Which of these organisms have cell walls? Which have chloroplasts? Describe their organization.

Paramecium
Amoeba
Chilomonas
Volvox
Paranema

I've tried searching on the web, but the pages don't mention chloroplasts or cell walls. Which means they either don't have those things, or the pages just don't happen to mention them, and it seems weird that the assignment would ask me about organisms that have none of these features.

Thanks
