6H2O + 6CO2 + Light Energy -> C6H12O6 + 6O2

Definition: Process in which plants use the sun's energy to make high-energy sugars.

Light Dependent: First stage of photosynthesis. A process by which plants capture and store energy from sunlight. ADP, NADP+, H20 and light go into the light dependent reactions.

Light Independent: Chemical reactions that convert carbon dioxide and other compounds into glucose. Occurs in the stroma. ATP and NADPH are produced by light independent reactions.

This is how plants produce energy. They are autotrophs, meaning they make their own food. They take in sunlight and convert it to energy in the form of ATP. Without it, plants would die, therefore it's required for life.


The chloroplast is a large, complex double membrane organelle that performs the function of photosynthesis within plant cells and contains the substance chlorophyll which is essential for this process.

* Inner Membrane - Located under the smooth outer membrane.

* Outer Membrane - The smooth outer covering of the chloroplast.

* Thylakoid - A flattened membrane sac inside the chloroplast, used to convert light energy into chemical energy.

* Granum - A stack of thylakoids in a chloroplast.

* Stroma - The fluid of the chloroplast surrounding the thylakoid membrane.

* Lamellae - The tissue that connects the grana to each other.

* Chorlophyll - Green pigment in plants that absorbs light energy used to carry out photosynthesis.
