The Fungi Kingdom September 19th, 2024 Plans Monday Tuesday Wednesday Thursday Friday 16 17 18 19 20 Plants Fungi Microscope Lab Day 23 24 25 26 27 Animals Review Day I am away Unit #1 Test + + Start Review Picture Day Tomorrow: Microscope Lab We will meet in room 221 Learning Goals Understand characteristics that are unique to fungi and how they are different from bacteria, archaea, plants, and protists Know the different structures that make up fungi Understand the different ways in which fungi can reproduce Recognize the different ways in which fungi obtain nutrition Fungi Kingdom Fungus: a stationary, heterotrophic eukaryotic organism whose cell walls contain chitin - Kingdom contains unicellular and multicellular species - Multicellular species can be generalized as in the image below. Fungi Kingdom Hyphae: multicellular, thread-like filament that makes up the basic structural unit of a fungus Mycelium: a continuation of hyphae that extends below ground for attachment Fruiting Body (aka Cap): spore-producing reproductive structure Fungal Nutrition UNIT 1 Chapter 3: Multicellular Diversity Section 3.3 Fungal Nutrition Fungi release enzymes that break down Fungi release enzymesfood that break externally, then they absorb nutrients fromthen down food externally, thethey absorb nutrients from the food food through their cell membranes through their cell membranes. There are four different ways in which Four ways fungi obtain nutrients: fungi can obtain nutrients… 1. Parasitic 1. Parasitic 2. Predatory 2. Predatory 3. Mutualistic 3. Mutualistic 4. Saprobial (feeding off dead organisms or organic waste). 4. Saprobial (feeding off dead organisms or waste) Fungal Reproduction Asexual Budding: small cell develops while attached to a parent cell, eventually pinches off Asexual Fragmentation: a piece of mycelium breaks off and forms a new individual Sexual Reproduction: involves the production of spores Fungi Classification (don’t copy) Fungi are classified based on… 1. Whether reproduction is sexual or asexual 2. On the structure of the fruiting body There are five phyla… Fungi Phyla Fungi Imperfecti: includes all fungi that do not reproduce sexually. It has been used as a source for pharmaceuticals Chytrids: organisms that are mostly unicellular and aquatic. They are parasitic or saprobial Zygospore: multicellular and mostly terrestrial. They include food moulds and reproduce asexually but can also perform a type of sexual reproduction Fungi Phyla Sac Fungi: develop small, finger-like sacs called asci during sexual reproduction Club Fungi: organisms include mushrooms and puffballs. Fruiting bodies release spores called basidiospores from specialized hyphae called basidia Homework Read pg 80 - 85 Watch https://youtu.be/m4DUZhnNo4s?si=4q3NIvYE5wRsRp5A https://youtu.be/m4DUZhnNo4s?si=4q3NIvYE5wRsRp5A Watch (Scary!) https://youtu.be/XuKjBIBBAL8?si=53rYYYiNAZFG_piG https://youtu.be/XuKjBIBBAL8?si=53rYYYiNAZFG_piG
