Friday 4/25– Biology Warm-up 1.The Herpes simplex virus is known for flaring out and creating sores on the lips and in the mouth during times of environmental stress. What reproductive cycle is happening when there are no flare ups? When there are flare ups? Learning Goal Understand and apply the classification system and differentiate between the kingdoms using physical and molecular evidence. Agenda Virus Models and Comic Strip Project Fungus notes Mushroom Dissection Lab

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  Most are saprophytes: they absorb and digest dead things.  Decomposers/recyclers  Some are Parasites  Digest their food outside of their body by secreting enzymes and absorb broken down organic matter  Fungi store energy in the form of glycogen.

Structure The body has tiny filaments called Hyphae. Hyphae: tiny tubes filled with cytoplasm, and nuclei. 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  Mold spores can cause mild to serious allergies  Fungi can infect and poison humans  Example: Valley Fever

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