Photosynthesis
Plants need (3) ingredients for photosynthesis
carbon dioxide
water
sunlight
Photosynthesis happens in two stages
Light reaction
happens in the daytime
makes (2) molecules
store and move energy
ATP,NDAPH
Dark reaction
happen anytime
make sugar
repeat over and over
When little light
Photosynthesis happens in the leaves
plans contain chlorophyll
takes/collect energy from the sun
makes sugar
makes chlorophyll
no sunlight , no sugar , no chlorophyll , no green
makes plants green
It is a pigment
Chlorophyll is not the only pigment
Plants use water and carbon dioxide
Takes energy from the sun and turns it into fuel
The fuel is stored as molecules such as glucose
This is food for the plant to grow
without food , all pigments disappear except the one that makes brown.
Photosynthesis changes molecules
6CO2 + 6H2O + light energy = C6H12O6 + 6O2
Photosynthesis takes place in plants ,algae and some bacteria
