4. Basic Structure of Fungi Hyphae – basic structural units of multicellular fungi,Hyphae – basic structural units of multicellular fungi, filled with cytoplasm and nucleifilled with cytoplasm and nuclei Septa – cross walls of hyphae (divided into individual cells)Septa – cross walls of hyphae (divided into individual cells) http://www.earthlife.net/lichens/images/hyphae.jpg http://images.suite101.com/592160_com_hyphae_and.jpg

5. Adaptations of Fungi Can be harmful –Can be harmful – –Food spoilage –Disease in humans and plants – ex. athlete’s foot, ringworm, thrush & Dutch Elm disease Thrush http://www.medical-look.com/diseases_images/oral-thrush2.jpg http://images.google.com/imgres?imgurl=http://apps.rhs.org.uk/advice/ACEImages/SCN00005 31_175327.jpg&imgrefurl=http://apps.rhs.org.uk/advicesearch/Profile.aspx%3Fpid%3D154&usg =__bRRT8HwfF1BSvYyw4By2CAIcRxM=&h=432&w=288&sz=106&hl=en&start=7&itbs=1&t bnid=HrrPVzoZkvR4AM:&tbnh=126&tbnw=84&prev=/images%3Fq%3Ddutch%2Belm%2Bdis ease%2Bfungus%26hl%3Den%26safe%3Dactive%26sa%3DN%26gbv%3D2%26ndsp%3D20%2 6tbs%3Disch:1 http://www.ourhealthnetwork.com/UserFiles/Image/Athletes_foot_Pict_Plantar_2%281%29.jpg

6. Can be helpful – –as decomposers they break down a huge amount of waste and return nutrients to the soil. –forms symbiotic relationships with autotrophs (ex. Lichens are fungi and photosynthetic bacteria) http://upload.wikimedia.org/wikipedia/commons/0/0d/Lichens_Tree_Clairmarais.jpg http://www.pharma.unibas.ch/bio/img/Research/penicillin_g_sm.jpg

7. Can be helpful – –They help make important medicine, including antibiotics – for example the Penicillium mold produces the chemical penicillin that we use as an important antibiotic http://upload.wikimedia.org/wikipedia/commons/0/0d/Lichens_Tree_Clairmarais.jpg http://www.pharma.unibas.ch/bio/img/Research/penicillin_g_sm.jpg

8. How Fungi Obtain Food Heterotrophs – Will obtain nutrients from some other food source.Heterotrophs – Will obtain nutrients from some other food source. Decomposers – Break down substances & obtain nutrients through extracellular digestion.Decomposers – Break down substances & obtain nutrients through extracellular digestion. Extracellular Digestion – secrete enzymes on some other organism, the enzymes break down the organism, then the fungi will obtain nutrients by absorption.Extracellular Digestion – secrete enzymes on some other organism, the enzymes break down the organism, then the fungi will obtain nutrients by absorption.

9. Reproduction in Fungi Asexual reproduction – by fragmentation, budding, or sporesAsexual reproduction – by fragmentation, budding, or spores Sexual reproduction – exchanging genetic materialSexual reproduction – exchanging genetic material http://www.mobot.org/gardeninghelp/images/Pests/Pest800.jpg
