Friday 4/25– BiologyWarm-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 GoalUnderstand and apply

the classification system and differentiate between the kingdoms using physical and molecular evidence.

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.
