Why Is A Mushroom Not A Plant

As a mushroom enthusiast and expert, I often encounter the misconception that mushrooms are a type of plant. However, this is not the case. Mushrooms actually belong to their own unique kingdom called Fungi. In this article, I will delve into the reasons why mushrooms are not considered to be plants.

Mushrooms Belong to the Fungi Kingdom

One of the key reasons why mushrooms are not classified as plants is because they belong to the kingdom Fungi, distinct from the plant kingdom. Fungi have their own unique characteristics and biological structure that differentiate them from plants. While plants produce their own food through photosynthesis, fungi obtain nutrients through absorption. This fundamental difference sets fungi, including mushrooms, apart from the plant kingdom.

Mushrooms Lack Chlorophyll

Another important factor that distinguishes mushrooms from plants is the absence of chlorophyll. Chlorophyll is a pigment found in plants that enables them to carry out photosynthesis, the process through which they convert sunlight into energy. In contrast, mushrooms lack chlorophyll and therefore cannot perform photosynthesis. Instead, they obtain nutrients by decomposing organic matter in their environment.

Cell Wall Composition

The composition of the cell wall also sets mushrooms apart from plants. While plant cell walls are primarily made of cellulose, the cell walls of fungi, including mushrooms, are composed of chitin. This structural difference further emphasizes the unique biological characteristics of fungi and distinguishes them from plants.


In conclusion, it is evident that mushrooms are not classified as plants due to their distinct biological characteristics, belonging to the kingdom Fungi, the absence of chlorophyll, and the composition of their cell walls. Understanding the differences between mushrooms and plants is not only fascinating but also essential for appreciating the diversity of life on our planet.
