explain the word " 2000-Watt-Gesellschaft"
current world average rate of total energy
but big differences between the countries
describe two examples of organisms that live together and all profit from the partnership (symbiosis)
Example: Lichen
fungus --> water and minerals
algae --> carbonhydrate
describe two examples of organisms that live together and only one organism profit
Example1: Malaria Mücke bekommt Nahrung und kann Virus weiter verbreiten
Mensch/Tier bekommt Krankheit
Tell which properties of life have to do with which organelle
Membrane --> äussere Begrenzung, Stoffwechsel, Wasserhaushalt
Mitochondria --> Stoffwechsel, Atmung, Energieverbrauch
Chloroplast --> photosynthesis
Why are cells small?
Because they work many together in tissues which have their own work
?
Nucleus, enthält DNA, speichert und gibt Informationen weiter
?
Cell membrane --> äussere Hülle, Stoffwechsel, Abgrenzung
?
ribosom --> Eiweissherstellung
?
Speicherung & Abgabe v. Stoffen
?
Mitochondrium --> Energiegewinnung ( Kraftwerk der Zelle)
?
Endoplasmatisches Reticulum --> Produktion, Speicherung & Transport v. Stoffen
Plantcell?
Vakuole & Chloroplasten zusätzlich
reaction photosynthesis
endothermic reaction in the chloroplast of plants
carbondioida & water + light --> glucose & oxygen
1.dark reaction?
2. light reaction?
1. transforms carbon dioxide into glucose
2. splits water molecules into H+-Ions and oxygen
multi celluar organism
organism -> plant
organ -> leaf
tissue -> messophyll cells
cell --> mesophyll
organell --> chloroplast
importance of red and blue-violet light for photosynthesis
we see the leaf green because the pigments in the leaf absorb violet-blue and red light while transmitting and reflecting green light
reaction of cellular respiration
in the mitochondrion glucose and oxygen react to carbon dioxide and water
--> the energy in form of ATP
--> can use in different places in the body
cellular respiration & Gas exchange in lungs
cellular respiration --> gas exchange in tissue
gas exchange in lungs --> gas exchange between blood and air
