Definitions:

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.

Light-Independent Reactions

Also known as the Calvin cycle, these are chemical reactions in photosynthesis that convert carbon dioxide and other compounds into glucose, occurring without the direct need for light.
