  1. SEENED Leelo Lusik Are PK 2012

  2. Seente sarnasus taimedega Seente sarnasus loomadega • Kasvavad ühel kohal ega liigu aktiivselt • Seenerakkudel on rakukestad - kitiinist • Kasvavad kogu elu • Toituvad valmis orgaanilistest ainetest, mida saavad väliskeskkonnast • Rakkudes talletuvad samasugused varuained Seente sarnasus …

  3. Kust seeni leida võib? • Kõige kiiremini kasvavad seened soojas, niiskes paigas, kus on rohkesti toitaineid.

  4. Seente ehitus • Hulkraksed seened koosnevad seeneniitidest • Harunenud ja omavahel põimunud seeneniitide võrgustik moodustab seeneniidistiku ehk MÜTSEELI

  5. Viljakehad • Viljakehad koosnevad tihedasti põimunud seeneniitidest • Neis valmivad paljunemiseks ja levimiseks eosed

  6. Seente paljunemine ja levik • Seened levivad eostega • Mitmed seeneliigid vajavad eoste idanemiseks eritingimusi.

  7. Miks on seenele vaja seeneniite? Seeneniidistik eritab ümbritsevasse keskkonda aineid, mis lõhustavad toidu lihtsateks molekulideks Need molekulid lahustuvad vees ning imenduvad seenerakkudesse. Erinevalt loomadest lõhustavad seened toidu väljaspool keha

  8. Seente mitmekesisus

  9. Pärmseened on erinevalt teistest seentest üherakulised ning neil pole niidistikku. Pärmseened saavad suhkrut lagundades eluks vajalikku energiat. Suhkrute lagunemist hapnikuvabas keskkonnas nimetatakse KÄÄRIMISEKS Paljunevad eostega ja pungudes.

  10. Pärmseente kasutamine
