What IS this?

Euglenas are one-celled,

eukaryotic organisms that live in

ponds. They have the following

characteristics:

• They are green and can make
  their own food.


• They have a whip-like structure
  called a flagella that they use to
  move around.


• They sometimes find food
  instead of making their own.
  Answer the following questions:

1. To which Kingdom do Euglenas
   belong?


2. Before the invention of the
   microscope, scientists
   classified all organisms as
   either animals or plants.
   Explain why they needed to
   invent a new Kingdom when
   they discovered Euglenas.
