A very much summarised version of photosynthesis. Always use your text book as these videos in no way ever replace any textbook or teacher guidance. Not to be used in any commercial endeavour. An optional study resource for my students.
A summary of the leaf adaptations-for Irish Biology Exams Only! Not for monetary gain, not for commercial use and not to replace any textbook or teacher guidance. Made with icons from www.thenounproject.com. Made using the Adobe Spark Video App. Full credit to all sources always intended.
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.........
