What defining features are missing that prevent fungi from being included in thae plant kingdom?

Answer 1

One requirement for belonging to the plant kingdom is to have a cell wall made of cellulose. The cell wall of fungi is made of chitin. Most importantly, fungi lack chloroplasts and chlorophyll. Therefore, fungi do not perform photosynthesis like plants.

Primarily because it is not an autotroph, it can not make its own food as plants do and so is a herterotroph.

Also, it does not reproduce by seeds.

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.

Fungi are no longer classified as a type of plant. There were first considered part of the plant kingdom since fungi have many similarities to plants such as how they often are stationary and they both have cell walls. Now, fungi are known to actually more closely related to animals than to plants and are now classified in their own kingdom.

Fungi are not plants.

The part of the fungus that we see is only the "fruit" of the organism. The living body of the fungus is a mycelium made out of a web of tiny filaments called hyphae. The mycelium is usually hidden in the soil, in wood, or another food source.

Most fungi build their cell walls out of chitin. This is the same material as the hard outer shells of insects and other arthropods. Plants do not make chitin.

Fungi were previously included in the plant kingdom, but are now seen to be more closely related to animals. Unlike embryophytes and algae which are generally photosynthetic, fungi are often saprotrophs: obtaining food by breaking down and absorbing surrounding materials. Most fungi are formed by microscopic structures called hyphae, which may or may not be divided into cells but contain eukaryotic nuclei. Fruiting bodies, of which mushrooms are most familiar, are the reproductive structures of fungi. They are not related to any of the photosynthetic groups, but are close relatives of animals. Therefore, the fungi are in a kingdom of their own.

Fungi aren't plants for many reasons. The two main ones I can think of are;

• Fungi lack the multi-cellular nature of most plants. They are unicellular organisms, which often form long tendrils called mycelia, which allow the fungi to spread out before sporulating.
• Fungi have a cell wall made of a protein called chitin, as oppose to the cellulose (carbohydrate) cell wall of plants.

Answer 2

fungi do not need sun light to grow unlike plants. :)

fungi, unlike plants, do not photosynthesize and enough other differences exist between plants and fungi to separate kingdomd
