25
Phylum parabasalida
Symbiotic (mutualistic or paralistic) inside multicellular organisms like plants and animals
26
Trichonympha
Lives inside intestines of termites, breaks down cellulose for termites
27
Trichomonas vaginalis
“phylum Parabasalida. It is sexually transmitted and causes a nasty disease
28
Phylum Kinetoplastida
Some are free living some are mutualistic or parasites
29
Phylum Actinopoda
“amoeboid cells with numerous axopodia; some with glassy (silica) skeletons
30
axopodia
“supported by microtubules. Axopodia serve as food-gathering devices, collecting small organisms and transporting them internally back to the main cell body”
31
Phylum Foraminifera
“amoebas with porous, calcium carbonate shells; pseudopodia long, branching and sometimes flowing together
32
Phylum Apicomplexa
These are parasites. Their life cycles often involve several stages in two hosts, one a vertebrate, and the other an invertebrate. They possess an apical complex of specialized structures used to penetrate host cells.
33
Plasmodium
Plasmodium causes malaria, a frequent and life-threatening disease of humans and other vertebrates. Mosquitoes transmit the parasite from one vertebrate host to another.
34
Phylum Ciliata
This is the largest of the Alveolata phyla. All members of the Ciliata have numerous cilia used for locomotion, feeding, or both. All are heterotrophic and many are quite specialized in body form.
35
Macronucleus | Micronuclei
Controls cell activity | Exchanged during sexual reproduction
36
Cytosome
In paramecium | Oral groove
37
Contractile vacuoles
Pulsating near the end of cell
38
Phylum Oomycota
The Oomycota, or “water molds”, resemble fungi in appearance and feeding mode, but they could hardly be farther on the phylogeny of fungi
39
oogonia
obvious dark structures that are much larger than a hypha is wide are
40
Psuedopodia
Feed or creep around surfaces using lobe like extensions
41

Psuedopodia Single nucleus Reproduction No spores
