High School Level - Botany: Photosynthesis Works Differently in Beans than it does in Corn
Detailed Explanation of C3 (ex. wheat, rice, beans and 95% of other plant species) vs. C4 Plants (ex. corn)
Photosynthesis occurs in Mesophyll Cells for bean plants that use a three carbon molecule (C3) to capture carbon dioxide.
Photosynthesis occurs in Bundle Sheath Cells for corn plants that first use a four carbon molecule (C4) in the mesophyll to capture carbon dioxide. C4 plants work more efficiently on hot summer days.

College Level - Biochemistry: The "C4" molecule in C4 Plants is called Oxaloacetate
The four carbon molecule in C4 Plants is called "oxaloacetate".  The oxaloacetate helps corn operate differently at the molecular level, impacting nitrogen uptake and plant growth rates.  Understanding C4 metabolism helps us increase crop yields, decrease nutrient runoff, and generate new knowledge that may lead to future scientific breakthroughs.
