\" \" Mesodinium chamaeleon is an unusual organism of the genus Mesodinium which symbiotically combines aspects of both animal and plant biology. But a single-celled organism called Mesodinium chamaeleon blurs the line between animal and vegetable. Normally, enzymes enter food vacuoles and digest what's inside, which is how the organism gets energy. But instead of being digested, algae lives inside M. chamaeleon vacuoles like tiny solar panels turning sunlight into energy, which M. chamaeleon then consumes. How does M. chamaeleon keep the algae alive even though it's an animal and they're plants?
