What characteristics define the Kingdom Protista?

single celled organisms

heterotrophic

Which groups are included in the Protozoa?

ameobas, actinopods, foraminiferans, apicomplexans, ciliates, flagellates

For each group, what is its major means of locomotion?

ameobas - pseudopodia, actinopods - axopods, foraminiferans - cytoplasmic extensions, apicomplexans - flexing/bending, ciliates - cilia, flagellates - flagella

ameobas

pseudopodia, lobose, food vacuole

actinopods

pores, axopods, radiolarian

foraminiferans

tests, cytoplasmic extensions, pored

flagellates

null

ciliates

pellicle, cilia, macro/micronucleous

apicomplexans

bend/flex, parasitic, apical complex

How do heterotrophs obtain food?

by ingesting another organisms

Do excavates have mitochondria?

What disease does Giardia intestinalis cause?

backpackers diarrhea

What is the shape of the mitochondrial cristae in Trypanosoma brucei?

disk shaped

In choanoflagellates, a collar of ____________ surrounds the __________.

microvilli, flagellum

From what structures is the pellicle of ciliates formed?

alveoli

Describe the function of the two nuclei in ciliates.

micro nuclei - sexual reproduction

macro nuclei - metabolism and growth

Is conjugation sexual or asexual reproduction and why?

sexual

it is an exchange of micronulei between opposite mating types

What is the function of the apical complex?

allows apicomplexans to attach and penetrate into host cells

The White Cliffs of Dover are comprised of the shells of what organisms?

foraminiferans

Axopods are characteristic of which protists?

actinopods

What structure do amoebae use for feeding?

pseudopodia to engulf food

food vacuole and lysosome to digest

Describe 7 characteristics which define the Kingdom Animalia

multicellular, differentiated tissues, specialized organs, heterotrophs, lack cell walls, locomotion, sense organs and nervous system, sexual reproduction

Within the Kingdom Animalia, what characteristic separates the Parazoa and Eumetazoa

parazoa lack clearly defined tissues and organs

Which phylum is included in the Parazoa

phylum porifera (sponges)

How do sponges get their food?

water travels through pores to the spongocoel. particles are trapped by choanocytes and digestion occurs wtihin choanocytes (intracellular digestion)

The Subkingdom Eumetazoa is divided into two “branches” on the basis of symmetry. What are they?

radial symmetry - circular or wheel formed body

bilateral symmetry - body can be divided by only 1 plane that goes through midline. right and left halves

What other characteristic distinguishes these two groups of eumetazoa

embryonic tissue development

diploblastic - ectoderm and endoderm (branch radiata)

triploblastic - endoderm, ectoderm, mesoderm (branch bilateria)
