Photosynthesis

The process by which green plants use sunlight to synthesize foods with the help of carbon dioxide and water, producing glucose and oxygen.

Chloroplast

An organelle found in plant cells that is the site of photosynthesis.

Stroma

The fluid-filled space surrounding the thylakoids in a chloroplast, important for the light-independent reactions.

Thylakoid

A membrane-bound compartment inside chloroplasts where the light-dependent reactions of photosynthesis take place.

Granum

A stack of thylakoids within the chloroplast.

Gas Exchange

The process by which plants take in carbon dioxide and release oxygen through tiny pores known as stoma.

Redox Reaction

A chemical reaction involving the transfer of electrons, present in both photosynthesis and cellular respiration.

Chlorophyll

A green pigment found in chloroplasts that captures light energy for photosynthesis.

LEO goes GER

Mnemonic for remembering the concept of oxidation and reduction: Lose Electrons Oxidized, Gain Electrons Reduced.

Cellular Respiration

The process by which cells convert glucose and oxygen into energy, producing carbon dioxide and water as byproducts.

Energy Flow

The one-way transfer of energy through an ecosystem, typically initiated by sunlight and converted to chemical energy in photosynthesis.

Photosynthesis Equation

The chemical equation summarizing photosynthesis: CO2 + H2O + light energy → C6H12O6 (glucose) + O2.
