There are three reasons why a Fungus is not a Plant.

In the 1960s, fungi were considered plants.Unlike plants, fungi do not have the green pigment chlorophyll, which makes them incapable of photosynthesis.They can't use energy from light to make their own food.

How can fungi survive without a chloroplast?The energy stored in organic compounds can only be used by Fungi.This distinguishes plants from fungi.The osmotrophic nature of fungi is similar to that of animals.The vitamins and minerals are absorbed by the entire body.

Plants use the process of photosynthesis to make their own food.Fungi get their food from the plants they are attached to.Green chlorophyll is not found in fungi.The cell walls of plants are made of cellulose, while the capsule of fungi is made up of chitin.

They are different from plants in two ways, one of which is that they do not make their own food.They are mammals.They eat off their hosts as parasites to get their food.
