Telling the difference between living and non-living things is not always the easiest thing for some people. In science, there are general rules that scientists follow in order to determine if something is living or not. In order for something to be considered living it must observe all 8 of the following characteristics: movement, excretion, respiration, irritability, growth, reproduction, adaptability and nutrition.
Fungi is a living thing because it is able to move, respire, grow, reproduce, adapt to surrounding and eat.
(Movement) Fungi are the evolutionary champions of fast movement and use a variety of mechanisms to propel themselves into the air
(Respiration) They do cellular respiration because they are Heterotrophy. In other words, they cannot produce their own food. Cellular respiration usually happens in the mitochondrion of the cells.
(Growth & Adaptability) The growth of fungi as hyphae on or in solid substrates or as single cells in aquatic environments is adapted for the efficient extraction of nutrients, because these growth forms have high surface area to volume ratios.[48] Hyphae are specifically adapted for growth on solid surfaces, and to invade substrates and tissues
(Nutrition) Fungi are saprophytes. When they find a source of food, they decompose it and digest it. The enzymes break down larger organic molecules in the substrate into smaller molecules. These smaller molecules diffuse into the fungus, where they are used to allow growth and repair.
(Reproduction) Fungi can reproduce in two ways. Firstly, they make asexually produce through fragmentation. This occurs when pieces of hyphae are broken off, which then grow into new mycelia. The second method is by spores. Spores are lightweight structures and windblown designed to be transported over long distances and by many mediums, such as on the bodies of insects and birds.
