Question

in the two - kingdom system, why were fungi classified in the kingdom plantae?
they are sedentary.
they are heterotrophs.
they lack cell walls.
they are unicellular.
they are autotrophs.

Explanation:

In the two - kingdom system (Plantae and Animalia), organisms were classified based on simple characteristics. Fungi were classified in Plantae mainly because they are sedentary (do not move from place to place on their own, similar to most plants). Heterotrophs (which fungi are) would classify them with animals in a two - kingdom system if that was the sole criterion. Fungi have cell walls (different from plant cell walls, but they have them). They can be multicellular (e.g., mushrooms) or unicellular (e.g., yeast). And fungi are not autotrophs (they do not produce their own food like plants via photosynthesis).

Answer:

They are sedentary.
