Phyla of Protists *Move using pseudopodia *Have double shells made of silica *Photosynthetic protists; can be multicellular *Move using flagella *Move using cilia *Fungus like protists *Form resistant spores An interesting group of protists consists of amoebas and forams. These protists are distinguished by their unique form of locomotion, in which they use extensions of cytoplasm. Amoebas and forams are unicellular heterotrophs. Amoebas, members of the phylum Rhizopoda, are protists that live in fresh and …showed first 75 words of 1120 total…

Gametes fuse to form a zygote, which develops in the wall of the mosquito's gut and produces large numbers of sporozoites.
