Plant leaf lamina is the flat region of the leaf containing the chloroplasts, veins and the stomata. On the other hand, the leaf blade, in botanical terms, is the entire flat and thin part that is connected to the stem (petiole)

The Function of Lamina Include

⦿ The lamina absorbs sunlight for photosynthesis, which is the process of converting carbon dioxide, water, and UV light into glucose.

⦿ The lamina controls the number of stomata and the photosynthetic reaction centers thereby controlling the exchange of carbon dioxide and oxygen.
