Fungi

Fungi Basics Eukaryotic, Nonphotosynthetic Organisms Most are Multicellular Heterotrophs. Have nuclei and mitochondria Many fungi are microscopic Molds: tangled masses of filaments of cells Yeast: unicellular, colonies are similar to bacteria

Fungi Nutrition All fungi are heterorophs, Most are saprophytes: they absorb and digest dead things. Decomposers/recyclers Some are Parasites Fungi Digest their food outside of their body by secreting enzymes that break down organic material. They then absorb the food through their cell walls. Fungi store energy in the form of Glycogen.

Structure The body has tiny filaments called Hyphae. Hyphae: tiny tubes filled with cytoplasm, and nucli. The cell wall has chitin which in unique to fungi. Mycelium: Mass of tangled, interwoven Hyphae the body)

Reproduction They use asexual reproduction when they have more then enough food and water Mitosis, budding, fragmentation, or spores Spores are a fungi’s way of traveling. One cell that can reproduce into a new individual

Reproduction They use sexual reproduction when food and water are scarce Fertilization: Hyphae - a Plus Mating Type and a Minus Mating Type Fuse. Specialized structure form that produces and scatters genetically diverse spores.

Fungi and Disease Fungal disease make us sick and contaminate our food Mold spores can cause mild to serious allergies Fungi can infect and poison humans

Contributions of Fungi Foods we eat Medicine Recycling dead organisms back into the environment.
