You could at least write, what plants are that.
Anyway, on the first picture are opened stomata, but I don't recognize, what's on the second one, that's not familiar to me.

Cis or trans? That's what matters.

they are present on plants which live in conditions where the water amounts are sparse
they are not present on the surface and they are hence called sunken this helps them reduce water lossess as a humid atmosphere is maintained

well, they don´t seem much under the surface to me. But the surface seem to be cover with some cuticule or something similar.
