The amazing….

Plants & other chlorophyll bearing organisms cyanobacteria are the most amazing living things. They can capture solar energy and transform it into energy-rich compounds that can be used by living organisms. The process is called photosynthesis.

The Basic Requirements of Photosynthesis and Its General Reactions Chlorophyll Carbon dioxide + water Solar energy chlorophyll sugar oxygen trap solar energy

The leaves of a plant are the primary organs of photosynthesis.

Inside a leaf cell, there are green structures called chloroplasts. Hydrilla leaf cells Photosynthetic activity takes place inside the chloroplasts. A series of reactions occur in which solar energy is converted into chemical energy.

Parts of a Chloroplast outer membrane inner membrane stroma thylakoid granum

There are two major events that occur during photosynthesis Light reaction which occurs at the thylakoid membranes in the presence of sunlight. Dark reaction occurs at the stroma (semi-fluid matrix within the chloroplsts.)

The light reaction Sunlight is absorbed in the thylakoid membranes. e-e- High-energy electron are produced. ADP NADP + Some e+ are passed to NADPH + converting to NADPH. ATP NADPH Dark reaction CO 2 H2OH2O glucose NADP + ADP
