nature often keeps me busy concentrating to not just stare at something with an open mouth.
in a recent class, we looked at developmental stages of plant embryos, from the zygote to a fully grown embryo inside a mature seed.
the animation below shows a young embryo that is being formed inside the ovule (entire structure). it will grow from a single cell to a complete, viable plant embryo, and the surrounding space will be filled with nutrients and storage substances that will give the little germinating seed the best chances possible.
