a scientist is studying the cells of an unidentified organism. which of the following observations would provide the strongest evidence that the organism is a fungus? (1pt)
a the cells are especially small, and they do not have nuclei or cell walls.
b the cells have cell walls that are made of chitin.
c the cells have a boxy shape, and they have cell walls made of cellulose.
d the cells have nuclei, but they do not have cell walls.

Explanation:

Fungi are eukaryotic organisms with nuclei, and their cell walls are uniquely composed of chitin. Option A describes prokaryotes (no nucleus, no cell walls like some bacteria). Option C describes plant cells (cellulose cell walls, boxy shape). Option D describes animal cells (nuclei, no cell walls). Only option B matches the key cellular feature of fungi.

Answer:

B. The cells have cell walls that are made of chitin.
