an organism that produces its own nutrients from inorganic substances or from the environment

an organelle found in plant and algae cells where photosynthesis occurs

a green pigment that is present in most plant cells, gives them their green color, and that reacts with sunlight, carbon dioxide, and water to form carbs

a class of pigments that are present in the thylakoid membrane of plants and that assists in photosynthesis

in chloroplasts and mitochondria, a process in which the movement of protons down their concentration gradient across a membrane is coupled to ATP synthesis

electron transport chain

a series of molecules, found in the inner membrane of mitochondria and chloroplasts, through which electrons pass in a process that causes protons to build up on one side of the membrane

a stack of thylakoids in a chloroplast

the initial reactions in photosynthesis, which are triggered by the absorption of light

the process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to produce carbohydrates and oxygen

a substance that gives another substance or mixture its color

in the thylakoid membranes in chloroplasts, a cluster of chlorophyll and other pigment molecules that harvest light energy for the light reactions of photosynthesis

primary electron acceptor

in chloroplasts, an acceptor of electrons lost from chlorophyll a; found in the thylakoid membrane

in plants, the solution that surrounds the thylakoid in chloroplasts

a membrane system found within chloroplasts hat contains the components for photosynthesis

an organism that obtains organic food molecules by eating other organisms or their byproducts
