Stomata in pine needle

Stomata in pine needles are small openings that facilitate gas exchange, allowing carbon dioxide to enter for photosynthesis while releasing oxygen and water vapor. Unlike broadleaf plants, pine needles have sunken stomata, which helps reduce water loss by minimizing exposure to air. This adaptation is crucial for survival in various environments, especially in colder or drier climates. Additionally, the needle's waxy cuticle further aids in conserving moisture.
