Cell Energy Photosynthesis

What do you know about photosynthesis? Answer the true/false questions using your prior knowledge about photosynthesis.

____ 1. Photosynthesis is 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 H 2 O + CO 2  C 6 H O 2 (water) + (carbon dioxide)  (glucose) + (oxygen) A balanced equation… 6H 2 O + 6CO 2  C 6 H 12 O 6 + 6O 2

Chloroplast Located inside leaf cells Capsule-shaped organelle Contained by two membranes

Chloroplast Parts Thylakoids: disk-shaped vesicles stacked inside the chloroplast Granum: a stack of thylakoids Stroma: liquid material inside the chloroplast Chlorophyll: 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)
