22. C-3 photosynthesis works well as long as stomates remain open.

23. Photorespiration when stomates Close produces a 2-C compound that cannot be used to make sugar. C-4 photosynthesis keeps carbon dioxide concentration high so photorespiration does not occur.

29. Animals have six major adaptations to anoxia.
