1. excellent, I have been using this method for years, it is great to have a demo that all the class can easily see before they have a go, many many thanks
    By the way; stoma is the singular and stomata is the plural

  2. Thanks a lot for the awesomely educational videos!! I have a question about Stomata and heat. Does heat cause Stomata to open or to close? I heard that if you want to supplement CO2 to your plants you need higher temperatures. I just can't wrap my head around it. Wouldn't a plant want to conserve water and close stomata in hotter environment?

  3. I have watched a couple of your videos snd it's helpful since science is not my best subject.. or my favorite ha ha 🙂
