2Fungi Basics Heterotrophs Cell composition similar to animals Cannot perform photosynthesisRelease enzymes to absorb nutrientsCell composition similar to animalsReproduction: Sexual & AsexualClassified by how they reproduce
3Comparing Plants & Fungi Plants and fungi have different traits:Fungal cell walls are made of chitin.Plant cell walls are made of cellulose.Plants have chlorophyll and photosynthesize.Fungi absorb food through hyphae.Plants and fungi have similar traits:Both are nonmoving.Grow underground and aboveground.May produce spores.
4Fungi Structure What grows underground? Hyphae: thin strands of cells that make up the fungus bodyHyphae branch into a larger mass (mycelium)What grows above ground?Fruiting body: reproductive structure creates spores
5Bread Mold Fungi Bread molds Get name due to ability to create zygosporeProtective spore surrounding the zygoteSpores produced inside sporangia (sporangium)Spores released into air
6Club Fungi . . . . Mushrooms, puffballs, shelf fungi Fruiting body looks like clubSpores produced in structures called basidia (basidium)Spores released into air....Grassy ground
7Sac Fungi Yeast Single celled Reproduce asexually through budding Morels, trufflesFruiting body resembles a sacSpores produced in structures called Asci (ascus)Spores released into air
8Reproductive Structures of Fungi (that you need to know)
10Spores will landFungus #1 mycelium grows underground….Fungus #2 mycelium grows undergroundTwo fungi grow together and fuse…new mycelium created.Fruiting body sprouts.New spores released from the fruiting body.....ground
11Lichens Fungus + algae or cyanobacteria Mycelium of fungi surrounds the green organismGrow on rocks, soil, treesMutualistic relationshipAlgae/bacteria: obtains home to grow within; gets waterFungus: obtains nutrients
12REview Name the three major types of fungi. Which characteristic is used to classify the various types of fungi?Which fungi produce asci?Which fungi produce basidia?Which fungi produce zygospores?What is the above ground structure of a fungus called?What objects are released from the fruiting body?Label the diagram.
