Fungi By: Danielle Noe
What is Fungi? • Fungi is a group of plants that have no chlorophyll. Some fungi have single celled organisms and some are multi-cellular. There are many types of fungi.
Structure and Function • Hyphae: Main body, madeof fine, branching, colorless threads. • Mycelium: Each fungus has many hyphae all intertwining to make up this usually to small for the human eye. • Septa: cross walls dividing cells of mycelium. • Filamentous: They have a filamentous cell structure. (Fine, thin, string like) • Chitin: They have chitin cell walls rather than cellulose.
Matter and Energy Flow • Cellular Respiration: Bacteria and fungi eat on the decomposing animal or plant and get nutrients from it. They then use the energy and release carbon dioxide into the atmosphere. • Photosynthesis: Since fungus grows from the ground they are nonphotosynthetic plants.
Matter and Energy Flow • How does it live? • Fungi eats on dead organic matter or grows on other organisms to get nutrients for growth. • Where does fungi live? • Fungi can be found in many different environments and will grow on almost anything. • Example: On your feet (Athlete’s foot), can cause ring worm, and on many foods.
Osmosis • Osmosis: Osmosis is important in growth- entry of water forces it to extend at the tip. It enters through pores on the lower surfaces which are not covered by a cuticle. • Absorption of water by plant roots
Diffusion • Diffusion: Diffusion is important because fungi decomposes organic wastes and remains of dead plants so diffusion helps by returning nutrients such as nitrogen back to the soil.

Fun Facts! • The Kingdom Fungi has over 100,000 species. • Each cell has 1 or 2 nuclei. • It is one of the five kingdoms of organisms because it is closer to animals than plants. • Study of fungi is called mycology. • Fungus is not dependant on light and can grow in any directions.
Fun Facts! • Fungi does not digest their food. • They digest food outside of their body and absorb it. • Some live as parasites. • Most fungi reproduce by spores. • Fungi are classified into 3 groups based on their sexual reproductive structures. • Some are helpful to humans.
