Photosynthesis

ALL CELLS NEED ENERGY! ENERGY

Living Things Use Energy How do you get energy? What about plants?

What is photosynthesis? Process by which plants use sunlight to make their own food Photo = “light” Synth= “to make” Photosynthesis = to make from light.

Plant Cell Structure It all starts w/ a leaf…. which have chloroplasts… filled with chlorophyll. made of plant cells….

Plant Cell Structure chloroplasts Plant organelle in which photosynthesis occurs. Chlorophyll Green pigment (what makes leaves green) Inside chloroplasts. Absorbs light energy from sunlight.

The chlorophyll absorbs the sunlight.

Photosynthesis CO2 O2 IN OUT IN OUT IN Carbon Dioxide (air) Oxygen Energy OUT IN C6H12O6 (Glucose) (Sugar) H2O (Water)

EQUATION FOR PHOTOSYNTHESIS CARBON DIOXIDE WATER GLUCOSE OXYGEN CO2 + H2O + C6H12O6 + O2 ENERGY Plant food. Used for growth or reproduction OR stored for later. Waste

Awesome Miss. Eades... I could care less. Tell me one reason why I should even care. What does this have to do with me?

Well, it applies to you if you want to keep…. Breathing….. Eating….. Living…..

Plants and animals need each other to survive.

ALL CELLS NEED ENERGY! ENERGY

Respiration Process by which animal cells release energy from food.

RESPIRATION CO2 O2 OUT IN IN OUT Carbon Dioxide (air) Oxygen H2O (Water) C6H12O6 (Glucose) (Sugar)

EQUATION FOR RESPIRATION C6H12O6 + O2 CO2 + H2O + ENERGY GLUCOSE OXYGEN CARBON DIOXIDE WATER In our food Energy released from food for our bodies to use. Toxic Waste

PHOTOSYNTHESIS RESPIRATION CO2 + O2 H2O + C6H12O6 + C6H12O6 + O2 H2O + ENERGY C6H12O6 + O2 H2O + CO2 + ENERGY RESPIRATION

In Summary…

In summary, Plants need the CO2 we release… We need the O2 plants release… Plants/Animals depend upon each other for survival. Plants use photosynthesis Animals use respiration
