Kingdom Protista (Protozoa) Chapter 25 Protists are a diverse group of eukaryotic organisms, most of which are microscopic. Mostly unicellular eukaryotic organisms that live in aquatic environments. Describe the protists various body plans), methods of motility, nutrition type and mode of reproduction Kingdom Protista: Zooflagellates: Are these organisms mostly unicellular heterotrophs, or autotrophic? How do they move? Are they monophyletic – if not why? Diplomonads: (Fig 25-5) What is so interesting about the nuclear content of these organisms? Unlike most animals they do not have certain organelles; which are missing and why ? Give two examples of parasitic species within this group Euglenoids: (fig 25-6) are zooflagellates with disclike cristae in mitochondria. Describe the life cycle of Trypanosoma, which causes African sleeping sickness? Is this organism found in the blood, tissues, interstitial fluids; how is it transmitted? Ciliates: (Fig 25-7) Move by hairlike cilia (9 x 2 microtubule arrangement) - short and numerous Why do they contain micronuclei and macronuclei, and what type of reproductive cycle dominates – is it sexual or nonsexual ? Apicomplexans (Fig 25-10) Are these organisms parasites or free living ? What is their resting stage called? Are they nonmotile, or motile ? The apical complex of microtubules attaches the apicomplexan to its host. How does it penentrate its host ? Describe the life cycle of Plasmodium transmitted by the Anopheles mosquito…. . Foraminiferans and actinopods (Fig 25-20,21) Amoeboid cells that often have hard outer shells (tests) through which cytoplasmic projections extend. How do these organisms obtain food and move ? What happens to their shells when they die ? What’s unique about the actinopods ? Amoebas (Fig 25-22): Use cytoplasmic extensions (pseudopodia) to move and obtain food by phagocytosis e.g. Entamoeba histolytica. What disease does this organism cause, and how does it infect its host. Describe its life cycle. *********************************************************************** The Animal Kingdom: Animalia An Introduction to Animal Diversity Chapter 29

What characteristics are common to most animals? Do they have specialized organs for specific functions? Are they heterotrophic, autotrophic? Are the gas exchange and waste disposal systems the same for small and large animals? Structure: Animals have diverse body plans with a basic structure and functional design adapted to obtaining food and reproduction. How is body plan important to life challenges Function: Most animals are capable of locomotion at some time during life cycle e.g. sponges and corals have immature larvae that move; sessile as adults. Can reproduction be carried out asexually? Describe sexual reproduction in the sponges
