Stomata are crucial microscopic pores on plant leaves and stems that act as tiny mouths, regulating gas exchange (taking in CO2 for photosynthesis, releasing O2/water vapor) and balancing water loss, controlled by specialized guard cells that open and close the pore.

    Where are you seeing them, because I do not

    Are the stomatas in the room with us??

    Reminds me of a road map of some suburban area. You have a few major highways that lead off into main thoroughfares that branch off into neighborhood roads. I’m picturing each little space filled with cookie cutter houses that all look the same.

    What plant is the leaf from, and is this magnified at all?

    There are plenty of plants with epidermal leaf cells visible to the naked eye. It’s possible you’re seeing the stomata with minimal magnification.

    For example, Tradescantia fluminensis has epidermal cells often over 100 microns, and humans can see something as small as 40 microns. With just a little magnification you can see their stomata. This clearly is not a trad though!

    Eta: I’m also assuming some resolution was lost on the pic when posted if it’s slightly magnified

    If you’re talking about the brown spots? Those ain’t stomata.

    Did you lose res on the Pic so we can’t see them or summat?

    Your description is great and the picture is very good.

    I am trying to figure out if I can see them or not.

    Between the ‘square’ shaped vein structures I can see a cross pattern going into a central bright spot, would this be what I am looking for!?!

    I am learning about this stuff so this is very cool to me.
