Question biology homework

We are instructed to answer these questions about Paramecium, but we didn't get to view them. Can anybody help?
1) How does movement of Paramecium compare to that of Amoeba?
2) How does shape and body consistency differ between Amoeba and Paramecuim?
3) What structures in Amoeba and Paramecuim also occur in plant cells?
4) What structures in Amoeba and Paramecuim do not occur in plant cells?

For the first two, I'd do a search on YouTube for videos of the two organisms you're asked about.

For the last two, I hope your textbook has some diagrams of these cells. If not, try Google.

1. Paramecium uses cilia while the amoeba uses pseudopod.
2. Paramecium have a stiff pellicle coating that gives it a constant spheroid shape, while the amoeba is very flexible and constantly changes shape.
3. Hmmm, nucleus, cell membrane, vacuoules,...
4. Definitely locomotive organelles pseudopodia, cilia,...

Damn High School Biology is tough
