1

Protista

Asexual Reproduction, Methods of movement used to differentiate groups. All single celled eukaryotes.

2

Choanoflagellate

Single Celled Eukaryotic Ancestor to the Animals.

3

Protozoa

First Animals. Motile, heterotrophic. Animacules. Subcellular specialization rather than cellular specialization like in metazoa.

4

Euglenozoa

W/in Protozoa. Autotrophic and Heterotrophic. Some can switch from auto to heterotroph.

5

Euglenoidea

Autotrophs and Heterotrophs, can switch. Chloroplasts and pyrenoids. Pellicle. 2 Flagella. Clonal Reproduction. W/in Protozoa.

6

Kinetoplastida

Heterotrophic, mostly parasites. Kinetoplast - large mass of DNA in single mitochondrium. Undulating membrane. Chagas and sleeping sickness. W/in Protozoa.

7

Chlorophyta

W/in Protozoa. Green algae. Close relatives to plants. Volvocida - simple example of multicellularity, all flagellated. Solitary and colonial. Clonal or sexual reproduction. Gonidia.

8

Retortamonada and Axostylata

W/in Protozoa. Retortamonada - Giardia. Axostylata - Axostyle, STD.

9

Alveolata

W/in Protozoa. Unique alveoli: cortical vesicles that support the cell membrane.

10

Dinoflagellata

W/in Protozoa. W/in Alveolata. Usually 2 flagella. Sulcus - longitudinal groove with one flagellum. Cingulum - transverse grooove that also has a flagellum. Theca - rigid cellulose, often sculpted skeleton, occurs in alvioli. Auto and heterotrophic.

11

Ciliophora

W/in Protozoa. W/in Alveolata. Heterotrophic. Multi cilia. Alveolar vesicles. Mitochondria w/ tubular cristae. 2 Types of nuclei. Carbs stored as glycogen.

12

Apicomplexa

W/in Protozoa. Important parasites. Malaria and Coccidiosis. Apical complex, gliding locomotion, no cilia. Plasmodium and Toxoplasma.

13

Ameboid protozoa

Amebas, Foraminifera, Actinopoda. W/in Protozoa. Transition of cytoplasm to stiff ectoplasm. Pseudopodia - lobopodia and filopodia. Test - protein or siliceous.

14

Foraminifera

Extinct. W/in Protozoa. Ameboid protozoa. Mostly marine, reticulopodia - like a network of podia. Extracelluar test, diverse fossil fauna.

15

Rhizaria

W/in Protozoa. Cercozoa, Foraminifera, Radiolaris.

16

Actinopoda

W/in Protozoa. Radiolaria and Heliozoa. Axopodia: needle like pseudopodia, for prey capture, flotation, locomotion, attachment. Sometimes inorganic test.

17

Radiolaria

W/in Protozoa. W/in Actinopoda. Have organic and siliceous test. Mostly planktonic, algal symbionts.

18

Heliozoa

W/in Protozoa. W/in Actinopoda. Mostly benthic, some planktonic. Siliceous spicules (spikes), algal symbionts.
