Organisms classified as fungi have unique characteristics. Which of the following characteristics is found only in organisms classified in the kingdom fungi?
A. single cells without a nucleus
B. multicellular with chloroplasts
C. multicellular filaments that absorb nutrients
D. colonies of single, photosynthetic cells that reproduce asexually
What is C. multicellular filaments that absorb nutrients
These filaments, called hyphae extend into the fungi’s food source and absorb nutrients. Fungi are not able to make their own food.
