It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) generation of ATP, and (4) conversion of CO2 into carbohydrates (carbon fixation).

Summary. Photosynthesis occurs in the chloroplast, an organelle specific to plant cells. The light reactions of photosynthesis occur in the thylakoid membranes of the chloroplast. Electron carrier molecules are arranged in electron transport chains that produce ATP and NADPH, which temporarily store chemical energy.

Answer the follow Demonstrate that oxygen is released during photosynthesis. Material required: Beaker, water, test tube, funnel, Hydrilla plant.

Joseph Priestley (1733-1804) — Unitarian minister, teacher, author, and natural philosopher — was the Earl of Shelburne’s librarian and tutor to his sons. In this room, then a working laboratory, Priestley pursued his investigations of gases. On 1 August 1774 he discovered oxygen.

1) Yes, if you illuminate a plant (I presume you are using an aquatic/water plant) it will produce oxygen. You can put the plant under a funnel and collect the bubbles in an upturned test tube. If the gas is collected fresh, it will relight a glowing splint.

Plants make their food in a process called photosynthesis. Once they have water and carbon dioxide, they can use energy from sunlight to make their food. The leftovers from making the plant food is another gas called oxygen. This oxygen is released from the leaves into the air.
