A channel protein serves as a tunnel across the membrane into the cell. More specifically, channel proteins help molecules across the membrane via passive transport, a process called facilitated diffusion. These channel proteins are responsible for bringing in ions and other small molecules into the cell
Answer:
By the structure of their cell wall
Explanation:
Fungus cell contain cell wall with a chitin in it. That differs them from animal cell that doesn't have cell wall, but also differs them from plant cell wall which contains cellulose.
Fungus is a eukaryotic kingdom which contains microorganisms such as yeasts and molds, but also macroscopic forms such as mushrooms.
Fungus are heterotrophic organisms, often decomposers with high biodiversity.
