New cards

What side is the clitellum on, on an earthworm?

Dorsal side

New cards

Did the earthworms move faster on paper or plastic? Why?

Faster on paper, had more friction for the worms to grab onto to move forward.

40
New cards

Why would a plant feeding nematode have a stylet rather than a species that feeds on microbes or animal tissue?

To mechanically pierce through the plant cell walls and inject digestive enzymes to suck out the host cytoplasm
