Yes they (some) can.
For example, Landsat "sees" (not sure about how much it can see in the dark! Thermal IR should work):
Blue-Green
Green
Red
Near IR
Mid-IR
Thermal IR
and another MID-IR band
Chlorophyll l appears red in the commonly produced false color images, because green plants reflects a lot of infrared light.
