Why are fungi and plants in different kingdoms?

Answer 1

Fungi have cell walls composed of chitin instead of cellulose (usually). Fungi also lack chloroplasts and are therefore unable to perform photosynthesis. Fungi use the AAA pathway to synthesize lysine instead of the DAP pathway used by plants. Plants have multiple flagella on their motile spores while fungi only have one. The closing evidence are molecular phylogenies, which pretty consistently group fungi with animals on the tree of life.

Answer 2

Both are eukaryote organisms, but plants use photosynthesis to produce their food and fungi are consumers of detritus and do not produce their own food. This is a simple but profound difference between the kingdoms.

Answer 3

Fungi are classified in a separate kingdom from plants because they have different cell wall compositions (fungi have chitin in their cell walls while plants have cellulose), obtain nutrients differently (fungi are heterotrophic while plants are largely autotrophic), and have distinct modes of reproduction (fungi reproduce through spores while plants use seeds).

Answer 4

Fungi doesn't have chlorophyll. Plants do have chlorophyll.

Answer 5

Because fungi do not make their own food as plants can do. They are detritavores, saprophytes, that ingest detritus on forest floors and dead matter everywhere.

Answer 6

Fungi are saprophytic (decompose dead matter), that is how they get their food. Plants are autotrophic (make their own food), they produce their own food with photosynthesis.

Answer 7

Mushrooms are characterized as fungi, not plants. Mosses are considered plants.
