Bacteria

Bacteria. Cyanobacteria. Single-celled protists. Plants-Mosses. Sphagnum or peat moss. Liverwort. Ferns. Horsetails. Gymnosperm. Angiosperm. C-3 photosynthesis works well as long as stomates remain open. C-4 photosynthesis keeps carbon dioxide concentration high so photorespiration

Photosynthesis

Photosynthesis. Photosynthesis: CO 2 + H 2 O + Energy ?CH 2 O + O 2 + H 2 O Photosynthesis is a balance between competing processes. CH 2 0 | HO-C-H | COOH. CH 2 0 | HO-C-H | COOH. Two molecules of 3-phosphoglyceric acid (3PG). C3

Photosynthetic Pathways

Photosynthetic Pathways. C3 Photosynthesis: Used by most plants and algae. CO 2 + ribulose bisphosphate (5 carbon sugar) = phosphoglyceric acid (3 carbon acid). This is called the C3 pathway because the product (phosphoglyceric acid) is a 3-carbon molecule.
