In addition, the large size of the slime mold "cell" makes them easier to manipulate than most cells. Thus the correct answer is option B.
