This really involves symbiotic algae, rather than true plants, but maybe
it will still teach the concepts you want:
Have the students raise mixtures of Chlorhydra and nongreen hydra, or
green and non-green paramecium with 4 treatments: with and without light
and with and without food. The dark will kill the endosymbiotic
chlorella species or drive it into colorless dormancy, while green
individuals individuals will dominate in the + light, - food treatment.
Let me know how it works for you if you try it.
