Planaria

We did an awesome lab with planaria! We got to see them with microscopes and with our bare eyes. Then we gave them egg yolk to eat and got to see them eat. The planaria senses the food with chemoreceptor cells.The planaria eats by wrapping its body around the prey, sliming it, and then sticking out its mouth tube and sucking on the prey. The planaria does not have eyeballs but eyespots that can only see light and dark. What do you know about planaria? (by Mika A)

  1. I wonder what would happen if humans only had eyespots not eyes? Everyone would be hiding in the shade and bumping into things.
