This worksheet describes the structures of the unicellular protist known as the ameba. Though NGSS standards do not require units on protozoans, this can still be a useful exercise for examining how structure relates to function and how single-celled organisms move, consume food, and reproduce.
Students read a passage that describes cell parts such as the nucleus, contractile vacuole, endoplasm, and pseudopodia and then color these structures on a drawing of the ameba. Worksheet questions can be answered by reading the passage carefully.
