Kingdom Fungi Sections 18-2 and 23-2
A Recipe for Mushrooms Ingredients: Substrate (compost): hay horse droppings (urine,) corn cobs poultry droppings Spawn: mostly the mycelium of a mushroom
A Recipe for Mushrooms Directions: –Prepare the substrate: mix ingredients, sterilize –Combine spawn to substrate, mix –Wait then harvest mushrooms
Draw a mushroom Cap Stalk Hyphae: root-like fibers Mycelium: a group of hyphae Spores: inside gills
Examine a Mushroom Cap Stalk Gills Ring Basidia Spores
Cap Stalk Gills Basidia: inside gills, small Spores: attached to basidia Ring?
Nutrition Extracellular digestion Digestive enzymes are secreted into the substrate, digested food is absorbed into the mycelium.
Reproduction Haploid spores are produced The life cycle of a mushroom
1.The basidia are located in the gills. 2.The stipe is the stalk. 3.Haploid to diploid (n to 2n) 4.The germinating basidospore produces the the (hyphae?) or mycelium. 5.In the mycelium by fusion. 6.Basideospores are produced by meiosis. 7.Basideospres are dispersed by wind!

Lichens Green scale-like patches on rock and trees Symbiotic partnership –fungus (water, minerals) –cyanobacteria (photosynthesis) soil builders Survive in harsh environments
LICHENS- A primary producer
LICHEN Lichen is a combination of two separate organisms - fungus and cyanobacteria The fungus provides a structure that may protect the alga from drying and harsh conditions The algae provides the food supply using photosynthesis
In arctic and alpine regions such lichens as reindeer moss serve as food for caribou, reindeer and other mammals. Lichens are also dye sources, and is used as a food-coloring agent and to form litmus, the acid-base indicator.
Answer Key 1. Lichen is a symbiotic relationship between a fungus and a photosynthetic organism. 2. Because both partners benefit this is an example of mutualism. 3. Fungi can reproduce both __ sexually and asexually 4. The members of kingdom fungi are heterotrophic/heterotrophic they use other organisms for food. 5. The filaments that make up a fungus are called hypha. 6. Together these filaments are called the mycelium. 7. If the filament is an unspecialized root it is called a rhizoid. 8. The different phyla of fungi are separated based on their fruiting body, or spore-producing structure. 9. In bread mold, a sporangia is a structure that produces spores. 10. The fungus yeast is an exception, but most other fungi are multicellular, unlike the members of kingdom Protista. 11. In fungi, internal membranes, for example, a nuclear envelope, are present, making them eukaryotic, unlike the bacteria. 12. If an organism uses dead organisms as a food supply as many fungi do, it is called a saprophyte. 13. Athlete’s foot is a fungus that uses a living organism as a food supply. It is a parasite. 14. The outermost structure of a fungal cell, the cell wall, is different than plants. It contains a polysaccharide called chitin Fungi are important decomposers in the environment. Using extra cellular they breakdown dead organisms and release their nutrients into the environment. 16. After this process the fungi use absorption to obtain these nutrients. 17. A spore does not contain a double set of chromosomes. It is a haploid cell. 18. A single spore lands on a piece of bread and produces a sporangium and new spores. This is an example of asexual reproduction
