Hiro is very pleased to find that Subzero is a fellow scientist and a bit of a snarker -- just like him! Only about 100 times as big and probably also able to fly. "The photosynthesis stuff is pretty basic stuff, but I took a couple AP bio classes in high school." Watch him leave it up to Sam to explain that Hiro isn't the typical age to know quite this much about stuff.

And then, prompted by Sam saying big words -- "That's the true grass, poaceae, makes up 20% of Earth's ground cover. Dandelions are family plantae, order asterales, family asteraceae, genus taraxacum, tap-rooted, perennial, herbaceous plants, native to temperate areas of the Northern Hemisphere."

....okay now he's just showing off.
