Photosynthesis Quiz

The main purpose of photosynthesis in plants is to produce organic compounds, especially sugars, using light energy.

The two sets of reactions involved in photosynthesis are the light-dependent reactions and the Calvin Cycle.

The structures inside plant cells responsible for photosynthesis are special organelles called chloroplasts.

<p>Thylakoids are disks inside chloroplasts with pigments that absorb light energy. They act like solar panels in the chloroplast, absorbing light energy from the sun.</p> Signup and view all the answers

<p>The pigments such as chlorophyll are found in the thylakoid membrane, where light is absorbed. They are arranged in clusters called photosystems.</p> Signup and view all the answers

<p>Electrons in chlorophyll gain energy and leave chlorophyll to move to the electron transport chain. Water is split to replace the lost electrons, producing electrons, hydrogen ions, and oxygen.</p> Signup and view all the answers

<p>The electron transport chain transports electrons and uses their energy to pump hydrogen ions across the thylakoid membrane, creating a high concentration of hydrogen ions inside the thylakoid.</p> Signup and view all the answers

<p>ATP is produced as hydrogen ions passively diffuse through ATP synthase from high to low concentration, causing ATP synthase to spin and produce ATP.</p> Signup and view all the answers
