Photo of a handful of roasted, shelled peanuts in the palm of a hand. Some are split into two halves (the cotyledons).
Not all seeds have endosperm as their storage tissue. Some seeds store the energy needed for germination in the embryo’s cotyledons. You know peanuts: the 2 halves are the 2 cotyledons. The embryonic root & shoot are the little structures at the base. #cotyledon #Fabaceae #Botany 🌾🧪🌱
Reading one of the first publications documenting circadian rhythms in humans and it’s essentially two professors torturing an assistant prof.

#InkTober2025 Day 8: Reckless.
Was planning to draw an eloborate scene from the time when birds ate horses. But it was one of those days and I’m glad I at least got this guy on paper, Terrorbird Titanis walleri. Based on Blue Rhino Studio’s amazing diorama, brushpen with Copic markers.
The taxodium were really looking great just downriver of Yankeetown this weekend, too!
