Question

what is the specific function of stomata and cork cambium

Answer 1

Stomata helps in trapping sunlight nd helps in photosynthesis when its open
It helps in gaseous exchange also
Cork cambium is a tissue found in many vascular plants as part of the periderm. The cork cambium is a lateral meristem and is responsible for secondary growth that replaces the epidermis in roots and stems.

Answer 2

When stomata are open exchange of gases take place, this facilitates photosynthesis.
During photosynthesis CO2 is taken from atmosphere and KE is released.

the cork cambium forms in living cells of the epidermis, cortex, or, in some plants, phloem and produces a secondary protective tissue, the periderm. The cork cambium is, like the vascular cambium, a lateral meristem that produces cells internally and externally by tangential divisions.
