What do you know about photosynthesis?

Answer the true/false questions using your prior knowledge about photosynthesis.

____ 1. Photosynthesisis important because it uses excess oxygen in the atmosphere.

____ 2. Photosynthesis creates energy.

____ 3. Photosynthesis stores energy in the bonds of glucose.

____ 4. Water is a necessary ingredient for photosynthesis.

____ 5. Carbon dioxide is produced by photosynthesis.

____ 6. The gasoline used to drive to school today is ultimately the result of photosynthesis.

____ 7. Chlorophyll, contained in the mitochondria, traps light energy for photosynthesis.

Photosynthesis…the process through which plants

convert light energy to chemical energy in order to produce food

The energy involved in photosynthesis is stored in the chemical bonds of carbohydrates.

Photosynthesis Equation

H2O + CO2 C6H1206 + O2(water) + (carbon dioxide) (glucose) + (oxygen)

A balanced equation…

6H2O + 6CO2C6H12O6 + 6O2

ChloroplastLocated inside leaf cellsCapsule-shaped organelleContained by two membranes

Chloroplast PartsThylakoids: disk-shaped vesicles

stacked inside the chloroplastGranum: a stack of thylakoidsStroma: liquid material inside the

chloroplastChlorophyll: pigment located inside the

thylakoid; gives plants their green color

Photosynthesis

2 parts of photosynthesis – light dependent and light independent

Light dependent uses sunlight to make ATP

Light independent uses that ATP to make Glucose (CALVIN CYCLE)
