Hank explains the extremely complex series of reactions whereby plants feed themselves on sunlight, carbon dioxide and water, and also create some by products we're pretty fond of as well.

From www.biolog.ie. Vodcasts and revision courses for Leaving Cert Biology students. Final vodcast in the photosynthesis series. This shows how glucose is produced by the plant from ATP, NADPH and CO2.
From www.biolog.ie. Vodcasts and revision courses for Leaving Cert Biology students.Green plants have the special ability to trap energy from the sun, combine it with other molecules and make food. The sun therefore is the ultimate source of energy for life on earth!
This vodcast explains what photosynthesis is all about and what the plant needs to make it happen.........
