1

don't memorize - just to put into context

2

trophozoite = 

cyst = 

encystation = 

excystation = 

motile feeding form

resting form

becomes cyst

leaves cyst

3

(Vesicular nucleus)

some have endosome and some don't

this is an important distinguishing feature

4

(Structure)

costa = 

axostyle =

filamentous rod like structure

clear rod like structure

5

(Locomotory organelles)

(pseudopodia)

temporary locomotory organelle, powered by sol/gel transformations

6

(Locomotory Organelles - Flagella)

1. central axoneme and basal sheath

2. tubule configuration?

3. anchored by what?

4. what has?

2. 9 + 2 microtubule configuration

3. basal body

4. mastigophora, some apicomplexa, some sarcodina

7

(Locomotory organelles)

(undulating membrane)

1-2. what have this?

(cilia)

small flagellae but more numerous

1. mastigophora (finlike organelle associated with flagella)

2. ciliates (fused cilia associated with gullet)

8

(Repro - asexual)

(binary fission)

1. longitudinal - what?

2. transverse - what?

3. nucleus or cytoplasm first?

4. vesicular nuclei and micronuclei divide how?

5. macronuclei divide how?

1. flagellates

2. ciliates

3. nucleus

4. mitotically

5. amitotically

9

(Repro - asexual)

(multiple fission - schizogony or merogony (same thing))

1. repeated nuclear division before what?

2. what does?

Q image thumb

1. cytokinesis

2. amoebas, some apicomplexa

10

(repro sexual forms)

1. what is fusion of male and female gametes to form a zygote called?

2. What is it called when two ciliates join and exchange nuclear material

only what unite?

 

1. syngamy

2. conjugation

only nuclei unite

(macronuclei degenerates but micronuclei divide a number of times)
