Photosynthesis

Energy cannot be created or destroyed, it can only be transformed

All organisms need carbohydrates for energy conversion

What organelle is produces cellular energy?

Glucose C6H12O6 is a carbohydrate

Autotrophs are capable of making their own carbohydrates

Heterotrophs are not capable of making their own carbohydrates and therefore must get them by some other means

Why do we have to eat to get energy?

What form is cellular energy in?

Carbohydrates are made in the chloroplast in a process called photosynthesis

Plants and other photosynthetic organism are green because they contain the pigment chlorophyll

Light from the sun contains all the colors of the spectrum (rainbow).

Chlorophyll absorbs all the colors except for green.

The wavelength of light that is green is reflected. That is why we see plants as green

What carbohydrate do plants make?

Glucose

We get energy from the sun. This energy is in the form of

Radiant Energy

Photosynthesis: Plants use the energy from sunlight to convert water (H2O) and carbon dioxide (CO2) into high-energy carbohydrates

Photosynthesis Equation: 6CO2 + 6 H2O -> C6H12O6 + 6

O2

Sunlight

Reactants (what goes in) Carbon dioxide Water

Products (when the reaction is done) Glucose Oxygen
