Actually, fungi have many complex ways to obtaining nutrients. Some are saprophytic and can grow on and digest dead things or organic matter which it uses as a food supply. An example is a shelf fungus that grows on the side of a dead tree, or mushrooms that grow on cow manure, or mold that grows on an old book in the basement. Fungi can be part of a mutual relationship as in lichens, which are both fungi and algae that live together in a close nutritional relationship. In this case, algae make food via photosynthesis and the fungi uses some of it, while providing the algae a place to grow. Fungi can be parasitic as in yeast infections or athlete's foot fungus, when they grown on or in another organism, gaining their nutrients from the host. However, because they don't convert sunlight energy to chemical energy, they are definitely not producers, nor plants.
No, fungi are not plants. They are not even members of the same biological kingdom. They are each separate kingdoms (Plantae for plants, Fungi for fungi) within the same domain (Eukaryota).
The major difference between the two is that plants can make their own food through photosynthesis. Fungi can't -- they tend to be parasitic and live off a host.
Definitely no, fungi are not plants!
Let's see why:
First of all, fungi cannot make their own food, like plants are making. For fungi, it is vital to rely on other food sources. We know that plants are producing their own food, using sunlight.Another difference between fungi and plants is represented by the chemistry of their cells.
