The Protozoa Table 12.1
Protozoa – “first animal” • Eukaryotic • Unicellular • Chemoheterotrophs • Asexual reproduction is by fission or budding • Sexual reproduction by conjugation. Paramecium Figure 12.16
Archaezoa • No mitochondria • Multiple flagella • Giardia lamblia • Trichomonas vaginalis (no cyst stage) Figure 12.17b–d
Amoebozoa • Move by pseudopods • Naegleria fowleri Figure 12.18a
Apicomplexa • Nonmotile • Intracellular parasites • Complex life cycles • Plasmodium – causes Malaria
