Definitions:

Carbon Fixation

Carbon fixation is the process by which inorganic carbon (typically carbon dioxide) is converted into organic compounds by living organisms, notably in photosynthesis.

Mesophyll Cells

Photosynthetic cells located in the interior of leaves, between the upper and lower epidermis, responsible for the production of plant's food through photosynthesis.

Bundle Sheath Cells

Specialized cells in plant leaves surrounding the vascular bundles, notably in C4 plants, playing a critical role in photosynthesis and carbon fixation.

C4 Pathway

The C4 pathway is a photosynthetic process in some plants that captures carbon dioxide more efficiently in hot, dry climates, enhancing their ability to fix carbon.
