chapter 26 biology protists

pseudopodia are used by amoeba for ingesting food as well as for:

locomotion

which eukaryotic organelles likely arose from symbiotic relationships between larger cells and bacteria?

mitochondria and chloroplasts

which protist group typically consists of amoeboid cells surrounded by a hard outer shell through which cytoplasmic projections extend?
