One of the many beautiful lessons to learn from plant species is in their resilience.
Since they cannot simply run away, they have evolved over their 430 million years of life on Earth to deal with the situation where they stand. They produce their own food through photosynthesis and hence have learnt to use it optimally. They protect themselves with evolved mechanisms like noxious chemicals, spines, sticky saps etc. while doing their best to adapt and adjust to their surroundings.
Observing a small plant can itself be a nice teaching moment.
