Free Photosynthesis Diagram Generator

A photosynthesis diagram shows how plants convert sunlight, water, and carbon dioxide into glucose and oxygen. It maps the light-dependent reactions in the thylakoid membranes and the Calvin cycle in the stroma, with labeled arrows tracing electrons, ATP, NADPH, and carbon fixation. SciFig's photosynthesis diagram generator can label every stage or leave the figure blank for practice.

The two stages are the light-dependent reactions and the light-independent Calvin cycle. The light-dependent reactions occur in the thylakoid membrane and split water to make ATP and NADPH; the Calvin cycle then uses those products in the stroma to fix carbon dioxide into glucose. A labeled photosynthesis diagram places each stage in its correct chloroplast compartment.

The light reactions occur in the thylakoid membranes of the chloroplast, and the dark reactions (the Calvin cycle) occur in the surrounding stroma. A clear photosynthesis process diagram shows this spatial separation, which is essential for understanding how captured light energy is later used to build sugar.

Describe the stages and labels you want and SciFig generates the figure for you. A fully labeled photosynthesis diagram includes the chloroplast, thylakoid, stroma, sunlight input, water and carbon dioxide inputs, and oxygen and glucose outputs. SciFig's photosynthesis diagram generator produces labeled or blank versions from the same scientifically accurate base.

Chlorophyll is the green pigment in the thylakoid membranes that absorbs light energy to drive the light-dependent reactions. A chlorophyll diagram highlights the pigment molecules and photosystems where light is captured. SciFig can show pigments within the full figure or focus a chlorophyll diagram on the photosystems alone.

Photosynthesis and cellular respiration are complementary processes. Photosynthesis stores energy in glucose using carbon dioxide and water, while cellular respiration releases that energy and returns carbon dioxide and water. Diagrams often pair the two to show how carbon and oxygen move between plants and the atmosphere.
