photo – synthesis

What is involved with photosynthesis?

Water (H2O)

Carbon Dioxide (CO2)

Lets Write the Reaction 2 Ways

Synthesis or Digestion?

Is energy stored or released?

What kind of reaction is photosynthesis?

Synthesis

Stored

The Chloroplast

What organelle does photosynthesis?

Chlorophyll is a pigment that absorbs light.

Chlorophyll

• Chlorophyll reflects green light.

Plants are Autotrophs. Autotrophs harness energy from an abiotic source.

What source of energy do Autotrophs tap into?

The SUN! Plants are Producers. Producers harness carbon from an abiotic source.

What source of carbon do Producers tap into?

Carbon Dioxide!
