That process, called carbon fixation, resulted in the assembly of two three-carbon molecules called 3-phosphoglycerate (3-PGA ...
While 95% of plants use C3 photosynthesis, SciTechDaily explained, a new group of plants evolved to use C4 photosynthesis around 30 million years ago. C3 gets the job done, but it has flaws.
Cross sections of C3 rice (left) and C4 sorghum (right) shoots. Both grain crops evolved from a common ancestor, but sorghum evolved to photosynthesize more efficiently.
2. Carbon dioxide gas exchange - Role of light in photosynthetic CO2 fixation and respiration in C3 and C4 plants (2 weeks). 3. Nitrate reductase activity in plants - Effects of nitrate availability ...
