Hey MinuteEarthlings! If you join us on Patreon this month at https://patreon.com/minuteearth, we will draw you a custom MinuteEarth stick figure (that we could feature in an upcoming video) AND send you a custom coffee mug with your beautiful stick figure on it!
Plants don’t make caffeine just for us, so what DO they make it for?
To learn more about this topic, start your googling with these keywords:
– Alkaloid: any of a class of nitrogenous organic compounds of plant origin which have pronounced physiological actions on humans.
– Allelopathy: the chemical inhibition of one plant (or other organism) by another, due to the release into the environment of substances acting as germination or growth inhibitors.
– Caffeine: a crystalline compound that is found especially in tea and coffee plants and is a stimulant of the central nervous system.
– Pesticide: a substance used for destroying insects or other organisms harmful to plants or to animals.
