Guard Cells

Specialized cells that surround the stomata in plant leaves and control their opening and closing for gas exchange.

Transpiration

The process by which water is absorbed by plant roots, moves through plants, and evaporates from aerial parts, like leaves, stems, and flowers.

Stomata

Microscopic openings on the surfaces of leaves and stems that regulate gas exchange, including water vapor release and carbon dioxide uptake for photosynthesis.

Modified Leaves

Leaves that have evolved to perform functions other than photosynthesis, such as protection, storage, or reproduction.
