27
Q

Trichomonas vaginalis

A

“phylum Parabasalida. It is sexually transmitted and causes a nasty disease

28
Q

Phylum Kinetoplastida

A

Some are free living some are mutualistic or parasites

29
Q

Phylum Actinopoda

A

“amoeboid cells with numerous axopodia; some with glassy (silica) skeletons

30
Q

axopodia

A

“supported by microtubules. Axopodia serve as food-gathering devices, collecting small organisms and transporting them internally back to the main cell body”

31
Q

Phylum Foraminifera

A

“amoebas with porous, calcium carbonate shells; pseudopodia long, branching and sometimes flowing together

32
Q

Phylum Apicomplexa

A

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
Q

Plasmodium

A

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
Q

Phylum Ciliata

A

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
Q

Macronucleus

Micronuclei

A

Controls cell activity

Exchanged during sexual reproduction

36
Q

Cytosome

A

In paramecium

Oral groove

37
Q

Contractile vacuoles

A

Pulsating near the end of cell

38
Q

Phylum Oomycota

A

The Oomycota, or “water molds”, resemble fungi in appearance and feeding mode, but they could hardly be farther on the phylogeny of fungi

39
Q

oogonia

A

obvious dark structures that are much larger than a hypha is wide are

40
Q

Psuedopodia

A

Feed or creep around surfaces using lobe like extensions
