Photosynthesis Quiz

Photosynthesis: Definition, Significance, and Process

• Photosynthesis is the process by which plants absorb light energy and convert it into chemical energy.
• During photosynthesis, water, carbon dioxide, and other minerals are transformed into oxygen and organic compounds.
• Photosynthesis allows plants to store light energy as chemical energy, which is used by animals and humans when they consume plants.
• Photosynthesis also enables plants and other organisms to form the base of the food chain.
• Plants consume carbon dioxide and release oxygen during photosynthesis, which is essential for human survival.
• The first step of photosynthesis is the absorption of light by chlorophylls, which are connected with proteins in the thylakoids sack of chloroplasts.
• After absorbing light, electrons are eliminated from water and pass to a major electron acceptor known as Quinine.
• Electrons are then transferred to the final electron acceptor, an NADP positive, by the chain of electron transfer.
• ATP is produced during this process, which is the most important source of energy in a plant's biological process.
• Carbon fixation occurs when NADP and ATP produce energy by reducing carbon into six-carbon molecules.
• The process of reducing carbon is known as the Calvin Cycle, which is light-independent and called dark reactions.
• Light reactions occur within the thylakoid of the chloroplast and use two photosystems, photosystem 1 and photosystem 2, to produce ATP and NADPH.
